Ineed what way is t. c. boyle’s "top of the food chain" an example of satire? a. it focuses on harm to the environment. b. it directly criticizes members of congress. c. it makes a point without directly stating it. d. it depicts the behavior of animals and people.

I believe the correct answer is C. it makes a point without directly stating it.
Satire is often used by authors who want to criticize something or someone without having to explicitly do that - they use metaphors in order to mock them without them realizing that they have been exposed to such ridicule. Boyle is trying to mock the government in his work by comparing its members to animals, which he does in order to conceal his true intentions.
