I think D is the best answer choice. for a work written around the time of the salem witch trials, you can better understand why extreme fear and condemnation of witchcraft might show up, and the author's purpose is a major thing to understand a work. C doesn't really make sense, because historical context is based on facts, so the context doesn't so much help you understand an author's attitude/opinion. B is true to some degree, but D is still a stronger answer as B is somewhat circular; historical context is an inherent part of a historical character? and A doesn't even make sense to me but i personally would go with D
What do we have to find here ? Hahaha
In this sentence :
"You also learn what it takes to make money: a lot of effort.”
The main verb is "learn". The verb Takes is also a verb but since it is within the next clause and it is the verb of the Cataphoric refrence "it" such verb cannot be considered the main verb of the sentence.
So your final aswer is Learn.
