Hi chesstitans,
Thank you for your question. Let's start by figuring out what is different about each answer, and tackling one thing at a time. Here is what I noticed when looking over each answer quickly:
1. seem vs. seems
2. to oppose / to be opposed against / to be opposed to
If we look at the issue of "seem vs. seems," it's clearly a matter of subject/verb agreement. The verb is referring back to "The majority," which is a singular noun (a "majority" of anything is called a
collective noun, and is treated like one thing). So we need to stick with only answers that use the singular "seems." This means we can rule out answers C & E because they use a plural verb, which is incorrect.
Now, let's look at what we have left in answers A, B, & D:
A. seems to oppose
This answer is CORRECT because it's the most clear and concise answer.
B. seems to be opposed against
"Opposed" and "against" mean the same thing, so this answer is INCORRECT because it's redundant. You only need to say one or the other - both is too much!
D. seems to be opposed to
This is incorrect because it's overly wordy. Just saying "oppose" is enough.
There you go - answer A is correct because it uses proper subject-verb agreement, and it's not overly wordy or redundant.
