Question
Statements: No door is a window. Some
windows are stems. Only few stems are roots. All roots are handles. Conclusions: I. All stems being roots is a possibility. II. Some handles are windows. III. All stems not being doors is a possibility. In the question below are given some statements followed by some conclusions. You have to take the given statements to be true even if they seem to be in variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.Solution
Only few stems are roots →  Some stems are roots (I) and Some stems are not roots (O). Hence conclusion I does not follow. Some windows are stems (I) + Some stems are roots (I) → No conclusion. Hence conclusion II does not follow. No door is a window (E) + Some windows are stems (I) → Some stems are not doors (O*) → Probable conclusion → All stems may not be doors (I). Hence conclusion III does not follow.
