选项解析：
The subject of the sentence is "one of the most problematicethnic groups", a singular noun. The verb, however, is "were,"which is plural. We need to find a choice that uses a singular verb instead.
(A) This choice is the same as the original sentence.
(B) This choice does not correct the subject-verb issue; it stilluses "were" to refer to "group."
(C) This choice uses the singular "was," but the simplepast is not the appropriate tense here because of the ongoing nature of theproblem. Moreover, "the reunified Germany's most problematic ethnicgroups" is an awkward construction.
(D) CORRECT.This choice uses the singular"has been," which is also in the present perfect tense, indicatingthe ongoing nature of the problem. Moreover, "in terms of cultural and economicassimilation" is a more idiomatic and elegant phrasing than that of theoriginal.
(E) This choice does not correct the subject-verb issue; it uses"have been" to refer to "group."

题目点评：
涉及考点：主谓一致、时态、句子结构（简洁）

所谓秒杀，其实是指用最最熟悉的概念来排除错误选项，正如下面网址中的文章Too Many Decisions CanDrive You Crazy中所论述：
Ditto with sentence correction – allthe companies tell people “look for differences” (we call them “splits” atMGMAT) and, to save time, deal with the splits that can help you eliminatemultiple answers (we call those 2/3 splits at MGMAT). For me, though, it’s tooexhausting to try to figure out what the “best” split is. I find a difference.The only thing I care about is: do I know how to deal with this difference? Ifyes, I deal with it. If no, I go find some other split that I canhandle. Asking myself which split is the best one to do first – no,that’s not a decision I really need to make during the test.

根据最熟悉的主谓一致先排除A,B,E（某个选项出现的某个最明显错误，往往在其他选项也存在，那么看到那个错误以后，先停下来不继续看完该选项，而是找其他也有这个错误的选项）；或者因为since和after的重复，排除A,B（哪个让你反应更快就用哪个）。

比较C，D：one of the reunified Germany's most problematic ethnic groups显然太啰嗦，两个所有格（注意不是双重所有格），表述起来显然没有用其他介词in来替换更简洁：one of the most problematic ethnic groups in the reunified Germany，因此排除C。或者如果对时态比较熟悉，根据未划线部分的Since 1989和who have had看出用完成时更好，因此选D。

另外：in terms of 就……而言，从……方面/角度来说（常见用法）

思维点评：
1，“如果since和after要表达的是不一样的意思，放一起也没有错误的把？”——若雪
Since 和 after本来要表达的意思就不一样
Since 表达的是一个时间段的概念；after表达的是一个时间点的概念。两者之所以不能同时用，并不是意思相同的原因，而是两者的作用是相同的，都是用于引导时间状语从句。

2，“1) one ofthe reunified Germany's most problematic ethnic groups
2) one of the most problematic ethnic groups inthe reunified Germany
疑问：两个句子的意思是否一样？”——ViannaLIN
虽然直译成中文感觉意思不一样，但实际上要表达的内容是一样的。

做题小tips：
实战时，一定不要思考太多，选项是比较出来的，但是比较的时候并不是要比最明显的点，而是比你最熟悉的点。这样不仅仅能提高速度，更加能节约你的脑细胞。要知道，顶尖运动员都是最懂得节约能量的人。

9. Since 1989, after the Berlin Wall hadbeen demolished, one of the most problematic ethnic groups in the reunifiedGermany, in cultural and economic assimilation terms, were the former EastGermans, who have had to acclimate to an entirely different politicalsystem.
       A       after the Berlin Wall had beendemolished, one of the most problematic ethnic groups in the reunified German,in cultural and economic assimilation terms, were the former East Germans
Since1989,after..had done的结构中，根据句意，after...后的从句应该修饰的是1989，但1989是一个时间点，不能用had been（由过去的过去延续到过去）；were应该改为was
       B       after the Berlin Wall was demolished, oneof the most problematic ethnic groups in the reunified Germany, in culturalterms as well as those of economic assimilation, were the former East Germans
as well as表达的是从属关系，改变了原句的并列关系；were错
       C       when the Berlin Wall was demolished, oneof the reunified Germany's most problematic ethnic groups, in terms of culturaland economic assimilation, was the former East Germans
       D      when the Berlin Wall was demolished, oneof the most problematic ethnic groups in the reunified Germany, in terms ofcultural and economic assimilation, has been the former East Germans
       E       after the Berlin Wall had beendemolished, one of the most problematic ethnic groups in the reunified Germany,in both terms of cultural and economic assimilation, have been the former EastGermans
had been 错      both terms of cultural and economic assimilation平行结构形式不对称   have been单复数错

根据主谓一致，one of the problems...后面应该跟谓语动词单数，排除A B E， the reunified Germany's most problematic 的表达不够简洁，选D
GMAT语法中，N‘s的表达容易产生歧义，一般不常见，多用N1 of N2的结构
