Most movie critics dislike Hollywood blockbusters.

I think the answer is wrong here.
My reasoning for C to be must true is
Most movie critics dislike Hollywood blockbusters. and Some people who dislike Hollywood blockbusters are huge fans of theater.

As per my limited understanding, Option a does not need to be true. My reasoning is:
the arguments does mentions :
If someone dislikes Hollywood blockbusters they are a snob
but reverse need not to be true. There may be some "snob" who does not dislike Hollywood blockbuster

Please correct me if i am wrong.

SALAKSHYA, perhaps quantifying things would help here.

1. A scenario where option C does not have to be true.
->Number of movie critics = 100, no. of movie critics that dislike Hollywood blockbusters = 60 (most means more than 50%)
->Total number of people who dislike hollywood busters = 10,000,000 (Note that there is no limitation to the number of people who dislike hollywood busters).
->The relevant statement given in the question - Some people who dislike Hollywood blockbusters are huge fans of theater. Some means more than 1.
->Now think about it, why would C need to be true? Consider that there are only 2 people (out of the 10 million that dislike hollywood busters) that are fans of theatre. Why would these 2 be the movie critics? They could be, but they don't have to be.

2. Here is why option A must be true - What you've concluded isn't wrong. I agree there may be a snob who does not dislike hollywood blockbuster, but that's not what this option is about. The option starts with if someone is not a snob. Now if someone is not a snob, they definitely do not dislike hollywood busters (the question states - If someone dislikes Hollywood blockbusters, they are a snob). Consequently, if someone does not dislike Hollywood blockbusters, they like large explosions. So whoever is not a snob will definitely like large explosions as we know that the non-snobs cannot be the people who dislike hollywood busters.

Hope this helps you out!

Can someone please explain why E is wrong...

Hey Devil05, I'd be happy to, but would you mind telling me why you think E doesn't have to be true? The third sentence of the passage states - Most people who are over the age of fifty dislike Hollywood blockbusters. This sentence obviously implies that there are at least some people that dislike hollywood blockbusters and are over the age of 50.

ThanksBrian123,
I had chosen A over C and got it wrong.
This explanation of yours has definitely helped.

Thanks.
This explanation of yours, though not clear in first reading, helps to speed up thought process.
