Statement: The successful man has the ability to judge himself correctly. Assumptions:

  3. The successful man cannot make a wrong judgement.

A None is implicit

B All are implicit

C Only I and II are implicit

D Only II and III are implicit

E Only I and III are implicit

ANS:B - All are implicit

Explanation: Assumptions I and III directly follow from the statement and so both are implicit. Also, the basic quality of a successful man is that he can judge himself. This means that he need not judge others. So, II is also implicit.
