Question
Conclusions: I. No Ocean is a Sea. II.
Some Plateaus are not Oceans. Statements: In the question below some statements are given some conclusions followed by some statements. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read the conclusions and then decide which of the following statement is true for given conclusions.Solution
From Statement I. No Sea is a River (E) + Some River are Plateaus (I) → Some Plateaus are not Seas (O*) + Some Plateaus are Oceans (I) → No conclusion. Hence conclusion I does not follow. Some Plateaus are Oceans (I) → Conversion → Some Oceans are Plateaus (I) → Probable conclusion → Some Plateaus are Oceans (O). Hence conclusion II follows. From Statement II. Only River are Seas → All Seas are River and Seas can have negative relation with anyone. Hence conclusion I follows. Only a few Plateaus are Oceans → Some Plateaus are not Oceans (O). Hence conclusion II follows. From Statement III. All Seas are Plateaus (A) + No Plateau is a River (E) → No Sea is a River (E) + Some River are Oceans (I) → Some Oceans are nor Seas (O*). Hence conclusion I does not follow. No Plateau is a River (E) + Some River are Oceans (I) → Some Oceans are not Plateaus (O*). Hence conclusion II does not follow. From Statement IV. No Ocean is an Plateau (E) + A few Plateaus are Seas (I) → Some Seas are not Oceans (O*). Hence conclusion I does not follow. No Ocean is a Plateau (E) → Conversion → Some Plateaus are not Oceans (O). Hence conclusion II follows.
