Delta 中的一道阅读题

PASSAGE：

... Her well-rounded artistic talents empowered her to work historical references into buildings constructed with modern methods and materials. She preferred to use materials indigenous to the region, such as Kaibab limestone and yellow pine.     She took great stock in materials and setting, gathering many of her materials on-site and incorporating them in their natural state into her projects. She treated building and site as integral halves of a single composition and merged them seamlessly...

题目： The word them in the paragraph refers to

        A.  modern methods and materials

        B. her projects

       C. building and site

        D. texture, pattern, and color

答案是C。 语感告诉我是materials,分析句子结构觉得是不是因为gathering & incorporating 都是从句所以THEM代表的是MATERIALS AND SETTING，转化为BUILDING AND SITE，可感觉有点牵强。

请大家帮忙看看

哪句的them

She treated building and site as integral halves of a single composition and merged them seamlessly...

我是这样想的。

原句是这两句的和并 ，

1。She treated building and site as integral halves of single composition.

2。she merged them( building and site) seamlessly.（她将建筑与地点结合的天一无缝。）也就是说她利用地势来建筑building.

所以c 对。

She took great stock in materials and setting, gathering many of her materials on-site and incorporating them in their natural state into her projects.

我想这句可变成这句。

When she gother many of her materals on-site and incorporated them(her materials) in their(her materials') natural into her projects, she took great stock in materials and setting.

不好意思

哈哈

没看到下面还有个THEM

谢谢大家

要是我出这题,我会把halves 也做为一个备选项.

I think the halves infer to  the building and site. Do you think so?

Yes: here;: halves infer to  the building and site:

"Them" refers to "building and site"

Thanks. I completely and surely understand this sentence.
