According to figure there may be chance to occur "some watches are keys" then why did it go wrong.

According to figure 2 and 3 some watches are keys then why the conclusion 2 does not follow?
Ravinder kumar said:   1 decade ago
When one solves syllogism problems by Euler circles then a conclusion is true only if it is true in all possible diagrams i.e if a conclusion is not true in any one of Euler circle then it does not follow. Some watches are keys is not true in figure 1 so it does not follows.

Conclusion should be true in diagram 1 and 2, but conclusion does not follow in diagram 1, so how conclusion 2 true ?

I understand the three venn diagram but as per diagram-1 answer b is correct but if we use another diagram then we get another option also so how can we eliminate the another option or how can we take decision that which diagram is correct?
Preethi said:   1 decade ago
Yes, I too thinking that conclusion 2 is correct. If somebody got exactly the correct meaning, please explain it here

Why we draw 3 venn diagram ? if 1 diagram is able to answer the conclusion.
RAHUL SHUKLA said:   1 decade ago
We draw the possible vein diagram in every case. Here 3 cases are possible and statements must satisfy all three of them. If a single statement is not satisfied then it can't be true.

Thank You.
