Correct Answer: Neither conclusion I nor II follows
Solution :
The possible Venn diagram for the given statements is as follows –
Let's analyse the conclusions –
Conclusion (I):
Some rats are cats – From the above diagram, it is clear that there is a negative relation between rats and cats. So, this conclusion doesn't follow.
Conclusion (II):
Some dogs are rats – From the above diagram, it is clear that no cats are rats, and the circle of dogs is completely inside the circle of cats. So, this conclusion doesn't follow.
So, neither conclusion I nor conclusion II follows. Hence, the first option is correct.
