Question

Explanation:

To determine why Shane says Avery should be grateful, we analyze each option. The first option states Shane is heading to the army soon and won't be around to interrupt or annoy her, which provides a reason for gratitude. The other options (separate bedroom, not throwing a sock, chore distribution) don't align as closely with a reason for Shane to say she should be grateful in a context likely related to his departure.

Answer:

A. because he is heading off to the army soon and won't be around to interrupt or annoy her
