(You must provide an answer before moving to the next part.)a. modus tollens b. hypothetical syllogism c. modus ponens d. disjunctive syllogism

Answer 1

Answer:

c. modus ponens

Explanation:

In propositional logic, we learn that modus ponens is a valid argument and a rule of inference. Modus ponens states that "P implies Q, and if P is true, then Q must be true."

Based on these propositions, we learn that all food that is healthy does not taste good, and tofu is healthy. Therefore,

If all food that is healthy does not taste good,

and tofu is healthy to eat,

then tofu does not taste good.
