Logical Deduction - Verbal and Reasoning

Directions to SolveIn each of the following questions, two statements are given followed by three or four conclusions numbered I, II, III and IV. You have to take the given statements to be true even if they seem to be at variance from the commonly known facts and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.
Q1:

Statements: Some clothes are marbles. Some marbles are bags. Conclusions:
  1. No cloth is a bag.
  2. All marbles are bags.
  3. Some bags are clothes.
  4. No marble is a cloth.

A Only either I or IV follows

B Only either I or II follows

C None follows

D Only either I or III follows

ANS:D - Only either I or III follows

Explanation: Since both the premises are particular, no definite conclusion follows. However, I and III involve only the extreme terms and form a complementary pair. Thus, either I or III follows.
