Logical Deduction

Directions to SolveIn each question below are given two statements followed by two conclusions numbered I and II. You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusion and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.Give answer:
  • (A) If only conclusion I follows
  • (B) If only conclusion II follows
  • (C) If either I or II follows
  • (D) If neither I nor II follows and
  • (E) If both I and II follow.

Q1: Statements: All men are dogs. All dogs are cats. Conclusions:
  1. All men are cats.
  2. All cats are men.

A Both I and II follow

B Only conclusion I follows

C Neither I nor II follows

D Only conclusion II follows

E Either I or II follows

ANS:A - Only conclusion I follows

Explanation: Since both the premises are universal and affirmative, the conclusion must be universal affirmative. However, conclusion II, being an A-type proposition, distributes the term 'cats'.

Since the term 'cats' is distributed in II without being distributed in any of the premises, so conclusion II cannot follow. Thus, only I follows.
