Can you describe how No dog is rat is not satisfied? Please describe.

But I think that all the three conclusions are correct because a/q to the case of minimum overlapping; We will consider only the 1st Venn diagram.

Conclusion : Some cows are not cats.

No cow is rat. Obviously this statement is true. Then answer will be 1 and 3.

No cow is rat. Is it right or not?

According to the statement all the three statements are true, but when we think logically,
Assume that:
Some cows are cat.
Some dogs are rat.
First 2 statements are false and 3rd statement is true.
So first and second statements can be either case but the 3rd statement is true.
So only 3 follows.
We should think all possible ways.

The conclusion has to satisfy all possible venn diagrams.

Just explain How "No cow is cat" not follows ? According to first diagram Cow is not related to anything. We have clear statement in the questions, on which we have to give answer. So how can you make your own assumptions/Possibility (Which is not stated in the question) ? If you can then can I make statements like all cows cat ?

In order for the conclusion to be true, it should satisfy all possible probabilities. So you have to draw all possible venn diagrams and see if the conclusion is satisfying all of them. It is a conclusion if it satisfies all scenarios. If it doesn't then it is a probability and not a conclusion. So in the above problem, Conclusion No.3, "Some cats are rats" is the only conclusion which satisfied both the scenarios.
Hope this helps.
