why can't all men who are vertebrates, also be mammals? In my opinion, there are three possibilities, not two.

Third possibility is that no mammals can be vertebrates or men.

What about the possibility of some men are mammals?

Puneetsingh said:   9 years ago
All men are mammals also be true answer.

Sir I didn't understand the 2nd diagram. Here we can't tell that some mammals are men too. That not given in statement. As I know that we can't think anything extra that's not given. Is it a case of possibility ?

Where & how to use all+some = No conclusion.

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.

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

Sumair said:   9 years ago
There should be three diagrams, all mans are mammals can be true if the diagram of circle of mammal in diagram 2 is increased.

@ 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.
