The assumption question i.e the assumption itself is like a bridge to tie the stimulus and the conclusion. It is like the missing link.

Quote:
Consequently, once the housing is occupied, the annual number of the forest's deer hit by cars will be much higher than before construction started.
D is the answer because, actually, if you do not have deer all the argument falls apart. You have to have sufficient deer population to sustain your argument and conclusion.
B talks about the attraction of the deer alongside the road. It is out of scope.You care about of deer's number not the attraction or not.
Hope now is more clear.
