Statements:
Some students are clever.
All clever people are honest.
No honest person is lazy.
Conclusions:
(1) Some students are honest.
(2) No student is lazy.
(3) Some clever people are not lazy.
(4) Some honest people are not students.
Only (1) and (3) follow
To determine which conclusions logically follow from the given statements, we need to analyze how the information provided in the statements relates to each of the conclusions. Let's look at the statements and conclusions one by one:
Statements:
- Some students are clever.
- All clever people are honest.
- No honest person is lazy.
Conclusions:
- Some students are honest.
- No student is lazy.
- Some clever people are not lazy.
- Some honest people are not students.
Now, let's evaluate the conclusions:
- Some students are honest.
Given that "Some students are clever" and "All clever people are honest," it logically follows that some students are honest. Therefore, conclusion (1) follows. - No student is lazy.
The statements do not provide enough information to conclude that no student is lazy. While clever students are honest and no honest person is lazy, it doesn't mean every student falls into this category (some students could be neither clever nor honest). Therefore, conclusion (2) does not necessarily follow. - Some clever people are not lazy.
Since all clever people are honest and no honest person is lazy, it follows that all clever people are not lazy. Therefore, conclusion (3) logically follows. - Some honest people are not students.
While the statements specify that some students are clever and thus honest, there is no information on whether all honest people must also be students. Therefore, conclusion (4) does not necessarily follow based only on the available information.
Conclusion:
The conclusions that logically follow from the given statements are (1) Some students are honest, and (3) Some clever people are not lazy. Therefore, the correct answer is "Only (1) and (3) follow."
