This question is missing the options. I've found the complete question online. It is as follows:
As part of a tenth-grade "Social Living" course, a teacher has a guest speaker come to his classroom to talk about the dangers of drug use. The guest speaker is a former drug dealer and hardcore drug user, who became involved in crime as a result of his connection to drugs, spent many years in jail, later entered a drug rehabilitation program, and finally cleaned up his act. Social psychologists would refer to this kind of communicator as a(n) ____.
a. sleeper source
b. convert communicator
c. normative communicator
d. implicit source
Answer:
I believe the correct answer is letter b. convert communicator.
Explanation:
A convert communicator is someone who speaks against something they used to do, advising people to no follows the same path. This type of communicator is seen as a credible source, since they speak from a place of experience. In the given situation, the guest speaker is a former drug dealer and user who has suffered the harsh consequences of his behavior. He is most likely taken very seriously by his audience.
