Q17:
Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses.

A.    Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he
E.    Even though Galileo did not invent the telescope, but when he heard, 1609, of such an optical instrument being made, he

正确答案是A.

不选E仅仅是因为1609前没加in么？还有其他错误没啊？？？

我认为E选项最明显的问题是even though和but重复表达转折，因此是错误的。要么只用even though要么只用but。

1609这确实是个问题。另一个小问题是hear of sth. being done.在GMAT里一般认为是错误的结构。要么hear of sth. 要么hear that ...。

Q22:
Unlike mainstream American businesses, more than half of which fail, the failure rate for businesses in the Amish community hovers around 5 percent.
D.While the rate of mainstream American businesses failing is more than half
E.While more than half of mainstream American businesses fail
正确答案是E.
想问下D的症结在哪？说rate可以用half么？
还有the rate of后面改成failing mainstream American businesses会不会好些？？

Q23:
原句：Seldom more than 40 feet wide and 12 feet deep, but it ran 363 miles across the rugged wilderness of upstate New York, the Erie Canal connected...
正确答案：Seldom more than 40 feet wide or 12 feet deep but running 363 miles across the rugged wilderness of upstate New York...
语法点没什么问题，想问下40 feet wide和12 feet deep的关系究竟该是and还是or 呢？或者两个都可以？？

Q22：我的回答不太专业，反正就是看这个选项怎么看怎么不爽。记得一点就行了，of 后面不应该是主谓结构而应该是名词。所以我认为以下两种表达是可以接受的：1) the failure rate of mainstream American businesses 2) the rate of mainstream American businesses that fail。rate用half我没觉得有什么问题。其他同学如果有依据的话欢迎赐教。

Q23：这里的and和or在我看来是逻辑语义上的不同。and给人的感觉是同时满足条件A和条件B，or则是只满足一个条件。可能用and的时候前面要加个both吧，我不太确定。

忽然反应过来seldom是带否定意义的词，后面只能用or吧~~
个人觉得深度和宽度需要同时满足一定条件才能对河流定性，肯定情况下应该用and才对。

eg. He's not hungry or thirsty.

欢迎各位赐教~~
