Question : Directions: Two statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
Some horses are not trucks.
All horses are white.
Conclusions:
I. Some white are trucks.
II. Some horses being trucks is a possibility.
Option 1: Only conclusion I follows
Option 2: Neither conclusion I nor II follows
Option 3: Only conclusion II follows
Option 4: Both conclusions I and II follow
Correct Answer: Only conclusion II follows
Solution : According to the given statements, the Venn diagram is –
Let us analyse the conclusions –
Conclusion I:
Some white are trucks – It is a possibility that the circles representing white and trucks overlap and have a part of their area in common. But this is not definite. So, this conclusion doesn’t follow.
Conclusion II:
Some horses being trucks is a possibility – It is a possibility that the circles representing horses and trucks overlap and have a part of their area in common. But this is not definite. So, this conclusion follows.
So, only conclusion II follows. Hence, the third option is correct.
