The correct answer is C, that means that conclusion 1,2, and 4 are wrong.

Conclusion 1 " all men are mammals," and 2 "all mammals are men," are the same in this context. They are wrong because they do not agree with the statements "All men are vertebrates. Some mammals are vertebrates." If all men were mammals, then not some, but all mammals were vertebrates. That is not the case.

Option 4 is also correct. Because all men are vertebrate simultaneously all vertebra are men.

Middle term cannot be present in the conclusion.

All + some = some,
Some men are vertebrates,so in this sentence, both are not distributed and middle term = vertebrates are also not distributed. So the answer is no conclusion.

If you have particular statement common, we cannot draw any conclusion.

Neetu said:   8 years ago
I have to ask a little clarification.

Conclusion : Some men are vertebrates.

This conclusion is true or false, please explain your answer.

@ SUPRAJ.

-UNTIL the STATEMENT is given that some men are mammals or all men are mammals or vice versa. We cannot conclude the CONCLUSION to be correct.

There should be three diagrams, all mans are mammals can be true if the diagram of circle of mammal in diagram 2 is increased.

Why "all men are mammal" isn't correct?

Hello @Anki,

Here terms are "All men" and "Some Mammals" and they will always give no conclusion as they represent different categories. Solve Syllogism problems (including possibility type) in few seconds.
