Three statements are given followed by three conclusions
numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: All animals are forests. Some domestics are forests. Some domestics are trees. Conclusions: I. Some trees are animals. II. Some forests are animals. III. Some forests are trees.Solution
Some domestics are forests (I) + All animals are forests (A) → Conversion → Some forests are animals (I) → No conclusion. Hence conclusion I does not follow but conclusion II follows. Some domestics are forests (I) → Conversion → Some forests are domestics (I) + Some domestics are trees (I) → No conclusion. Hence conclusion III does not follow.
