Answer 1

The underlined portion "offer" should be changed to "offer;" to correct the run-on sentence. The revised sentence would be:

"Thomas chewed his sandwich deliberately, contemplating her offer; he opened his notebook to share a calculus problem he’d been working on."

So, the answer is:

offer;
