Statements:
1. All actors are handsome.
2. John is handsome.
Conclusions:
I. John is an actor.
II. John is not an actor.
Which conclusion(s) logically follow?
A. Neither I nor II follows
B. Either I or II follows
C. Only conclusion II follows
D. Only conclusion I follows
Answer: Option B
Solution (By JKExamLibrary)
John is in the 'handsome' category, but we do not know if he is inside the 'actor' sub-category or outside it. Therefore, neither is definite. However, since he must either be an actor or not an actor, the 'either/or' condition applies.
Statement:
Only good singers are invited to the conference. Voice is a good singer.
Conclusions:
I. Voice is invited to the conference.
II. All invited people are good singers.
Which conclusion(s) logically follow?
Explanation:
The statement says 'only good singers are invited', which translates to 'All invited people are good singers' (II follows). However, it does not say *all* good singers are invited. Voice is a good singer, but might not be invited. Thus, I does not strictly follow.
