Discussion Forum : Syllogism - Syllogism 1 (Q.No. 11)
Directions to Solve
In each of the following questions two statements are given and these statements are followed by two conclusions numbered (1) and (2). You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusions and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.
Give answer:
- (A) If only (1) conclusion follows
- (B) If only (2) conclusion follows
- (C) If either (1) or (2) follows
- (D) If neither (1) nor (2) follows and
- (E) If both (1) and (2) follow.

Answer is correct. Although it may seem that from Venn diagram 2 the answer is not correct but its just an assumption that some dogs are bats as shown in the diagram 2. Because nowhere its mentioned that some dogs are bats or some bats are dogs. We have just assumed the probability that some dogs may be bats and vice versa. So we cannot conclude over that assumption. So the answer.

But both the conclusions are complementary pairs know so either nor won't come in the answer? please clarify my doubt.

Another way of seeing it.
In order for a syllogism to be valid, at least one of the two premises must contain a universal form. If both premises are particulars, then no valid conclusion can follow. For example, if "some cats are black" and "some black things are tables", it does not follow that "some cats are tables".

For an answer to be right, all the conditions must be satisfied, and for it to be wrong, one anomaly is enough.
For e.g. consider x/x..well, we may say x/x is 1, if x belongs to real numbers, but that is incorrect, since at x=0, 0/0 is not defined..since one value of x creates anomaly, thus we dont write x/x=1, for all x belongs to R.

Firstly we have to make Venn diagrams for all the possibilities which arise in the statements. Then jump onto conclusions and check whether the conclusions are true in all the diagrams. If yes, the conclusion follows. If it is not correct even in one case, that means that conclusion does not follow.
Rest all depends on practice.
Thanks

Ya please explain the correct approach towards such questions so that we can understand that what is the total number of venn diagrams needed in such questions?

Can anyone tell me that how can I figure out from problem that it contains or needs more than one venn diagram. Please.

Does that mean the answer is correct as long as it follows one of the venn diagrams?

Since here there is no relation shown between cat and dog in figure. Also a relation which is far is not exist.
