Question
Statements: Some flower are stem. Some stem
are root. Each root is plant. Conclusions: I. All stem are plant is a possibility. II. Some flower are root. III. Some plant are flower. In the question below there are three statements followed by three conclusions I, II and III. You have to take the three 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 three statements disregarding commonly known facts.Solution
Some stem are root (I) + Each root is plant (A) → Some stem are plant (I) → Conversion → Some plant are stem (I) → probable conclusion → All stem may be plant (A). Hence conclusion I follows.
Some flower are stem (I) + Some stem are root (I) → No conclusion. Hence neither conclusion II nor III follow.
