103. El Niño, the periodic abnormal warming of the sea surface off Peru, a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated in the western Pacific to flow back to the east.

(A) a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated

(B) a phenomenon where changes in the ocean and atmosphere are combining to allow the warm water that is accumulating

(C) a phenomenon in which ocean and atmosphere changes combine and which allows the warm water that is accumulated

(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated

问个跟这个题答案的问题，但是好纠结，排除法得出答案是D，这都能理解，但是in which 这里为什么要用in呢？ 没有in可以不可以呢？

那就得在前面加逗号了。

如果要加， in应该要放到什么位置？

1、必须是a phenomenon in which，因为在定语从句中是做状语。如：changes in the ocean and atmosphere combine 。。。in a phenomenon 。

2、没有in，phenomenon没法合理地放到定语从句中。

3、逗号不是gmat的核心错误点

层主，在GMAT中where 只能用来修饰physical location, 所以这里phenomenon where 是不对的哟
