vote E, because the sentence meaning looks more briefly and precisely.

Prefer C

首先是因为 to determine。

虽然C把How&When分开了，有些wordy,可是在原句中也是分开的，而且是特别强调了when,所以我觉得没有什么不妥。They 的指代也很清楚是mammals。

GMAT阿驴

我也是选 E的  简洁

E吧，我记得好像在ETS里面还是比较prefer provide sth. for doing sth.的说法的。

33. From the earliest days of the tribe, kinship determined the way in which the Ojibwa society organized its labor, provided access to its resources, and defined rights and obligations involved in the distribution and consumption of those resources.

67.Congress is debating a bill requiring certain employers provide workers with unpaid leave so as to care for sick or newbom children.

174. A letter by Mark Twain, written in the same year as The Adventures of Huckleberry Finn were published, reveals that Twain provided financial assistance to one of the first Black students at Yale Law School.

48. Choice D, like A, fails to provide a noun or pronoun to perform the action of living, but even with its the phrases would be more awkward and less clear than it lives.

From OG10th, we could find 4 usage of 'provide'

1.provide sth to sth

2.provide sb with sth

3.provide sth to sb

4.provide sth to do sth

既然没有查到provide sth for doing sth的用法，那可不可能是provide sth(clues to...or clues for...),也就是clues后面的介词是紧跟clues的搭配？很可惜，google上只能查到clues to，查不到clues for的用法

so, i vote for C!

求教 到底选什么啊

以下是引用joe11在2005-12-18 14:56:00的发言：

I agree with E.

'to' is not proper here. （effective error）

Scientists claim the discovery could provide clues

    To （目的是为了，做之前有明确目的） determine

    for (为...提供线索，做之前不知道目的）determining

再读了下句子

的确是应了这个说法

本来选C,现在严重同意选E了

而且clue to虽然是固定搭配,但to是介词,应跟n或者动名词

在这里是不对的

选E!

我觉得此题应该选C。

大家中的代词指代的问题我认为不存在，这个they很清楚的表明了是mammals

不谈是for还是 to的用法，至少在gmat里，很少见到 how and when的连接，大家可以查一下。

并且在句子表示习惯上，首先说 how xxxx然后再补充说 when they did是符合表示习惯的，加不加so并不重要，我认为。。。

顾风

更何况省略结构通常是省略and后面的内容。。。

基本上没有见到过　省略前半部分的。。。
