GWD6-Q13:
Floating in the waters of the equatorial Pacific, an array of buoys collects and transmits data on long-term interactions between the ocean and the atmosphere, interactions that affect global climate.
A.    atmosphere, interactions that affect
B.    atmosphere, with interactions affecting
C.    atmosphere that affects
D.    atmosphere that is affecting
E.    atmosphere as affects

答案是A.  我选的是B.  另外 我记得XDF里说 AN ARRARY OF + 复数N , 谓语动词用复数. 难道是我记错了?

an array of ..., a collection of ... 都是跟单数
而且前面出现了interactions between ... , interactions that ... 在这里做前面那个interactions的重复性结构的同位语。
B中加了个with，破坏了这种结构。
