Example Question #1 : Reading To Show Basic Understanding

Adapted from "Alice's Adventures in Wonderland" by Lewis Carroll (1865)

Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, 'and what is the use of a book,' thought Alice 'without pictures or conversation?'

So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her.

There was nothing so very remarkable in that; nor did Alice think it so very much out of the way to hear the Rabbit say to itself, 'Oh dear! Oh dear! I shall be late!' (when she thought it over afterwards, it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural); but when the Rabbit actually took a watch out of its waistcoat-pocket, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with curiosity, she ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge.

In another moment down went Alice after it, never once considering how in the world she was to get out again.

The rabbit-hole went straight on like a tunnel for some way, and then dipped suddenly down, so suddenly that Alice had not a moment to think about stopping herself before she found herself falling down a very deep well.

Why didn't Alice like her sister's book? 

Possible Answers:

The book had no pictures 

The book had no conversations

Both of the choices are correct

Neither of the choices are correct

Correct answer:

Both of the choices are correct

Explanation:

The answer to this question can be found directly in the passage. In the first sentence we are told why Alice didn't like her sister's book. 

"Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, 'and what is the use of a book,' thought Alice 'without pictures or conversation?'"

Both of the options are correct. 

Example Question #2 : Reading To Show Basic Understanding

Adapted from "Alice's Adventures in Wonderland" by Lewis Carroll (1865)

Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, 'and what is the use of a book,' thought Alice 'without pictures or conversation?'

So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her.

There was nothing so very remarkable in that; nor did Alice think it so very much out of the way to hear the Rabbit say to itself, 'Oh dear! Oh dear! I shall be late!' (when she thought it over afterwards, it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural); but when the Rabbit actually took a watch out of its waistcoat-pocket, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with curiosity, she ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge.

In another moment down went Alice after it, never once considering how in the world she was to get out again.

The rabbit-hole went straight on like a tunnel for some way, and then dipped suddenly down, so suddenly that Alice had not a moment to think about stopping herself before she found herself falling down a very deep well.

What was Alice doing right before she saw the rabbit? 

Possible Answers:

Deciding whether or not she wanted to pick daisies 

Reading with her sister

Looking at the clouds

Deciding whether or not she wanted to take a nap

Correct answer:

Deciding whether or not she wanted to pick daisies 

Explanation:

This answer can be found directly in the passage, so to answer this question, we need to find the part of the passage where Alice saw the rabbit, and then read the sentence(s) right before that point because we are looking for what Alice was going before she saw the rabbit. 

"So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her."

Based on this information, Alice was deciding whether or not to make a "daisy-chain" and go pick daisies right before she saw the rabbit.

She did say that she was tired, but she didn't mention taking a nap. The passage also does not mention Alice looking at clouds. She was reading with her sister, but that came before she was deciding whether or not to pick daisies. 

Example Question #31 : Reading

Adapted from "The Tongue-Cut Sparrow" in Japanese Fairy Tales (1904, trans. Teresa Peirce Williston)

A long time ago, in a little old house in a little old village in Japan lived a little old man and his little old wife.

One morning when the old woman slid open the screens that in that era formed the sides of all Japanese houses, she saw, on the doorstep, a poor little sparrow. She took him up gently and fed him. Then she held him in the bright morning sunshine until the cold dew was dried from his wings. Afterward she let him go, so that he might fly home to his nest, but he stayed to thank her with his songs.

Each morning, when the pink on the mountain tops told that the sun was near, the sparrow perched on the roof of the house and sang out his joy. The old man and woman thanked the sparrow for this, for they liked to be up early and at work. But near them there lived a cross old woman who did not like to be awakened so early. At last she became so angry that she caught the sparrow and cut his tongue. Then the poor little sparrow flew away to his home, but he could never sing again.

When the kind woman knew what had happened to her pet she was very sad. She said to her husband, "Let us go and find our poor little sparrow." So they started together, and asked of each bird by the wayside, "Do you know where the tongue-cut sparrow lives? Do you know where the tongue-cut sparrow went?"

In this way they followed until they came to a bridge. They did not know which way to turn, and at first could see no one to ask. At last they saw a bat hanging head downward, taking his daytime nap. "Oh, friend bat, do you know where the tongue-cut sparrow went?" they asked.

"Yes. Over the bridge and up the mountain," said the bat. Then he blinked sleepy eyes and was fast asleep again.

They went over the bridge and up the mountain, but again they found two roads and did not know which one to take. A little field mouse peeped through the leaves and grass, so they asked him, "Do you know where the tongue-cut sparrow went?"

"Yes. Down the mountain and through the woods," said the field mouse.

Down the mountain and through the woods they went, and at last came to the home of their little friend.

When he saw them coming the poor little sparrow was very happy indeed. He and his wife and children all came and bowed their heads down to the ground to show their respect. Then the sparrow rose and led the old man and the old woman into his house, while his wife and children hastened to bring them boiled rice, fish, and cress.

After they had feasted, the sparrow wished to please them still more, so he danced for them what is called the "sparrow dance."

When the sun began to sink, the old man and woman started for home. The sparrow brought out two baskets. "I would like to give you one of these," he said. "Which will you take?" One basket was large and looked very full, while the other one seemed very small and light.

The old people so thought they would not take the large basket, for that might have all the sparrow's treasure in it, so they said, "The way is long and we are very old, so please let us take the smaller one."

They took it and walked home over the mountain and across the bridge, happy and contented. When they reached their own home they decided to open the basket and see what the sparrow had given them. Within the basket they found many rolls of silk and piles of gold, enough to make them rich, so they were more grateful than ever to the sparrow.

The cross old woman who had cut the sparrow's tongue was peering in through the screen when they opened their basket. She saw the rolls of silk and the piles of gold, and planned how she might get some for herself.

The next morning she went to the kind woman and said, "I am so sorry that I cut the tongue of your sparrow. Please tell me the way to his home so that I may go to him and tell him I am sorry."

The kind woman told her the way and she set out. She went across the bridge, over the mountain, and through the woods. At last she came to the home of the little sparrow. He was not so glad to see this old woman, yet he was very kind to her and did everything to make her feel welcome. They made a feast for her, and when she started home the sparrow brought out two baskets as before. Of course the woman chose the large basket, for she thought that would have even more wealth than the other one.

It was very heavy, and caught on the trees as she was going through the wood. She could hardly pull it up the mountain with her, and she was all out of breath when she reached the top. She did not get to the bridge until it was dark. Then she was so afraid of dropping the basket into the river that she scarcely dared to step. When at last she reached home she was so tired that she was half dead, but she pulled the screens close shut, so that no one could look in, and opened her treasure.

Treasure indeed! A whole swarm of horrible creatures burst from the basket the moment she opened it. They stung her and bit her, they pushed her and pulled her, they scratched her and laughed at her screams. At last she crawled to the edge of the room and slid aside the screen to get away from the pests. The moment the door was opened they swooped down upon her, picked her up, and flew away with her. Since then nothing has ever been heard of the old woman.

Which of the following lines demonstrates that the sparrow is polite to people who visit him, even if they have been mean to him?

Possible Answers:

"[The sparrow] was not so glad to see this old woman, yet he was very kind to her and did everything to make her feel welcome. They made a feast for her . . . "

"Then the sparrow rose and led the old man and the old woman into his house, while his wife and children hastened to bring them boiled rice, fish, and cress."

"After [the old man and the old woman] had feasted, the sparrow wished to please them still more, so he danced for them what is called the 'sparrow dance.'"

"The old people so thought they would not take the large basket, for that might have all the sparrow's treasure in it, so they said, 'The way is long and we are very old, so please let us take the smaller one.'"

"At last [the old woman] became so angry that she caught the sparrow and cut his tongue. Then the poor little sparrow flew away to his home, but he could never sing again."

Correct answer:

"[The sparrow] was not so glad to see this old woman, yet he was very kind to her and did everything to make her feel welcome. They made a feast for her . . . "

Explanation:

The fact that the sparrow is polite to the old man and his wife doesn't support this inference. We need to find the part of the story that demonstrates that the sparrow is nice to visitors even if they have been mean to him, and the old man and his wife are never mean to the sparrow in the story. Who is mean to the sparrow? The old woman who cuts his tongue is mean to him, so our answer choice should mention her. Only two answer choices mention the mean old woman: one is from the part of the passage where she cuts the sparrow's tongue, and the other is from when she is visiting the sparrow. The latter is the best answer choice: "[The sparrow] was not so glad to see this old woman, yet he was very kind to her and did everything to make her feel welcome. They made a feast for her . . . " The passage tells us that even though the old woman had been mean to the sparrow, "he was very kind to her and did everything to make her feel welcome," including serving her "a feast." This demonstrates how the sparrow is nice to guests even if they have been mean to him.

Example Question #4 : Reading To Show Basic Understanding

A Look Into Space

Did you know that we used to think that there were nine planets that made up the solar system? Up until 2006, Pluto was considered to be the ninth planet and was located furthest away from the sun in our solar system. However, since 2006 Pluto has been considered to be a “dwarf planet” because it is too small to be considered a planet. Now that Pluto is not considered a planet, only eight planets are left to make up our solar system. The order of the planets from the sun is as follows: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. 

Mercury is the planet closest to the sun; however, can you believe that Mercury is not the planet with the hottest temperatures in our solar system? Well, believe it because Venus is the planet with the highest temperatures! The only award that sets Mercury apart from any other planet in the solar system is that it is the smallest planet. 

Earth is the planet where you and I live. Earth is the only planet currently known to be the home of living things. However, Mars does show some signs that there may be water on the planet, which is necessary for living things to grow and live on Mars. Maybe one day we will learn that aliens really do live on Mars!

Jupiter is the largest planet is the solar system, but it has the shortest days out of all of the planets because it turns so quickly. A day on Earth is 24 hours long, but a day on Jupiter is less than 10 hours long and a day on Saturn is just over 10 hours long. If we lived on Jupiter or Saturn, then we would spend most of the day in school! 

Uranus is not the furthest planet from the sun, but it is the coldest. Even though Uranus is the coldest planet, Neptune might have the worst weather. One storm on Neptune lasted for about 5 years! Could you imagine a storm lasting for 5 years on Earth? 

One fun thing about science is that we are always learning something new because science can change. We could learn more unknown, fun facts about the solar system in the future! 

Based on the order of the planets, which planet would you assume would be the warmest? 

Possible Answers:

Venus

Mars

Mercury

Earth

Correct answer:

Mercury

Explanation:

This question is asking us to make an assumption, which mean the answer won't be found directly in the next. We will have to use details from the text to make our assumption. 

The first paragraph gives us the order of the planets from the sun. "The order of the planets from the sun is as follows: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune."

Though we are later told that Venus is the warmest planet, one would assume that Mercury would be the warmest planet because it is the closest planet to the sun. Mercury is the correct answer. 

Example Question #5 : Reading To Show Basic Understanding

Passage and table adapted from "Why Leaves Change Color" on "Northeastern Area," a website by the USDA Forest Service. <https://www.na.fs.fed.us/fhp/pubs/leaves/leaves.shtm>.

There are two main types of trees: coniferous trees and deciduous trees. Coniferous trees have small, needle-like leaves. They keep these leaves all year. One example of a coniferous tree is a pine tree, which has green needles during all seasons. In contrast, deciduous trees lose their leaves every autumn. Before these leaves drop and blow away, they change from green to colors like red, orange, yellow, and brown.

Have you ever wondered why deciduous leaves change color in the fall? This color change is caused by a chemical process in the cells of tree leaves.

Green leaves are green because they contain a green molecule, chlorophyll. This is a very important molecule in the natural world. Leaves use this molecule to turn carbon dioxide, sunlight, and water into sugar and oxygen in a process called “photosynthesis.” So, chlorophyll lets the plant store energy as sugar, which it can use as food. It also lets the plant provide food for anything that eats it, like a cow, a bird, or even a human! 

So, what does chlorophyll, a green molecule, have to do with autumn leaf colors? Deciduous leaves also contain molecules of other colors, but the chlorophyll in the leaves covers them up in the summer. In the fall, deciduous trees stop making chlorophyll. Eventually there is no more chlorophyll in their leaves. The colors of the other molecules show through. The colors of these other molecules are the colors we see in autumn leaves. The next time you see colorful leaves in the fall, you’ll know more about the chemistry at work!

Which of the following would you expect to be listed in the left column of the table in a horizontal row with the color “Green” in the right column of the table?

Possible Answers:

No tree would be listed with “green” in the right column of the table

A pine tree

A deciduous tree

Moss

Correct answer:

A pine tree

Explanation:

This question is asking us what we could expect to find in a hypothetical entry in the presented table. Specifically, it is asking which answer choice you would be most likely to find associated with "Green" as an entry in the right column of the table.

"A deciduous tree" doesn't make any sense based on what we learn in the passage. The right column is labeled "Color of Leaves in Fall," and in the passage, we learn that deciduous trees' leaves turn from green to other colors in the fall when they stop making chlorophyll.

On the other hand, "moss" can't be the correct answer either. While moss is green, it is not a "Type of Tree," and that's what the left column of the table is labeled. So, we need to pick out an answer choice that is both a type of tree and a tree that we would expect to remain green in the fall. While "No tree would be listed with 'green' in the right column of the table" might seem like a good answer, the best answer is "A pine tree." Why is this? In the first paragraph of the passage, it states, "One example of a coniferous tree is a pine tree, which has green needles during all seasons." A pine tree is both a type of tree and something that remains green in the autumn, so it is the correct answer.

How does the information presented in the table relate to the information presented in the passage?

Possible Answers:

The passage talks about the process of leaf color change, and the table provides specific examples of the different colors different trees’ leaves turn.

The passage lists the different colors trees turn, and the table explains why they each turn different colors.

The passage explains what photosynthesis is, and the table explains the different stages of photosynthesis.

The passage provides a long list of trees and states whether they are coniferous or deciduous, and the table explains the difference between coniferous and deciduous trees.

Correct answer:

The passage talks about the process of leaf color change, and the table provides specific examples of the different colors different trees’ leaves turn.

Explanation:

The passage describes the difference between two types of trees, coniferous and deciduous. It then goes on to explain how the relationship between amounts of different molecules causes deciduous trees' leaves to change color in the fall. How does this information compare to the data that the table presents? The table consists of two columns. One is labeled "Type of Tree," and the other is labeled "Color of Leaves in Fall." This table associates different types of trees with the different colors their leaves turn in the fall. 

What can we say about how the passage and the table relate?

"The passage explains what photosynthesis is, and the table explains the different stages of photosynthesis." - The passage explains what photosynthesis is, but the table doesn't have anything to do with explaining the different stages of photosynthesis. So, this answer is not correct.

"The passage provides a long list of trees and states whether they are coniferous or deciduous, and the table explains the difference between coniferous and deciduous trees." - Nowhere in the passage do we find a long list of trees and information about whether they are coniferous or deciduous. The passage only provides one example when it states, "One example of a coniferous tree is a pine tree." 

"The passage lists the different colors trees turn, and the table explains why they each turn different colors." - This is not the correct answer. The passage does not list different colors trees turn, and the table does not explain why different trees turn different colors.

"The passage talks about the process of leaf color change, and the table provides specific examples of the different colors different trees’ leaves turn." - This is the correct answer! The passage talks about the process of leaf color change because it explains how it is caused by amounts of different chemicals that relate to one another differently during different parts of the year. The table provides specific examples by listing different kinds of trees and the specific color that each kind of tree's leaves turn in the fall.

The colors of these other molecules are the colors we see in autumn leaves. The next time you see colorful leaves in the fall, you’ll know more about the chemistry at work!

According to the passage, leaves turn color in the fall because __________.

Possible Answers:

they start to perform photosynthesis

they are eaten by hungry animals

they no longer contain chlorophyll

they start to make chlorophyll

Correct answer:

they no longer contain chlorophyll

Explanation:

This question asks you about a cause and effect relationship explained in the passage. The question states an effect, ("leaves turn color in the fall") and asks you to figure out why this occurs ("because __________.") The reason why leaves turn color in the fall is a major topic discussed in the passage. In the last paragraph, readers learn exactly why this color change occurs:

So, what does chlorophyll, a green molecule, have to do with autumn leaf colors? Deciduous leaves also contain molecules of other colors, but the chlorophyll in the leaves covers them up in the summer. In the fall, deciduous trees stop making chlorophyll. Eventually there is no more chlorophyll in their leaves. The colors of the other molecules show through. The colors of these other molecules are the colors we see in autumn leaves. 

This part of the passage explains that it is a lack of chlorophyll that allows other molecules' colors to show through as the autumn colors of deciduous trees' leaves. The correct answer is "they no longer contain chlorophyll."

Passage 2: Adapted from "Cyanocitta cristata: Blue Jay" in Life Histories of North American Birds, From the Parrots to the Grackles, with Special Reference to Their Breeding Habits and Eggs by Charles Bendire (1895)

The beauty of few of our local birds compares to that of the Blue Jay. One can’t help admiring them for their amusing and interesting traits. Even their best friends can’t say much in their favor, though. They destroy many of the eggs and young of our smaller birds. A friend of mine writes, “The smaller species of birds are utterly at [the Blue Jay’s] mercy in nesting time. Few succeed in rearing a brood of young. It is common in the woods to hear Vireos lamenting for their young that the Jay has forcibly carried away. Vast numbers of eggs are eaten and the nests torn up.”

Still, I cannot help admiring Blue Jays, because they have good traits as well. They are cunning, inquisitive, good mimics, and full of mischief. It is difficult to paint them in their true colors. Some writers call them bullies and cowards. Perhaps they deserve these names at times, but they possess courage in the defense of their young. But it is unfortunate that they show so little consideration for the feelings of other birds.

It is astonishing how accurately the Blue Jay is able to imitate the various calls and cries of other birds. These will readily deceive anyone. They seem to delight in playing tricks on their unsuspecting neighbors in this manner, apparently out of pure mischief. They are especially fond of teasing owls, and occasionally hawks; however, sometimes this has disastrous results for the Blue Jays.

Why can we infer that imitating the calls of hawks and owls occasionally “has disastrous results for the Blue Jays,” as the passage says in its last line?

Possible Answers:

Sometimes the blue jay doesn’t imitate the calls of hawks and owls correctly.

Sometimes the hawks and owls catch and eat the blue jay imitating their calls.

Sometimes the blue jay imitating the hawks and owls scares other birds away from their nests, letting the blue jay eat the other birds’ eggs.

Sometimes the hawks and owls can’t find the blue jay that is imitating their calls.

Correct answer:

Sometimes the hawks and owls catch and eat the blue jay imitating their calls.

Explanation:

If you know that hawks and owls are predators and can infer that they would eat a blue jay if they could catch one, this question may have been more straightforward; however, this knowledge is not necessary to answer the question correctly. You can narrow down the answer choices to the point where this is the only reasonable one. Let's figure out the correct answer using this strategy.

The correct answer choice will involve something bad happening to the blue jays based on their imitating the calls of hawks and owls. The only answer choice in which something bad happens to the blue jay based on its imitating these calls is "Sometimes the hawks and owls catch and eat the blue jay imitating their calls." If a blue jay were to scare other birds away by imitating hawk and owl calls and eat the other birds' eggs, that would be bad for the other birds, but not for the blue jay. If the blue jay weren't found by the hawks and owls when the jay imitated their calls, that wouldn't be a bad thing for the blue jay. (It would actually be a good thing—the blue jay wouldn't get eaten!) Finally, if a blue jay didn't imitate the calls of hawks and owls correctly, that's just an error on their part. The mistake doesn't involve anything bad happening to them.

Example Question #9 : Reading To Show Basic Understanding

Passage One

Ecuador, in South America, is home to 417 types of frogs and toads. Many of these species, or types of frogs, are at risk of dying out. In the last 50 years, many amphibian species have gone extinct. Salamanders, frogs, and toads are all amphibians. Amphibians are animals that spend part of their life in water and part on land, and have backbones. Amphibians must live near water. Amphibian habitats can be found in forests, woodlots, meadows, springs, wetlands, streams, rivers, lakes, ponds, bogs, marshes. Frogs and toads are in trouble because their habitats are being destroyed as trees are being cut down to make room for farms and roads. Wetland spaces where frogs live are being drained and paved over. As these spaces are removed, the places frogs, toads, and salamanders can live shrink. 

Amphibians also absorb pollution easily, because they breathe through their skin. Amphibians are usually the first to disappear when an environment is under threat from pollution. Due to pollution, some frogs are born with deformed, or wrongly shaped, body parts, such as extra legs and eyes. Frogs with deformed body parts are a clue for scientists that an environment is suffering. Between the destruction of their habitats and risks to frogs from pollution, frogs are at risk of endangerment and extinction. Scientists are working to save amphibians. Scientists want the government to pass laws that protect amphibian habitats and limit pollution. 

Passage Two

My name is Maria and I am an amphibian conservation biologist. This means I am a scientist who studies and protects frogs, toads, and salamanders.  My job is to protect amphibians and their natural habitats, share this knowledge with the public,  and research ways to help reintroduce frogs in captivity back into the wild. I have the best job in the world.  I work in a zoo, but I often travel to places like Brazil to observe amphibians in their natural habitats in the wild. Brazil, for example, has 1,022 different types of frogs, toads and salamanders! In my work at the zoo, I specialize in only a small portion of that number. Here in the zoo, we have many amphibians in our care because some or all of their natural habitats, or homes, were destroyed.  We are not alone in our work to protect amphibians. Many people, in many kinds of jobs, are helping protect amphibians and their habitats. I partner with other scientists and lawyers, like my friend Fernanda,  to help create laws that best support the conservation, or protection, of amphibians. Fernanda is an environmental lawyer who works to create laws that protect diverse wildlife. She, in turn, needs to partner with government workers to help get laws passed. Together, our goal is to work together to build a world where these amphibians have safe space to live outside of the zoo, in their natural habitat, protected from pollution or loss of space. We are working with a facility in Brazil to build a safe wild space for amphibians to be released from the zoo and into a space where they can thrive. The new habitat will be a protected wetland for these amphibians.

According to passage 1, what is the main threat for frogs and toads?

Possible Answers:

“Amphibians must live near water.”

“Frogs are at risk of endangerment and extinction.”

“Frogs with deformed body parts are a clue for scientists that an environment is suffering”

“Amphibians are animals that spend part of their life in water and part on land”

Correct answer:

“Frogs are at risk of endangerment and extinction.”

Explanation:

This is the quote that best summarizes the threat to frogs.

Frogs and toads are in trouble because their habitats are being destroyed as trees are being cut down to make room for farms and roads. Wetland spaces where frogs live are being drained and paved over. As these spaces are removed, the places frogs, toads, and salamanders can live shrink. 

Amphibians also absorb pollution easily, because they breathe through their skin. Amphibians are usually the first to disappear when an environment is under threat from pollution. Due to pollution, some frogs are born with deformed, or wrongly shaped, body parts, such as extra legs and eyes. Frogs with deformed body parts are a clue for scientists that an environment is suffering. Between the destruction of their habitats and risks to frogs from pollution, frogs are at risk of endangerment and extinction. Scientists are working to save amphibians. Scientists want the government to pass laws that protect amphibian habitats and limit pollution. 

Passage Two

My name is Maria and I am an amphibian conservation biologist. This means I am a scientist who studies and protects frogs, toads, and salamanders.  My job is to protect amphibians and their natural habitats, share this knowledge with the public,  and research ways to help reintroduce frogs in captivity back into the wild. I have the best job in the world.  I work in a zoo, but I often travel to places like Brazil to observe amphibians in their natural habitats in the wild. Brazil, for example, has 1,022 different types of frogs, toads and salamanders! In my work at the zoo, I specialize in only a small portion of that number. Here in the zoo, we have many amphibians in our care because some or all of their natural habitats, or homes, were destroyed.  We are not alone in our work to protect amphibians. Many people, in many kinds of jobs, are helping protect amphibians and their habitats. I partner with other scientists and lawyers, like my friend Fernanda,  to help create laws that best support the conservation, or protection, of amphibians. Fernanda is an environmental lawyer who works to create laws that protect diverse wildlife. She, in turn, needs to partner with government workers to help get laws passed. Together, our goal is to work together to build a world where these amphibians have safe space to live outside of the zoo, in their natural habitat, protected from pollution or loss of space. We are working with a facility in Brazil to build a safe wild space for amphibians to be released from the zoo and into a space where they can thrive. The new habitat will be a protected wetland for these amphibians.

 According to passage 1, why are frogs being born with extra legs?

Possible Answers:

Their habitats are being destroyed

There are many different types of frogs

They are endangered

Their bodies have absorbed pollution

Correct answer:

Their bodies have absorbed pollution

Explanation:

The text says that frogs are being born with extra limbs because of pollution absorbed in the bodies of parent frogs.
