"In cases where the Exchangers involved in a conversation are construed as two separate groups with different levels of volitionality or control, Exchanger_2 refers to the semantically and grammatically less prominent group. It is generally encoded within a prepositional phrase (e.g. headed by with). Note that it is possible for a single role to correspond to multiple referents. For example, if the prepositional object in the example below were plural, we would still assign it the single role Exchanger_2. The trade with Cuba went exactly as planned."@en . . "ex2" . . . .
