The ivory-billed woodpecker, once the largest woodpecker in North America at a striking 20 inches tall, has moved in and out of the extinct category, with scientists consistently unable to find solid proof for the bird to still exist.
for the bird to still exist
for the bird as still existing
for the bird's continued existence
that the bird still exists
of the bird and its continued existence
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
find solid proof for the bird's continued existence，为existence找证据
find solid proof that the bird still exists，找到鸟仍然存在的证据
The only real error in choice C is "proof for...", as you noticed. It's not decidedly more wordy than the correct version.
for做介词为了，做连词因为
宾语后边的介词短语可以做状语，定语或者宾补。这里ABC无论做啥意思都不对，E鸟的证据 不对，D表示证据的内容是鸟还存在，符合逻辑，正确
名词和从句的区别：
名词表示有时间终点，一般指事情已经结束。从句表示看不到终点。
这里鸟存在与否还待确认，而不是已经确认的事情，所以是没有时间终点的。
proof of sth比proof that好，that引导同位语解释说明proof的内容是鸟仍然存在
C，find proof for bird's existence，for作介词，接名词表示为某人做某事，do sth for sb/sth，解释不通；接doing表示用途或原因，The knife is used for cutting things. Thank you for coming to see me. 两个意思都不适用于proof和existence的关系。
proof of / proof that 都可以， 朗文 proof of purchase/ ownership/ identity ，我的理解1，动词优于名词 2，that 从句指明这是一件事，并非一个名词

介词表特征且介词自己是有含义的（for：为了），同位语才是对先行词具有解释力
C - 定语， 说的是proof的特征； D - 同位语从句，说的是proof的内容。选D，因为是内容。
proof of ... 或者 proof that ... 但proof for ... 是错误的搭配。
此题求讲解。D选项正确，是同位语。C选项为什么不能看做是proof的定语？
同问。C选项作为定语，难道是应该把the bird's continued existence改成the bird's continuing existence?
