(1) Club B has 16 members. (2) Exactly two people from Club C are also members of Club A.
Kudos for a correct solution. VERITAS PREP OFFICIAL SOLUTIONCorrect Answer: B Explanation: (1) It is possible that the 11 members of Club A who belong to Club B include the 5 members who also belong to Club C. It is also possible that no one who belongs to Club A also belongs to Club C. Accordingly, statement 1 is insufficient. (2) This statement answers the question directly, indicating that two people are members of both Club A and Club C. Accordingly, this statement is sufficient. Since statement (2) alone is sufficient to answer the question, the correct answer is B.

Does Statement 2 comprises of both common between A & C and common among A, B, & C. By the term exactly, I understood as if they are just common between A & C and since we do not know those who are common among all three clubs the information is insufficient; and hence Answer is E.

(1) Club B has 16 members. (2) Exactly two people from Club C are also members of Club A.
Kudos for a correct solution. This question asks us if we have enough information to determine how many members of club A are also member of club C it is important to note that conditional logic doesn't necessarily apply in set theory in other words, we if know how many members of club C are also members of club A then we know how many members of club A are members of club c. If this were critical reasoning, for example, then the argument if all A are B then all B are A would be fallacious ( All humans are mammals but not all mammals are humans). Though if you look at this scenario on a three circle venn diagram you can see that whatever numbers falls into the intersection of Group A and C ( the circle that intersects those groups) this number applies both ways. Statement (1) tells us the size of club B which in itself does not allow us to find the number of members in club C. Insufficient Statement (2) answers the question. Sufficient.

From St1, we don't know the number of members of club A in C. It may or may not be an overlapping set. From St2, Its the other way of projecting the answer. If exactly 2 from Club C are present in Club A, the same is true in viceversa.
So ans is B.

Exactly, language is imprecise and hence there gotta be an inference to solve the question... Veritas' inferece is that AuC excludes B, we (cause I made the same inference) is that not necessary does, because the problem doesn't says so... I've find Veritas practice kinda annoying because of that
