PrepTest 77, Section 3, Question 25
Many conceptual categories are parts of dichotomous (distinct and mutually exclusive) pairs: good or bad, right or wrong, rational or irrational, etc. However, advances in scientific understanding have shown some long-held dichotomies to be untenable.

The longer fruit is kept, the more likely it is to become rotten. While these peaches seem to be fine, they have been kept for a rather long time. So it is best to throw them away now before they begin to rot.
