Hi,

** **Statements:a. Some boys are scholars b. Some teachers are boys c. All scholars are observes Conclusions:1. Some scholars are boys 2. Some scholars are not boys 3. Some observers are boys 4. Some teachers are scholars Answer:A. 1, and 3 follow B. 1, 3, and 4 follow C. Either 1 or 2 and 3 follow D. None of the above

Logic behind the answer:

(i) At any given time only 2 statements can be used to make a conclusion(Otherwise there will be fallacy of 4 or more terms). So let us take the first two statements.

a. Some boys are scholars b. Some teachers are boys

For this case __no conclusion__ exists as both the statements are 'particular'.

(ii) Let us take statements a and c:

a. Some boys are scholars c. All scholars are observes

Since these statements do not create any fallacy, a conclusion is posible. The __conclusion is 'Some observers are boys'.__

(iii) Let us take statements b and c:

b. Some teachers are boys c. All scholars are observes

These statements create fallacy of 4 terms, so __no conclusion__ is possible.

So all the above analysis: Our only conclusion is that __Some observers are boys. (Given 3rd conclusion)__

But on closer analysis of the given 1st conclusion we can see that it is but same as the 1st statement. Since 1st statement is taken to be true, 1st conclusion is also true.

So final list of possible conclusions: 1st and 3rd conclusions
