(b) Only III follows

(d) Either III or IV follows

(e) None of these

Solutions:

1. Conclusion drawn from statements A and B is All thieves
are graduates.

Conclusion I is obvious from this sentence. III is obvious
from statement A. Also A + A + E = A + E = E.

So, Conclusion
drawn from all the three is No thieves are employed. II is obvious from this
sentence.

2. I follows from statements A and C. IV follows from
statements C and B. No other conclusion is possible.

3. Statements C + A gives Some cosmos are planets. So II is
valid. By aligning II and B or by aligning all the three statements, we get IV.

4. Conversion of A gives Some notes are books. Therefore I
follows. For II A and B are the relevant statements. But A + I – type pair has
no conclusion. So II is not valid. For III all the statements are relevant. No
definite conclusion can be obtained from this combination. But conclusions III
and IV form a complementary pair. Hence either conclusion III or conclusion IV
follows.

5. For I, A and B are relevant. But the conclusion obtained
here is Some cups are not buckets. So I is not valid. II and III form a
complementary pair. For IV, all the statements are relevant. But no conclusion
is obtained for this combination.
