Question

In each group of questions below are 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 and then decide which of the given conclusions logically follows from the two/three statements, disregarding commonly known facts. Give answer
Statements: Some trees are plants.
All bushes are plants.
Conclusions: I. Atleast some trees are bushes
II. Some trees are definitely not bushes

• A. if only conclusion I follows.
• B. if only conclusion II follows.
• C. if either conclusion I or conclusion II follows.
• D. if neither conclusion I nor conclusion II follows.
• E. if both conclusion I and conclusion II follow.

Answer 1

Answer: (C)

if either conclusion I or conclusion II follows.

The statements given in the question can be summed up through the above Venn diagram.

There can be two cases according to the statements.

So, In the first case, there will be some trees which are bushes. In the second case, no trees are bushes.

Now, if we observe the both conclusions, it is clear that they are complementary cases i.e one of them must be true.

Hence, either conclusion I or conclusion II follows, which means Option C is the correct answer.
