Hi RS1, thanks for the question.

We get the following from the passage:

Actor -> Exuberant -> Extrovert

Shy <-some-> Actor

We can combine all of this to be:

Shy <-some-> Actor -> Exuberant ->Extrovert

B is correct because it is not firmly supported that some Shy extroverts are not actors. What some represents is at least one, so it could possibly be that all shy people are actors. It doesn't have to be true that some are not.

I hope this helps. Please let me know if you have any other questions.
