我觉得这几个选项都没啥问题啊。 1、是因为density只能用大小来描述吗？所以带有more than的都错误？ 2、A选项中more numerous than有啥错误吗？ 3、不太能理解should的意思

Regulators are likely to end what are, in effect, long-standing exemptions permitting pilots of small turboprop aircraft at small carriers to fly as much as 20 percent more hours per month than pilots at larger airlines fly, with the consequence that some carriers could be forced to hire additional pilots.
想请老师比较一下C和E选项（错选C）因为感觉E的do如果要对应是不是应该是to fly或者to do呢？以及and consequently这个and不会多余吗？它是不是要与前面构成并列呢？

Researchers hope to find clues about the A'mk peoples who lived in the Kaumpta region about one thousand years ago but who left few obvious traces. The researchers plan to hire the few remaining shamans of the modern-day indigenous people in Kaumpta, who are believed to be descended from the A'mk, to lead them to ancestral sites that may be the remains of A'mk buildings or ceremonial spaces. The shamans were taught the location of such sites as part of their traditional training as youths, and their knowledge of traditional Kaumpta customs may help determine the nature of any sites the researchers find.

Which of the following is an assumption on which the success of the plan depends?

Because it regarded the environmentalists as members of an out-of-state organization, the city council voted that they are denied permission for participating in the parade.
请问唐瑭老师，AD两个选项被排除除了时态的问题，里面they的指代是不是也算不清的（因为一开始没看到时态觉得是指代的问题）？B不对是因为that后面跟的句子里没有谓语动词对吗？C说不上来是哪里不对，跟them的指代有关？但E又是对的，所以不存在them指代的问题吗？另外为啥不用their用them，感觉应该有个所有格的形式…

A March 2000 Census Bureau survey showed that Mexico accounted for more than a quarter of all foreign-born residents of the United States, the largest share for any country to contribute since 1890, when about 30 percent of the country's foreign-born population was from Germany.
请问老师划线部分作为一个同位语插入，the largest share不会让人以为是就是Mexico或者US的吗？这道题E选项不好的点在哪里呢？是因为不简洁吗？马上就考试了，很着急，谢谢！
