Concept:Use logical deduction from given statements. No assumptions beyond the stated facts are allowed.
Explanation:Some students are clever, and all clever people are honest. So the group of students who are clever is a subset of honest people. Hence, some students are honest — conclusion (1) is true.
No direct link exists between students and lazy people. The statements do not say anything about all students. So conclusion (2) is false.
All clever people are honest, and no honest person is lazy. Therefore, all clever people are also not lazy. Since some clever people exist (from statement 1), some clever people are definitely not lazy — conclusion (3) is true.
All students are honest? No. Only some students are honest. It is possible that every honest person is a student. So we cannot say that some honest people are not students — conclusion (4) is not definitely true.
Answer:Only (1) and (3) follow. Option D.
