Scientists have dated sharp-edged flakes of stone found in the fine-grained sediments of a dry riverbed in the Afar region of Ethiopia to between 2.52 and 2.60 million years ago, pushing back by more than 150,000 years the earliest date when it is known that humans made stone tools.

A. when it is known that humans made

B. at which it is known that humans had made

C. at which humans are known to have made

D. that humans are known to be making

E. of humans who were known to make





OA IS A
RON:
"the date when" is used for actual, precise calendar dates
,"the date at which" is used for the usually more vague dates of historical events


in choice (a) is that the clause following "when" is "it is known". in other words, that choice suggests that the fact is (was?)known at that date,
in the correct answer, the "at which" is followed by a clause whose subject is "humans", and which describes the actual action that took place at that date.
idiomatic usage of the construction "known to".
if the action is in the present, "known to VERB";
if the action is in the past, then you use "known to have VERBed".

感谢楼主总结！但是这里并不是but做介词，but做介词是除了的意思。上题的解释是，are not... but are 这个idiom中are是可以省略的，除非but有做介词理解（以至于引起歧义的可能），比如题目里面are not 这句话后面又有修饰语because xxx，but 在这里可以理解成修饰because 里面的，有造成歧义的可能，因此在这里are不能省略。
在这两题中，but都作为转折连词。第二题的C的it指的好像是achievement，而这个achievement指的是culminated 那一整句话，而不是conquest，否则which从句是可以的，因为前面提到了culminated in
early 17th，而achievement又是 in the same century，所以我觉得achievement应该指代一整句话做同位语。而C中it的错误是，这是一个定语从句，kings attempted to repeat the achievement，but kings were not successful （to repeat the achievement），achievement已经在前面了，所以不应该有it，并且successful at the achievement 总觉得这个表述好像不太对……
我理解里面可能but的平行没有那么严格，and的平行更严格一些……

另外我搜到这个帖子其实是不明白as in the case of 这个用法，不知道楼主可以讲讲吗？在那个pharmacy的题目里，Ron说把with 改成 in是可以的，但是他没有详细讲，但是在太阳燃烧氢气的那道题里，里面的as in the case of any stars of similar mass, once the hydrogen in the Sun's core is exhauseted... 这个选项又是错误的，Ron也没有提到这里的as in the case of，虽然那个选项还有其他错误，但是我想知道，as in the case of可以像as be the case with 一样用吗？需要主语对应吗？

The parachutelike membranes 这道题答案应该是D，解释也是D的解释，应该是顺序或者哪里错了吧……

未解
