It is sometimes assumed that personal interviewing is the most accurate of all survey research techniques. Although personal interviewing may be accurate in many cases, human errors may prevent a researcher from obtaining valid results. Questions perceived by the interviewee as an invasion of privacy or threatening in any way will probably produce false or partially true answers. Also, since the interviewer must interpret the respondent's statements, a certain amount of information lose 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 or 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.
It can be concluded from the passage that when all the people to be interviewed are located in a relatively big geographical area______.
A．personal interviewing is most effective
B．personal interviewing is economically impractical
C．personal interviewing is the only technique to get information
D．telephone interviewing may not be used

But the article is actually quite optimistic, as it outlines a potential solution to this problem, suggesting that an approach(which involves a one-hour, next-to-no-cost program) can close 63 percent of the achievement gap(measured by such factors as grades)between first-generation and other students.
The authors of the paper are from different universities, and their findins are based on a study involving 147 students(who completed the project)at an unnamed private unive rsity．First generation was defined as not having a parent with a four-year college degree Most of the first-generation students(1 percent) were recipients of Pell Grants，a federal g rant for undergraduates with financial need，while this was true only for 8.6 percent of the students wit at least one parent with a four-year degree Their thesis-that a relatively modest inte rvention could have a big impact-was based on the view that first-gene ration students may be most lacking not in potential but in practical knowledge about how to deal with the issues that face most college students They cite past resea rch by several authors to show that this is the gap that must be na rrowed to close the achievement gap.
Many first-gene ration students"struggle to navigate the middle-class culture of higher education，learn the&39;rules of the game，&39;and take advantage of college resou rces," they write And this becomes more of a problem when collages don&39;t talk about the class advantage and disadvantages of different groups of students Because US colleges and universities seldom acknowledge how social class can affect students&39; educational expe rience，many first-gene ration students lack sight about why they a re struggling and do not unde rstand how students&39; like them can improve .
