1. Which detail best supports the idea that PPG knew their chemical dumping could have negative effects on the environment?
A "The next afternoon, Sherman's boss asked him to help search for
the bodies of the dead workers." (Paragraph 4)
B "Eventually the general foreman issued badges to the workers to
record any overexposure to dangerous chemicals, Sherman says,
"but the foreman made fun of them." ( Paragraph 10)
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)
D "In 1980, after 15 years of working at PPG, Sherman was
summoned and found himself facing a seven-member termination
committee." ( Paragraph 21)

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.
