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.)

B. atmosphere, with interactions affecting.

答案是a, 一个同位结构。我想问一下b独立主格用在这里为什么不合适。是因为如果用了b就表示with后面的是修饰atmophere了么？ 独立主格有什么类似的修饰规则么？

请nn解答，谢谢了：）

interactions between the ocean and the atmosphere, interactions that affect global climate. 第二个interactions做同位语,补充解释了前面的那个interactions.而如果用with interactions...的话,可能修饰句子的主语an array of buoys,逻辑上不对,就算是修饰,前面的名词atmosphere,逻辑上也不对.

同位语的用法在OG和大全中很经常出现的.

请指正.
