Answer:
The correct answer is 1. incomplete comparison.
Explanation:
In the example, there can certainly exist a logical relation between the two propositions (inquisitive students - make - better students), however, since there is not enough information, a logical relation between them cannot be properly constructed. If the comparison presented some sort of argument then it would be complete. For instance: "Inquisitive children, <em>since they are more curious and open to learning</em>, make better students". Without the argument, the idea seems more like an unsustained opinion, based on prejudice, than anything else.
