Correct Response: A. Conversational repair strategies involve checking for understanding by asking clarifying questions. In the scenario, Student B could not understand what Student A was asking and did not demonstrate awareness of strategies for seeking clarification. Consequently, Student A became frustrated and angry with Student B. B is incorrect because the scenario does not indicate a pronunciation difficulty on the part of Student B. C is incorrect because the scenario provides evidence that Student B is able to take turns in a conversation, since Student B responds to each utterance made by Student A and gives adequate time for Student A to respond in turn. D is incorrect because Student A uses only simple sentence structures and verb tenses.
