We need the passage to help
"The domesticated generations fell from him" means that Buck is losing his civilized characteristics (B).
In this passage, Buck is feeling more and more estranged from where he and his ancestors ("generations") originally come from: as he gets a taste of wild life, he feels less and less like a pet ("domesticated") and more like a feral dog or a wolf. He is forgetting his stay-at-home ways ("fell from him") and sees new instincts grow in him, such as the drive to fight and hunt in a pack.
The answer is B because it puts a coma in the correct spot to pause between the first half of the sentence and the second. The others either randomly placed a period, using the wrong word choices, or made it a run on sentence. :)
A. settlement
hope it helps you!
Huh... this seems to be an opinion question.
No matter, ill try.
It depends on the figure you look at. Partns would be B. governments? Could be all of them. I see how you got confused. Unles this is an opinion question, you may have to guess.
