Consider the 4th option again please.

D Shareef said:   1 decade ago
Bala 4th option is not correct. Because all whites are not blue. Only some.
(1)

But how can the 1st option b correct. Middle term is appearing in the conclusion.

M.saiadithya said:   1 decade ago
Precisely, the middle term is distributed more than once so how can this be correct ?

Pranjali said:   1 decade ago
The option no 1 & 3 is the answer.

Comparing sentence 1 & 2 - All green are white.

After the conversion of both sentences (1 & 2) its become.

1. Some blue are green.
2. Some white are blue.

Well, (1) is obviously correct (4) is obviously not. But I could not decide whether I should pick 2 or 3. In accordance with venn diagram - both seemed to be correct.(white could either "touch" green and, thus, blue) or touch only blue - maybe I did something wrong) initially I thought
so I had to make AAI-4 scheme which showed that (2) was a right option.
