In the following question, two statements are given followed by four conclusions. Taking the given statements to be true, decide which of the given conclusions logically follows from the given statements:
Statements:
Some rivers are plateau. No plateau is mountain.
Conclusions:
Explanation:
Since Some rivers are plateau, it definitely follows that Some plateau are rivers. Hence, conclusion I follows. This eliminates option 2.
Now, No plateau is mountain. However, that does not mean that the sets of rivers and mountain have to intersect with each other. Hence, conclusions II and IV may or may not follow. This eliminates option 4.
Now, any river that is a plateau cannot be a mountain (as No plateau is mountain). Hence, there are definitely some rivers that are not mountains i.e. conclusion III follows.
Hence, option (c).
