答案及解析:
1.in--on
词组on the basis of 中须用介词on而不是in。
2.to(attending)--in/of
不要将objective和objective相混淆，object后需加介词to，但这里应用in或者of表示“上大学的目标是……”。
3.critically--critical
thinking在这里已变成名词，因此前面应该用形容词critical来修饰，表示“批判性思维”。
4.^attributed--been
attribute作动词时是及物动词，通常的搭配是 to attribute sth to sth，因此这里应使用被动语态，加上been。
5.economy--economics
economy表示一个国家的“经济”，而economics才表示“经济学”，因此这里应使用economics。
6.and--while/but
and表示顺接，而这里缺少的是一个表示对比的连词，因为历史系学生和经济系学生在人数上形成很大对比，所以应改and 为while或者but。
7.consisting--comprising/constituting或者 consisting^--of
consist的意思是“包括，由……组成”，一般要与介词of连用，而comprise或者constitute则表示“组成……”，而且不需要与of连用。
8.declared--declaring
“almost 12 percent of undergraduates declared themselves history majors”和“economic and business administration majors together consisting 8.7 percent of undergraduates"应是并列结构跟随介词with，所以这里应将declared变为declaring，与前面的分句保持形式上的一致。
9.marketed--marketable
原句的意思是“经济学的文凭是有市场的，有销路的”，所以应该是marketable。
10.of(high salaries)--/
garner后面不需加介词of，直接说garner sth即可。
