Passage 2: Unwanted Guests: The Dangers of Invasive Species (2016)
Groups of different animals affect one another in the natural world. For example, imagine that wolves and deer live in an area. A certain number of wolves need to eat a certain number of deer to survive. This keeps the population of the deer from getting too big. Similarly, the deer eat grass and vegetation. If there were more deer, they’d need to eat more grass.
The natural world is full of balances like these. Unfortunately, sometimes these balances are upset by invasive species. An invasive species is an animal or plant that has moved or been moved from its original environment to a new one. It has established a stable population there that is causing problems. Invasive species don’t cause problems in their original environments because they are kept in check by other plants and animals. In new environments, though, they have nothing stopping them from taking over.
One example of an invasive species is the zebra mussel. This animal originally only lived near Russia. Zebra mussels got into the Great Lakes by attaching themselves to the bottoms of ships. They now live in the Great Lakes too, where they upset the ecosystem. Zebra mussels eat algae, but so do fish. Many fish die as a result of there not being enough algae for all the animals to eat.
Plants can be invasive species too. Another example of an invasive species is the kudzu vine. Humans introduced the plant to the United States on purpose. Farmers were encouraged to grow it to protect their soil. Since then, it has gotten out of control. It now covers large parts of the South, outcompeting native plants for resources like water and sunlight.
Invasive species can cause environmental problems that are very difficult to fix. Because of this, it’s important to rethink introducing any species to a new environment. It’s also important to check to make sure when traveling that you are not bringing any plants or animals with you!
Which of the following excerpts from the passage best states its main idea?
"Invasive species don’t cause problems in their original environments because they are kept in check by other plants and animals."
"Invasive species can cause environmental problems that are very difficult to fix."
"One example of an invasive species is the zebra mussel."
"Groups of different animals affect one another in the natural world."
"Plants can be invasive species too."
"Invasive species can cause environmental problems that are very difficult to fix."
To state the main idea of the passage, the correct answer is going to have to be not too general and not too specific. If it seems like a statement could describe a number of other things besides the topics the passage discusses, it's probably not a good main idea statement for that passage. On the other hand, if the statement only focuses on details that are only mentioned in a few paragraphs of the passage, it is also likely not a good main idea statement for that passage.
Let's skim over the passage and summarize what it discusses in each paragraph in a phrase or short sentence. Doing this can help us be more efficient when we consider the answer choices, as it will make it easier to spot any that are too general or too narrowly focused.
Paragraph 1: General introduction about how species affect one another in environments
Paragraph 2: Introduction and definition of invasive species
Paragraph 3: Example of invasive animal species (Zebra mussel)
Paragraph 4: Example of invasive plant species (Kudzu vine)
Paragraph 5: Summary and recommendations
Now, let's look at the answer choices.
"Groups of different animals affect one another in the natural world." - This answer choice is too broad. Animals affect one another in the natural world in a wide variety of different ways, but this passage talks about one specific way in which species can interact as a result of invasive species. This isn't a good expression of the passage's main idea.
"Plants can be invasive species too." - This answer choice is far too specific. The passage talks about invasive species and then mentions invasive plants as an example, so this isn't a good expression of the main idea of the passage.
"One example of an invasive species is the zebra mussel." - This answer choice is way too specific as well. The zebra mussel serves as an example of the passage's main topic, invasive species, so a statement about the zebra mussel being an example doesn't express the main idea of the passage very well.
The remaining two answer choices both have to do with invasive species:
"Invasive species don’t cause problems in their original environments because they are kept in check by other plants and animals." - This answer choice focuses on how invasive species don't have a negative influence on their original environments. The passage focuses more on the effects of invasive species after they have "invaded" a new area, not on how they fit into their original environments.
"Invasive species can cause environmental problems that are very difficult to fix." - This answer choice is correct. It focuses on how invasive species can cause problems in environments. This is what the passage focuses on, so this sentence is the best expression of its main idea.
Example Question #22 : Key Ideas And Details
Passage 1
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. Amphibians are in trouble because their habitat is being destroyed as trees are being cut down to make room for farms and roads. 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 from their plight. Scientists want the government to pass laws that protect amphibian habitats and limit pollution.
Passage 2
My name is Maria and I am an amphibian conservation biologist. My job is to protect amphibians and their natural habitats, develop educational programs and exhibits to engage the public about amphibian conservation, and research to develop tools that will allow scientists to reintroduce amphibians back into the wild. Conservation biologists are scientists who study and protect animals and their environments. I work in a zoo, but I often travel to places like Ecuador or Brazil to observe a variety of amphibians in their natural habitats. 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 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 like the Endangered Species Act that protect wildlife and their homes. She, in turn, needs to partner with government workers who can lobby and vote 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 protected space for amphibians to be released from the zoo and into a space where they can thrive.
What sentence best shows the main idea of passage 1?
“ Amphibians are in trouble because their habitat is being destroyed as trees are being cut down to make room for farms and roads”
“Amphibians are animals that spend part of their life in water and part on land, and have backbones”
“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 from their plight.”
“Between the destruction of their habitats and risks to frogs from pollution, frogs are at risk of endangerment and extinction.”
This is the best choice because it covers the majority of what the article talks about.
