A sequence of two related utterances by two different speakers. The first utterance leads to a set of expectations about the response.

• A. Adjacency pair
• B. Turn-taking sequence
• C. Dialogue
• D. Exchange pair

Answer: (A)

The concept being tested is adjacency pair. In conversation analysis, two adjacent turns by two different speakers form a unit where the first turn prompts a conventional response from the second. The first utterance—whether a question, greeting, offer, or request—sets up an expectation for the specific kind of reply that typically follows and completes the action of the exchange. Because the second speaker’s response is shaped by what was said first, these pairs are tightly linked and occur in immediate succession without intervening turns. For example, a question invites an answer, a greeting invites a reply, and so on; the pairing is what gives the interaction its predictable flow.

While other terms touch on parts of conversation, they don’t pinpoint this precise pairing. A turn-taking sequence describes who speaks when more broadly, not the tight two-part unit that responds to the first utterance. Dialogue is the overall exchange, not the specific two-turn structure. An exchange pair isn’t a standard term for this phenomenon, so the defining feature here is the adjacency pair.
