I’m sorry, what are we talking about?
Answer: share his desire to restore the world to its pristine condition, using an unstructured format.
The poem "Homework" by Allen Ginsberg uses free verse to show the desire the author has to fix the problems of the world, and to return the world to a time when humans had not spoilt it yet. He uses an unstructured format for this purpose. His desire to return the world to a pristine condition is displayed when he cites several issues the world has due to human activity, such as oil spills and smog in the atmosphere.
C) Pitchers threw at his head.
This line "Pitchers through at his head." uses the incorrect "through". This "through" means to go in and out of something, like a doorway. I walked through the doorway into the other room. The sentence needs the "threw" that means to take an object with your hand and propel it to another location. Threw is the past tense of the word throw. It is an irregular past tense verb, so it doesn't follow the rule of adding /ed/ to create past tense.
I believe the answer is : D ) 300 years.
