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:
No girl is a horse.
Rachel is a girl.
Conclusions:
I. Rachel is not a horse.
II. All girls are not Rachel.
Option 1: Both conclusions I and II follow
Option 2: Neither conclusion I nor II follows
Option 3: Only conclusion I follows
Option 4: Only conclusion II follows
Correct Answer: Only conclusion I follows
Solution : The possible Venn diagram according to the given statement is as follows –
Let's analyse the conclusions –
Conclusion I:
Rachel is not a horse – From the Venn diagram, it is evident that Rachel is a girl and no girl is a horse. Thus, it can be concluded that Rachel is not a horse.
Conclusion II:
All girls are not Rachel – It is a possibility that some parts of the circle representing the girl are not overlapped by the circle representing Rachel. But this is not definite. Thus, this conclusion does not follow.
So the only conclusion I follows. Hence, the third option is correct.
