No, /, therefore,/ is an invalid argument. B. No, /, therefore, / is an invalid argument. C. Yes, /, therefore, / is a valid argument. D. There is not enough information to determine.

Answer 1

The statement is invalid. The argument structure used in the statement is affirming the consequent, which is an invalid form of reasoning.

Step-by-step explanation:

The statement is invalid. The argument structure used in the statement is affirming the consequent, which is an invalid form of reasoning. Affirming the consequent states that if X, then Y. Y is true. Therefore, X is true. However, this form of reasoning is invalid because there could be other reasons why Y is true. In this case, there could be other reasons why Eric doesn't go to bed early tonight, such as having plans or not feeling tired, which do not necessarily mean it is not a school night. Therefore, Option A, No, therefore, is an invalid argument, is the correct answer.
