In this part there are four passages. Each passage is followed by a number of comprehension questions. Read the passage and answer the questions. Then, mark your answer by blackening the corresponding letter on the Answer Sheet. Personal interviewing is most effective when all the people to be interviewed are located in a relatively small geographical area. Otherwise, the time and expense spent in travelling from one person to another makes this type of interviewing economically impractical. Personal inter viewing is usually used when the information needed is too complex to be gathered by another technique. For example, a problem being studied may require the interviewer to probe beyond the more superficial answers that might be obtained with another method. It is sometimes assumed that personal interviewing is the most accurate of all survey re search techniques. Although personal interviewing may be accurate in many cases, human errors may prevent a researcher from obtaining valid results. Questions perceived by the interview wee as an invasion of privacy or threatening in any way will probably produce false of partially true answers. Also, since the interviewer must interpret the respondent’s statements, a certain amount of information loss results even though the respondent may be answering truthfully. In spite of the problems, at least two major advantages are provided by this research technique. First, the alert interviewer can generally tell if the respondent is being truthful of if he or she is giving superficial or untrue responses. Second, the interviewer can rephrase questions, give more explanation, or probe more deeply if the initial questions do not produce the information desired. As a result, the information gleaned should be more accurate than that provided by interviews where no one is present to clarify questions or to interpret answers.
