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.

Given what you read in passage 1 and 2, what can you infer about the best way for change to happen to protect amphibians?

“Once upon a time, there was a little prince. His father spoiled him, and his grandfather doted on him even more.”

The prince's grandfather spoiled him even more than his father did. 

 Carol and Nisha are twin sisters. They are fourteen years of age. This is an example of:

A Voice for Freedom and Song

Marian Anderson was a world-class singer. By the year 1939, Marian had sung for people around the world, including kings and presidents. Her dream was to sing at Constitution Hall, but, in her mind, she viewed it as something that would never happen. The owners, the Daughters of the American Revolution (DAR), would not allow her to sing because she was African-American. 

Marian was used to dealing with people who only saw her for her skin color. When she was younger, she applied to become a student at a music school. She was denied entrance because of her race. In the early 1900s, when Marian began her singing career, segregation still kept African-American people from achieving their goals and dreams. 

Marian performed in 1925 in a voice contest in New York and won. She was able to sing with the New York Philharmonic! She thought doors would start opening for her in the United States, but instead, people foolishly turned her away. Marian traveled to Europe in 1928, and there she became quite popular. 

In 1939, she returned to the United States, but she was still subject to the cruelty and unfairness of racism and segregation. When Marian attempted to sing at Constitution Hall, the DAR had many excuses for why she couldn’t perform. They tried telling her that the dates weren’t available, or that they weren’t booking new performers. Eventually, they told Marian the truth: she couldn’t perform because they only allowed white musicians.

This rejection inspired thousands of people to rally together against the horrible segregation laws that prevented many from hearing Marian’s beautiful voice. First Lady Eleanor Roosevelt resigned from the DAR and publicly shamed them for their treatment of African-American performers. Mrs. Roosevelt and her staff arranged a concert at the Lincoln Memorial for Marian to perform. Seventy-five thousand people attended, standing against discrimination and getting to hear Marian sing.

After the DAR incident, Marian took a stand and refused to sing for segregated crowds. She finally achieved her dream of singing at Constitution Hall when the DAR reversed its policy on allowing African-American performers. Marian retired from performing in 1964, the same year that the Civil Rights Act was signed. Along with other brave activists, she used her talents to advocate for justice, and her voice helped create lasting change against racism and segregation in the United States.

How did First Lady Eleanor Roosevelt’s view of racism and segregation compare to the DAR’s?

Young Enterprise Services

Young Enterprise Services (YES) is a program created to encourage entrepreneurship in 14- to 18-year-olds who have already shown a clear ability for starting businesses. The program, which began in 2002, has provided loans, grants, and counseling—in the form of workshops and individual meetings with entrepreneurs—to over 7500 young people. The future of YES, however, is now at risk.

One complaint is that the funds that YES distributes have disproportionately gone to young people from low-income families. Though no one has claimed that any of the recipients of YES funds have been undeserving, several families have brought lawsuits claiming that their funding requests were rejected because of the families’ high levels of income. 

Another challenge has been making sure that a young person, not his or her family, is receiving the funding. The rules state that the youth must create the business plan and that any profits above $1,000 be placed in a bank account. The rules say that the money can only be used for education, investment in the business, and little else. There have been cases of parents or even a neighbor using the money for their business.

On the other hand, YES has had some real success stories. A 14-year-old girl in Texas used the knowledge and funding she received through the program to connect with a distributor who now carries her line of custom-designed cell phone covers. Two brothers in Alaska have developed an online travel service for young people vacationing with their families. Both of these businesses are doing well and earning money. Unfortunately, these and other successes have received little media coverage. This is a shame, but one that can be fixed.

Coal Passage 1

The typical coal plant in the United States creates more than 125,000 tons of ash and 193,000 tons of sludge each year. On average, 42% of coal combustion waste ponds and landfills are unlined. This means that the substances in the waste can seep into the ground and nearby lakes. Some of the substances include arsenic, mercury, chromium, and cadmium. These can contaminate drinking water supplies and directly contact the consumers who drink water from these areas. The disposal of coal plant waste has damaged many ecosystems. Once the coal plants have cycled through billions of gallons of water to cool the system, it is dumped back into the river, ocean, or lake it is pulling water from. When this hot water is released back into the body of water, it creates “thermal pollution,” which can harm the plants and animals living in this area. Many plants add chemicals to their cooling water, which is released back into the lake, ocean, or river with the hot water.

Coal Passage 2

Coal is a concentrated form of prehistoric biomass, plant life, and is the most plentiful fossil fuel produced in the United States. More than 90 percent of the coal consumed in the US is used to generate electricity. Coal power is also an essential industry source for making steel, cement, and paper, and is used in numerous other industries. Coal was a valuable resource that powered trains, steamships, and other forms of transportation for centuries. Coal is essential to the US economy and provides consumers with affordable electricity. The mining of coal and the use of coal power plants provide vital jobs to many American citizens. In 2018 15% of U.S. coal production was exported to other countries. Exporting coal has a positive effect on the United State’s economy.

Which author would be most likely to promote the use of coal, and which piece of evidence supports the claim?

Adapted from Aesop’s The Ants & the Grasshopper (620-560 BCE)

One bright day in late autumn, a family of Ants were bustling about in the warm sunshine, drying out the grain they had stored up during the summer, when a starving Grasshopper, his fiddle under his arm, came up and humbly begged for a bite to eat.

"What!" cried the Ants in surprise, "haven't you stored anything away for the winter? What in the world were you doing all last summer?"

"I didn't have time to store up any food," whined the Grasshopper; "I was so busy making music that before I knew it, the summer was gone."

The Ants shrugged their shoulders in disgust.

"Making music, were you?" they cried. "Very well; now dance!" And they turned their backs on the Grasshopper and went on with their work.

When comparing the Grasshopper and the Ants, there is a contrast in their behavior and attitudes. How could the Grasshopper and Ants be described?

Echolocation is a behavior in which animals emit calls and then listen to the echoes that bounce back off of stable things in the environment. This behavior can be used to navigate and to find food or mates. Orcas, dolphins, sperm whales, and pilot whales are all creatures that use this function to gather information. They release small bursts of air from air sacs in their heads and then through their mouths. This burst of air will make a click or ringing sound. The sound will bounce off an object and return to the whale or dolphin. That information is then transferred to a centralized place (the brain) where it is processed, and the organism responds in ways that will help it survive and reproduce.

Platypus have a "sixth-sense" that allows them to hunt underwater: electroreception. To find meals in the mud, it uses its bill to detect movements and subtle electric fields produced by its prey. Receptors on the bill detect changes in pressure and motion. Two types of receptors track the electrical signals produced by small prey when they contract their muscles. The platypus moves its head side-to-side to determine its next meal's direction and distance by collecting and processing this sensory information. The platypus has about 40,000 of these special receptors.

How are dolphins and platypus similar?
