Answers–
1. (e) Both the conclusions are immediate inferences drawn from Statements 1 and 2 and follow from the rule of conversion.
2. (d) Both the conclusions are mediate inferences. A + I = No result. Therefore, no conclusion can be drawn. Moreover, the pair of conclusion is not a complementary pair. Hence, none of the conclusion follows.
3. (e) A + E = E. Hence, conclusion “No pencil is a book” follows. Conclusion II is an immediate inference drawn from Statement 1.
4. (d) None of the conclusions follows.
5. (d) A + I = No result. Hence, on conclusion follows.
6. (a) A + A + A. Hence, conclusion I follows.
7. (d) A + E = E. Hence, none of the conclusions follows.
8. (e) Both the conclusions follow.
9. (a) A + E = E. Hence, Conclusion I follows.
10. (a) A + A = A, hence X has a sunset point.
11. (c) Conclusions make a complementary pair.
12. (d) A + I = No result.
13. (a) “Some machines are fools” — “Some fools are machines”.
14. (d) A + I = No result. Hence, none of the conclusions follows.
