Question
Statements: Some summers are winters. Some
seasons are autumns. No winter is a season. Conclusions: I. Some summers are autumns. II. Some autumns are not winters. III. All summers are seasons. In the question below there are four statements followed by three conclusions I, II and III. You have to take the four given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the four statements disregarding commonly known facts.Solution
Some summers are winters (I) + No winter is a season (E) → Some summers are not season (O) + Some seasons are autumns (I) → No conclusion. Hence neither conclusion I nor III follow. No winter is a season (E) + Some seasons are autumns (I) → Some autumns are not winters (O). Hence conclusion II follows.
