Quizplus · Accepted Answer

The argument commits a fallacy by assuming that knowing one fact about a person (John Glenn being a senator) automatically means knowing another fact (John Glenn being an astronaut), without any logical connection established between the two facts. This is an invalid inference, not a warranted or relevant one, nor is it circular or necessarily worthy of acceptance based on the premises given.
