Is the answer 'D'?

can u plz explain

[abhishekit]

I think it should be 'B'.

I will think of it as a 'set' problem. Let one circle be of all Actors. This will lie within a circle of Exuberant. Both these circles will lie within the circle of Extroverts.

Now a part of the smallest circle, actor circle, can be labeled as 'S' for shy. We don't have enough information to draw the second part of Shy people. For now, you can just visualize it as outside the three extroverts circle but with a possibility of crossing in.

Now if you look at choices -
1. Definite yes.
2. May be. As I said, we don't have enough info to draw the second set of shy people (who are not actors).
3. Definite yes.
4. Definite yes
5. Definite yes.

Agree with B. (missed the EXCEPT originally at 1am :)

I agree with abhishekit. Correct Answer is B. This is basically a questions of Syllogisms - where premises are given and correct conclusion needs to be figured out from the answer choices.

Interesting question, and I too prefer abhishekit's method of drawing circles.

Just so you know, this question type doesn't really appear on the GMAT. It's more of an LSAT type.
