• Only 4

Answer 1

Only 2

Explanation:

(1)

From the above diagram, we cannot conclude that all stars are red because no star is red.

(2)

Clearly, all doors are not outdoors.

(3)

In the given statements 'No Japanese can fire' and 'all Chinese are books' there is no relation between Japanese and Chinese. So, we cannot say that the Japanese and Chinese can fight.

(4)

So, we cannot say that 'No A is C'.
