Final answer:
The situation with Mr. Leonzo's class demonstrates deductive reasoning, where a general class policy is applied to a specific case leading to a conclusion consistent with the initial rule.
Step-by-step explanation:
The situation described by the student involves Mr. Leonzo communicating a general rule to the class, which is that no credit will be given to assignments that show no work. The student observes this rule in practice over two months by doing homework and seeing that credit is given when work is shown. However, when the student submits an assignment without showing work, they receive no credit. This scenario is an example of deductive reasoning. Deductive reasoning starts with a general rule or premise (in this case, the class policy stated by Mr. Leonzo) and applies it to a specific case to reach a logical conclusion. The conclusion in this case is that the student did not receive credit for the homework because it lacked the required work shown.
