The argument starts with what it calls a "crude" generalization: words ending in -ee refer to people who are affected by, or the objects of, a particular action performed by someone else. As a counterexample, the argument proposes the term "absentee," which, if anything, seems to refer to the person doing the "absenting," not to the recipient of someone else's action. Because of this counterexample, the author proposes a more specific rule: a word ending in -ee refers to the person affected by someone else's action if it refers to one party in a two-party transaction.

The argument proceeds by presenting a general rule, then by providing a counterexample that undermines the rule. Based on the counterexample, the author refines the rule to apply it to a more limited set. The idea of words ending in -ee describing the person affected by an action performed by someone else isn't true in all cases, only in those cases where the action involves a two-party transaction.

In the "absentee" example, there isn't a two-party transaction going on like in the other examples the author provides. The "absentee" is the person absenting themselves, not absenting someone else, while the employee is employed by an employer, the payee is paid by a payer, etc. Thus, "absentee" falls outside the set of two-party transactions where the author's more refined rule applies. The question stem asks us to look for another word that works the same way: a word that, because it doesn't refer to one party in a two-party transaction, works as a counterexample to the generalization the author initially provides.
