Question

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
1. All animals are rats.
2. No rat is brown.
Conclusions:
1. Some animals are brown.
2. Those animals that are not rats are brown,

A.

Both conclusions 1 and 2 follow.

B.

Only conclusion 2 follows.

C.

Neither conclusion 1 nor 2 follows.

D.

Only conclusion 1 follows.

Correct option is C

Given:
Statements:
1. All animals are rats.
2. No rat is brown.
Conclusions:
1. Some animals are brown.
2. Those animals that are not rats are brown.
Logic:
The least possible Venn diagram for the given statements is as shown below-
Conclusions:
1. Some animals are brown → False (AsAll animals are rats and No rat is brown so, Some animals are brown is false)
2. Those animals that are not rats are brown → False (As  All animals are rats and No rat is brown so, Those animals that are not rats are brown is false)
∴ Here, Conclusions I and II are false.
Hence, the correct answer is"Neither conclusion 1 nor 2 follows".
