Final answer:
The correct answer is E) both A and B, as both options involve the use of a computer to assist in the interview process, with A including a human using a computer and B having a computer use a synthesized voice.
Step-by-step explanation:
Among the options provided, the ones that are considered computer-assisted interviews are:
- (A) a human uses a computer
- (B) there is no human but a synthesized voice is used by the computer
Both of these methods involve the use of a computer to facilitate the interview process, either by having a human interviewer input responses into a computer system or by the computer itself conducting the interview using a synthesized voice to interact with the respondent. Therefore, the correct answer is E) both A and B.
