Analyze Interactions Between Individuals, Events, Ideas Practice Test

In 1962, Rachel Carson (an individual) published the book Silent Spring. Carson argued for the idea that humans are part of a connected ecosystem, so chemicals used in one place can harm animals and people elsewhere. The book described how the pesticide DDT could build up in food chains and weaken bird eggs. Many readers were shocked, and environmental groups organized letter-writing campaigns and public meetings (events). Chemical companies tried to discredit Carson, but scientists tested her claims and found strong evidence that some pesticides caused serious damage. As public pressure grew, the U.S. government held hearings and later restricted DDT use (an event). These actions helped spread the broader idea of environmental responsibility and encouraged schools to teach ecology more often.

Which choice best traces how an individual influenced an event in the passage?

In the early 1900s, Dr. Alice Hamilton (an individual) visited factories in Illinois to study why so many workers were getting sick. She believed in the idea that public health should protect people at work, not just treat them after they were ill. After interviewing workers and collecting samples, Hamilton published reports showing that lead dust was poisoning employees. Her evidence helped convince state leaders to hold public hearings (an event). During the hearings, factory owners argued that new rules would cost too much, but workers and doctors described real cases from Hamilton’s research. The hearings led Illinois to pass stricter safety rules and inspections (another event). Over time, these new laws strengthened the idea that the government has a responsibility to prevent workplace harm, and other states copied the approach.
