Answer:
a. Valid, Modus Ponens
Step-by-step explanation:
The statement being made is an example of a valid, Modus Ponens. An example of modus ponens is when a premise is connected to a conclusion, and then either the premise or conclusion are true, then the other will be true too. For example, If today is Monday, then Ava will go watch a movie. Today is Monday. Therefore, Ava will watch the movie. This same form of logic applies in this scenario, since swimming and snowing are tied together and one turns out to be true then the other is true as well.
