In this question two statements are given, 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 conclusions and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.
Statements: (1) Some phones are watches.
(2) All watches are guns.
Conclusions:
I. All guns are watches.
II. Some guns are phones
  1. if only conclusion I follows
  2. if only conclusion II follows
  3. if either I or II follows
  4. if both I and II follows

Answer and explanation

Correct answer: B - if only conclusion II follows
Some phones are watches and all watches are guns, so some phones are guns, i.e. some guns are phones (II). 'All guns are watches' is an illicit conversion, so I does not follow.
