Question

1. Which detail best supports the idea that PPG knew their chemical

Answer 1

Answer:

C. "he was told to take on another ominous job. It was to be done  twice a day, usually after dusk, and always in secret." (  Paragraph 13)

Explanation:

The article "Lee Sherman and the Toxic Louisiana Bayou" tells the story of Lee Sherman and his work with PPG which turned him to be an ardent environmentalist. His work in that factory led him to advocate for safer working conditions and also for the environment as a whole.

The article narrates how Sherman was employed by Pittsburgh Plate Glass (PPG) where he was to work with chemicals harmful not only for humans but also for the environment. But despite all the harmful things, the company knew its dangerous works but had concealed them to the general public. The detail about how he had to dump tar "done twice a day, usually after dusk, and always in secret" shows that PPG knew their chemical dumping could have a negative effect but had decided to do it in secret.

Thus, the correct answer is option C.
