Question

both major parties; A) ARE CENTERED around a specific political and social philosophy b)are often decentralized and fragmented C)only operate on a local level D) concede elections when they do not have enough support

Answer 1

A) looks right, but it's not. The two parties aren't centered around A political and social philosophy. EACH party, though, has it's own political and social philosophy.

Sometimes both parties are decentralized and fragmented, but I wouldn't say the are often decentralized and fragmented.

C) and D) are obviously wrong.

I suggest you check your text materials to find out the expected answer.

Answer 2

I agree with Ms. Sue.

I suppose A could be correct if it were worded a bit differently:
Both major parties (A) are centered around specific political and social philosophies -- but even that's not phrased right. It would have to mean that each party has its own political and social philosophies.
