1.不能用to do 是因为classify 的动作发出者不是 evidence
to是A provide,A做这件事情 for是A provide B for,B做这件事情 (C) Evidence provides support to an idea. (D) Evidence provides support for an idea. (E) Evidence provides support (to classify) something. D✔️ C: If you provide support to X, you are giving something to X: I provide support to my mom (I give something to my mom). E: Is idiomatically incorrect. By placing a verb after the preposition "to" you create a confusing sentence where it looks like "to classify" is being used as a verb. You wouldn't provide support to donate

1.不能用to do 是因为classify 的动作发出者不是 evidence
"Providing support to ___" implies that "___" is a person/organization/etc. trying to accomplish something. E.g., Volunteers provided support to the Red Cross during the Hurricane Katrina disaster relief efforts.
provide sth to sb/sth, provide sth for doing
(C) Evidence provides support to an idea. (D) Evidence provides support for an idea. (E) Evidence provides support (to classify) something. D is correct here because you want to provide support for an idea- "classifying the two elephants as different species."
provide support for sth, for 作用,to是目的
provide sth to do sth不能说是错的,如果to do的发出者和provide的动作发出者是一个人的话就可以
provide sth to X,X应该是人一类的名词,把sth给X;provide sth for doing sth是对的;provide sth to do sth错
根据对题干的理解,能够区分物种的很显然是这些证据,而不是支持本身。所以逻辑主语为A。 A provide B + to do 如果是强调B; A provide B + doing 如果是强调A. To do修饰动词,逻辑主语是to do所修饰动作的发出者 For doing修饰名词,逻辑主语是for doing所修饰的名词
to是A provide B to, A做这件事情 也就是说a do b to do c逻辑主语仍然是a to do 但是这里 不能evidence 去classify 因此用动名词 +且 for表示某种作用 to 表示某种目的 + provide sb with sth 或 for doing 固定搭配!
