Statements: 1. All books are useful. 2. Some useful things are expensive. Conclusions: I. Some books are expensive. II. All expensive things are useful.

1. Only I follows
2. Only II follows
3. Both I and II follow
4. Neither I nor II follow

Correct answer: Neither I nor II follow

Solution

From the statements, books are a subset of useful things, and some useful things are expensive. But there is no direct link between books and expensive things, so conclusion I does not follow. Also, we cannot say all expensive things are useful from 'some useful things are expensive', so conclusion II also does not follow.
