Discussion Forum : Syllogism - Syllogism 1 (Q.No. 9)
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.

Option D is correct, because we have to consider all possibilities. And if a possibility doesn't satisfy, then it can't be true. Here, diagram 2 satisfies but diagram 1 doesn't. So, some cows are not elephants.

A valid conclusion must satisfy ALL the venn diagrams possible.
If u have two conclusions that satisfy one of the two given venn diagrams...then it'll be 'either 1 or 2'.
Hope this'll help u out a li'l...:)

If we follow with 2nd diagram opt:D is correct. If we follow 1st diagram opt:D is correct.
Post the correct procedure.
This makes confusion in answer.
But, everyone usually get idea of 1st diagram.

According to me answer a is correct one because in previous questions answer is dependent on any of the venn diagram that satisfies. Venn diagrams clears there is a possibility of the happening.

If we say that cow(A) is subset of crow(B) and, crow(B) is subset of elephant(C).
Then cow(A) will be subset of elephant(C) (if we do the venn diagram) .
Hence, only (1) conclusion follows.

Hence, only (1) conclusion follows.

Even using the first diagram option A is possible. Isnt' it?
Because Some cows are crows. And some crows are elephants. So there is a possibility of a cow can be an elephant. Right?

Hello,
According to me,
1st option is correct. It follows rule of transitivity in syllogisms.
Some cows - p.
Are crows - q.
Elephants - r.
p -> q.
q -> r.
p -> r.

I think so, option (A) is correct. If some cows are crows and some crows are elephants then, of course, some cows will be elephants. Can anyone justify how option (D) is correct?

A is the right option! though it is a possibility. We have to consider it! there is a possibility that some elephants cannot be crows! but we have to choose 1 as the option!

If both premises are particulars, then no valid conclusion can follow.
(eg. Some As are Bs
Some Bs are Cs
then it does not conclude that Some As are Cs)
(eg. Some As are Bs
Some Bs are Cs
then it does not conclude that Some As are Cs)
