Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

<br>

Statements:

All furs are rabbits.

All furs are plants.

<br>

Conclusions:

(I): Some rabbits are plants.

(II): All plants are furs.

  1. ((a))

    Neither conclusion (I) nor (II) follows

  2. ((b))

    Only conclusion (I) follows

  3. ((c))

    Only conclusion (II) follows

  4. ((d))

    Both conclusions (I) and (II) follow

Show Answer
Answer: ((b))

Only conclusion (I) follows

The least possible Venn diagram is as follows:

Conclusions:

(I): Some rabbits are plants.- True (All furs are rabbits.All furs are plants.Some rabbits are plants is True)

(II): All plants are furs.- False (All furs are plants.So,All plants are furs is may be possible but not definite Hence, it is false)
