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 findings are based on a study involving 147 students(who completed the project)at an unnamed private university.First generation was defined as not having a parent with a four-year college degree Most of the first-generation students(59.1 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 intervention 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 narrowed to close the achievement gap. Many first-gene ration students”struggle to navigate the middle-class culture of higher education，learn the‘rules of the game，’and take advantage of college resources,” they write And this becomes more of a problem when collages don’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’ educational experience，many first-gene ration students lack sight about why they a re struggling and do not unde rstand how students’ like them can improve. Recruiting more first-generation students has______ . A.reduced their d ropoutrates B.narrowed the achievement C.missed its original pu rpose D.depressed college students The study suggests that most first-gene ration students______ .A.study at private universities B.are from single-pa rent families C.are in need of financial support D.have failed their collage The author of the paper believe that first-generation students______ .A.a re actually indifferent to the achievement gap B.can have a potential influence on other students C.may lack opportunities to apply for research projects D.are inexperienced in handling their issues at college We may infer from the last paragraph that______ .A.universities often rect the culture of the middle-class B.students are usually to blame for their lack of resources C.social class g realy helps en rich educational experiences D.colleges are partly responsible for the problem in question The author of the research article are optimistic because______ .A.the problem is solvable B.their approach is costless C.the recruiting rate has increased D.their finding appeal to students 请帮忙给出每个问题的正确答案和分析，谢谢！
