Answer:
The sentence with a progressive verb aspect would contain a verb in the present participle form (-ing) and typically include words such as "am," "is," or "are" before it. For example, "I am running a marathon tomorrow" has a progressive verb aspect.
The sentence with a future-tense verb would contain a verb in the future-tense form and typically include words such as "will" or "shall" before it. For example, "I will run a marathon tomorrow" has a future-tense verb.
