Statements:
1. Some scientists are philosophers.
2. All philosophers are writers.
Conclusions:
I. Some writers are scientists.
II. All scientists are writers.
Which conclusion(s) logically follow?
A. Neither I nor II follows
B. Only conclusion II follows
C. Both I and II follow
D. Only conclusion I follows
Answer: Option D
Solution (By JKExamLibrary)
The scientists who are philosophers must also be writers because all philosophers are writers. Therefore, some writers are scientists (Conclusion I). We cannot say all scientists are writers based on the given premises (Conclusion II).
Statement: On metro section of railways, the motormen are frequently required to do overtime during May and June though all vacancies are completely filled as per requirement of this section.
Conclusions:
I. Many motormen take leave of shorter or longer duration during this period.
II. Some motormen desire to earn overtime whenever possible.
Explanation:
Neither conclusion follows. Overtime could be due to increased workload, not necessarily leave. The statement does not discuss motormen's desire to earn overtime.
Explanation:
I is a generalization. II is already given ('the school bus'). Neither new conclusion is drawn; both restatements or generalizations. Usually such questions: I does not follow (all). II is just repeating. So neither.
