Question
In the question below, three statements are given
followed by the conclusions. You have to take the given statements to be true even if they seem to be at 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. Statements: All Umbrellas are Clouds. Only a few Clouds are Streets. All Streets are Rain. Conclusions: I. Some Umbrellas are Streets II. No Umbrella is a StreetSolution
All Umbrellas are Clouds (A) + Some Clouds are Streets (I) → No conclusion. Hence neither conclusion I nor II follow but it will make a complementary pair. Hence either conclusion I or II follow.
