If the statements above are true, each of the following must also be true EXCEPT:
A. Some shy people are extroverts.
B. Some shy extroverts are not actors.
C. Some exuberant people who are actors are shy.
D. All people who are not extroverts are not actors.
E. Some extroverts are shy.
to me all seems valid:-(
how to solve this one.
A.Incorrect. "Some shy people are extroverts." The passage claims that there are shy actors. Because all actors are extroverts then a shy actor is also an extrovert.
B.Correct. "Some shy extroverts are not actors." One of the main points stated by the passage is that ALL actors are extroverts. Therefore, the claim that a shy extrovert is not an actor contradicts the explicit statement that ALL actors are extroverts. Lets also note that "shy" is not the same thing as "introverted," which means that part of the confusion of this question stems from failing to understand that a person can be a "shy extrovert" but cannot be an "introverted extrovert" because the latter is contradictory. This way, you can read "Some shy extroverts are not actors" as "Some extroverts are not actors", a statement that clearly contradicts the passage given the scope of the information with which we are working.
C.Incorrect. "Some exuberant people who are actors are shy." The passage makes clear that there can be "shy extroverts", and because "All actors are exuberant people and all exuberant people are extroverts," it follows that some exuberant people who are actors will be "shy extroverts"
D.Incorrect. "All people who are not extroverts are not actors." The statement is supported by the passage because the passage makes clear that all actors are extroverts.
E.Incorrect. "Some extroverts are shy." The passage makes clear that extroverts can be shy because being shy is not the same thing as being introverted. Thus, in order to effectively answer this question, we have to be attune to this type of intricate word play that substitutes a similar meaning word for words that have more specific meanings, such as the use of "shy" in place of "introverted."
I hope that is clear,
