Statement: The train is running late by 2 hours. Conclusions: I. It will reach the destination at the scheduled time. II. Passengers will have to wait.
A. Neither I nor II follows
B. Only I follows
C. Both I and II follow
D. Only II follows
Answer: Option D
Solution (By JKExamLibrary)
I contradicts the statement. If the train is late, passengers waiting for it will have to wait, so II follows.
Statements:
1. No lock is a key.
2. No key is a door.
Conclusions:
I. All locks are doors.
II. Some doors are locks.
Which conclusion(s) logically follow?
Explanation:
Two negative premises yield no positive conclusion between the unconnected terms (locks and doors). They might overlap, or they might not. Neither conclusion is definite.
