I just finished the MGMAT online sentence correction module and unless I am missing something I believe that some of their answers contradict their rules they teach.

For instance:

The number of acres destroyed by wildfires, which have become an ongoing threat due to drought and booming population density, have increased dramatically over the past several years, prompting major concern among local politicians.

A - have become an ongoing threat due to drought and booming population density, have increased
B - have become an ongoing threat due to drought and booming population density, have been increasing
C - has become an ongoing threat because of drought and booming population density, has increased
D - have become an ongoing threat due to drought and booming population density, has increased
E - have become an ongoing threat because of drought and booming population density, has increased

According to the rules for "number of" are:

"The number of" always takes a singular verb
"A number of" always takes a plural verb

If this is true than how can the above question have an answer with a plural verb.

Am I missing something here or do they have a trend in contradicting themselves in their practice questions?
If you have any questions

the number of.. is singular
"which" does not refer back to "the number of" but it refers back to wildfires (plural so "have become" is correct)

so i had it narrowed down to D or E.
hard pick is the answer E???

yes! just remember that "which" is a non-essential / non-restrictive clause (can be taken out and sentence would still make sense)

The number of acres destroyed by wildfires, which have become an ongoing threat because of drought and booming population density, has increased dramatically over the past several years, prompting major concern among local politicians.

How to differentiate between (D) and (E), i.e. "due to" and "Because of"?
