52. What do we learn from the passage about black students in the past 20 years?
- A. They have been unfairly treated regarding higher education.
- B. They have been battling hard to address equity issues.
- C. They have boosted their lifetime incomes by billions of dollars.
- D. They have come to see the consequences of racial discrimination.
答案：A
答案句：A 2020 report by Citi indicated that “Black students could have increased their lifetime incomes $90-$113 billon”if equity issues related to higher education had been adequately addressed over the past two decades.
参考译文：花旗银行2020年的一份报告指出，如果在过去二十年中与高等教育相关的公平问题得到充分解决，“黑人学生的终身收入本可以增加900亿至1130亿美元”。
定位线索：题干“black students in the past 20 years”→答案句取自第3段“A 2020 report by Citi”；文中“if equity issues related to higher education had been adequately addressed”对应选项A“unfairly treated regarding higher education”；文中“could have increased”（虚拟语气，表示未发生）排除选项C“have boosted”。
解析：题干问过去20年黑人学生的情况。答案句用虚拟语气“could have increased...if equity issues had been adequately addressed”说明公平问题未被充分解决，即他们在高等教育方面受到不公平对待（A）。选项C“已经增加了数十亿美元收入”偷换概念，原文是“本可以增加”（虚拟语气，未发生）；选项B“为解决公平问题而艰苦斗争”无中生有，原文未提及；选项D“看到种族歧视的后果”答非所问，原文说的是“inequity has had appalling consequences”而非黑人学生自己看到。
