Question

This question contains four arguments of three sentences each. Choose the set in which the third statement is a logical conclusion of the first two.

A. No sun is not white. All moon is sun. All moon is white.
B. All windows are open. No open space is allocated. All window is closed space.
C. No German can fire. All Americans bombard. Both, Germans and Americans can fight.
D. No X is Z. No Z is Y. No X is Y.

• A. A only
• B. B only
• C. C only
• D. D only

Hint:

In logical reasoning problems, make sure that the statements do not contradict each other and follow a consistent flow.

Answer 1

The Correct Option is A

Let's analyze each set:
- Option (A): "No sun is not white. All moon is sun. All moon is white." This follows logically. If all moons are sun and no sun is not white, then all moons must be white.
- Option (B): "All windows are open. No open space is allocated. All window is closed space." This creates a contradiction. It is not logically consistent.
- Option (C): "No German can fire. All Americans bombard. Both Germans and Americans can fight." This is contradictory as well.
- Option (D): "No X is Z. No Z is Y. No X is Y." This set also has contradictions that prevent it from being logically valid.
Thus, the correct answer is (1) A only as the third statement logically follows from the first two in this set.
Thus, the correct sequence is A only.
