Question

Now answer the following questions about both passages, “Rachel Carson, Environmental Pioneer” and “A Brief History of DDT.”

How are the central ideas best supported in both passages?
A. With evidence to support a harmful effect on the entire ecological system due to the use of harmful chemicals
B. With opinions about the dangers of environmental pollutants C.
With facts about decreasing bird populations
D. With facts about the negative effects of DDT

Answer 1

The passages are supported by evidence of harm to ecosystems and factual impacts of DDT usage, leading to increased awareness and a subsequent ban in agriculture. Option A and D is the best fit choice of answers.

Step-by-step explanation:

The central ideas are best supported with facts about the negative effects of DDT. The central ideas in both passages, “Rachel Carson, Environmental Pioneer” and “A Brief History of DDT,” are best supported by evidence to support a harmful effect on the entire ecological system due to the use of harmful chemicals and facts about the negative effects of DDT. These two key points are highlighted through real-world impacts observed and documented, such as harm to bird populations, which were affected by eggshell thinning due to DDT bioaccumulation. Rachel Carson's Silent Spring brought significant awareness to these issues, which eventually led to the banning of DDT in U.S. agriculture in 1972.
