GWD-9-02，居然没有人问

GWD-9-Q2:

In an attempt to produce premium oysters, a firm in Scotland has developed a prototype of a submersible oyster farm, sitting below the surface of the ocean, and it provides ideal conditions for the mollusks’ growth.

1. farm, sitting below the surface of the ocean, and it provides

2. farm, sitting below the surface of the ocean for providing

3. farm that sits below the surface of the ocean and providing

4. farm that sits below the surface of the ocean and provides

5. farm that is sitting below the surface of the ocean and it provides

可能问题太白痴了，居然没有人问。

这题我选了B，因为我觉得providing是分词形式，前面整句话才是它的主语，而并非是并列关系。

我感觉原句用了it就是要表达这个意思，只是it不能指代整个句子。

当然，B用for providing 也不好。

请大家帮我看看。多谢！！

我做的时候看到for providing就排除了B，我选D

如果不管for providing的问题，我觉得B只从修饰上说没什么问题，

不过逻辑意思说不通。不管是前面的句子还是句子的主语作逻辑主语，后面的非谓语应该能够表示出目的或结果

这题从意思上来说B就不对了，sitting below the surface of the ocean 显然应该是修饰farm

逻辑意思很重要的

This is my opinion
