MERGING CONCEPT.

This concept is applicable when more than one conclusion does not follows.

Rules :

The two non-following conclusions must be of the same character.

One conclusion must be positive (All/Some).

One conclusion must be negative (No/Some-not).

By this, the answer should be either 3 or 4. Am I correct or wrong please explain.
