Syllogism

Concept:Syllogism — deducing logical conclusions from given statements.Explanation:The first statement is "All students in my class are intelligent."This means if someone is a student in my class, then that person is intelligent.The second statement is "Rohit is not intelligent."If Rohit were a student in my class, he would have to be intelligent (from the first statement).Since he is not intelligent, he cannot be a student in my class.Thus, conclusion I ("Rohit is not a student of my class") logically follows.Conclusion II ("Rohit must work hard") has no basis in the given statements, so it does not follow.Answer:Only conclusion I follows.
