Question
Two statements are given followed by two conclusions
numbered I and II. 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: Some diaries are books. Some books are registers. Conclusions: I. Some registers are diaries. II. All registers are diaries.Solution
Some diaries are books (I) + Some books are registers (I) → No conclusion. Hence neither conclusion I nor II follow.
