求助GWD12的几道语法题，谢谢

Q1:
A mixture of poems and short fiction, Jean Toomer’s Cane has been called one of the three best novels ever written by Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man.
 
A. Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man
B. Black Americans—including Native Son by Richard Wright and Invisible Man by Ralph Ellison先行词为novels
C. a Black American—including Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man
D. a Black American—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man
E. a Black American—the others being Richard Wright’s Native Son and Ralph Ellison’s Invisible Man

这道题原来答案是B，据说很有争议，现在看到一个新的答案选E，我选的是C，关键是搞清楚其中的原因，请高人指点一下

Q18:
Unlike most other mergers in the utility industry, which have been driven by the need to save money and extend companies’ service areas, the merger of the nation’s leading gas and electric company is intended to create a huge marketing network for the utilities in question with states opening their utility markets to competition.

A. and  electric company is intended to create a huge marketing network for the utilities in question with states opening
B. and electric companies are intended to create a huge network for marketing the utilities in question as states open
C. and electric companies are intended to create a huge network that will be marketing the utilities in question, with states opening
D. company and electric company are intending to create a huge marketing network for the utilities in question, with states opening
E. company and leading electric company is intended to create a huge network for marketing the utilities in question as states open

答案选E，我选的是A，其实对原文意思不是很理解，in question as在这里是作为一个短语出现吗？或者in question是修饰前面的utility？

谢谢！

Q1:

A mixture of poems and short fiction, Jean Toomer’s Cane has been called one of the three best novels ever written by Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man.

A. Black Americans—the others being （一般不用being）Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man

B. Black Americans—including Native Son by Richard Wright and Invisible Man by Ralph Ellison

C. a Black American—including Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man

D. a Black American—the others being （一般不用being）Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man

E. a Black American—the others being （一般不用being）Richard Wright’s Native Son and Ralph Ellison’s Invisible Man

整体句意看，JT的书，属于最好的书中的一个。

A，一般不用being，后面的句子解释作者，而不是解释作品。主句中的主语是作品。

C，a Black American，一个作者，后面不能including其他作者。

D，同C，不用being

E，相比B，我会选B。（GMAT语法，要求选最优答案）

Q18

首先：好奇怪的思路……

其次：

中文意思：当美国使他们的设备市场走向竞争的时候，与那些绝大多数为了挣钱并且扩大公司服务领域的购并不同，那些美国领先的汽油公司与供电公司则正在讨论旨在创建更大的设备销售网络的合并。

in question：正在讨论中

解释：E选项没有任何歧异。ABC选项会让人理解成一个公司同时经营汽油与电力（或者译文意思）；D选项会让人理解成领先的汽油公司与一个一般的电力公司（或者译文意思）。
