According to syllogism rule: If on premises is -ve. Conclusion must be -ve.

So the conclusion 1 and 2 will be followed.
Devi said:   9 years ago
In both the statements, middle term exists twice so that conclusion must follow a particular. But one of the statement is negative conclusion must be negative. So, the conclusion is particular negative 4.

Some doors are not cats.

I think the Correct answer is 1, 2, 3.
Sindhu said:   8 years ago
The answer should be (1) (2) and (3) follow.

All the first 3 statements are correct. Door and Cat are disjoint sets (given).

Also Cat is the universal set of Dog (Dog is a subset of Cat). So all 3 are correct. Some cats are dogs but the vice versa is not true.
