Concept:In syllogism, "All
A are
B" implies "Some
A are
B", but "Some
A are
B" does not imply "Some
A are not
B".
Explanation:Let
M denote Men,
G denote Good,
B denote Boys, and
D denote Bad.
Statement I: All Men are Good, so
M⊆G.
Statement II: Some Boys are Bad, so
B∩Dî€ =∅.
Statement III: Few Bad is Good means Some Bad are Good, so
D∩Gî€ =∅.
Conclusion I: Some boys are not bad → False, because knowing "Some boys are bad" does not guarantee that any boy is not bad.
Conclusion II: Some men are good → True, because all men are good, so at least some men are good.
Conclusion III: Some bad are not good → False, because knowing "Some bad are good" does not guarantee that any bad is not good.
Thus, only conclusion II logically and definitely follows.
Answer:Option B. Only conclusion II follows.
