Direction: In each question below are given two/three statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements, disregarding commonly known facts. Give answer

Statements:     Some oceans are lakes.

Some ponds are rivers.

All rivers are lakes.

Conclusions:

I. All corridors being corners is a possibility.

II. Some lakes are not ponds is a possibility.

A)  if only conclusion I follows.

B)  if only conclusion II follows.

C)  if either conclusion I or II follows.

D)  if neither conclusion I nor II follows.

E)  if both conclusions I and II follow.

Correct Answer: E

Solution :

Some ponds are rivers (I) + All rivers are lakes  = I + A = I = Some ponds are lakes It means Some lakes are not ponds is a possibility. Hence, conclusion II follows. Again, Some oceans are lakes  conversion Some lakes are oceans. Now, All rivers are lakes  + Some lakes are oceans (1) = A +1 = No conclusion, but a possible positive relation exists between 'river' and 'ocean'. Thus, conclusion I follows.
