Here is the sentence:

Marsha sat at the dining room table, wondering [and worrying] what dish her husband might serve. Brent's refusal to use measuring devices ment that her tongue either leapt in surprise at the excessive seasoning or lay in her mouth, bored with the bland taste.

The first verb, ment, is the problem. As you know, the sentence requires the simple past. Meant is the correctly spelled form.
