Correct Response: C. Language acquisition research suggests that learners who take risks and are eager to integrate into a new culture often acquire language faster than learners who are not risk takers in relation to attempting to use a new language. A is incorrect because not being afraid to try to communicate does not necessarily mean that the student is able to self-monitor his language production or to internalize language rules. B is incorrect because, while the precise causes of fossilization are unknown, there is no evidence in the research that indicates outgoing people are more likely to experience fossilization than less outgoing people. D is incorrect because the student's outgoing personality is more likely to reduce social distance between him and his peers, regardless of their personalities.
