Difficult Syllogism Solutions Answers

1.2; I follows by converting the first statement. Some notes are pencils (I) → conversion → Some pencils are notes (I) + Some notes are books = I + I = No conclusion. Hence II does not follow. Since III and IV form a complementary I-E pair, either of the two must follow.

2.3; Some cups are utensils + No utensil is a bucket = I + E = O = Some cups are not buckets. Hence I doesn't follow. No utensil is a bucket + All buckets are plates = E + A = O* = Some plates are not utensils. Hence neither II nor III follows. But since they form an I-E complementary pair, either of the two must follow. IV can’t be established.

3.5      4.4     15.1

6.1; Some boxes are balls + No ball is a bat (conversion of 2nd statement) = Some boxes are not bats [I + E = O]. Hence I follows and III does not. Now, Some spec- tacles are boxes and conclusion I give no conclusion. Hence II and IV do not follow.

7.3 ; Some bulbs are fans + All fans are tube lights = Some bulbs are tube lights....
(a) [I + A = I]. Now, statement (2) + (a) gives: Some tube lights are not pens. Hence conclusions I and II can’t be established. III follows from first statement on conversion. But IV does not. But I and II make a complementary pair [I-E pair]. Hence either I or II follows.

8.2      9.5

10.4; Only IV follows from statement (3) on conversion.
