dated 不能用不定式（因为描述的是一个客观的东西）
date to/at

只要用its return，都会产生“彗星和彗星的轨迹”进行对比的歧义

第五题：选项C里面的which有两点需要判断：1：主谓一致，2：which修饰名字有就近原则。 主谓一致优先于which就近修饰原则吗？

既然解析里面E已经说了会有效果，那不就说明方案可行吗？那为什么不选E？

B is wrong, please correct! B. Marlandia separated from a much larger landmass about eighty million years ago.
for E: This shows that reptiles would have to survive at land as it cant survive in sea for sure.

代词代词代词！如果是them就指代的是trees了，而不是moose。然后根据语义从A和E中选出答案。

a选项是这个星星被announced，应该是discovery被announced。另一个排除a的点是，to be sighted是修饰的star，按照句子结构分析，was。。。by。。。缺少了observed，正确应该是was observed by...

对比题 linguistic census in France vs linguistic census in Britain

就是个distinguish from。。。

A/B the mass of what?
C：GMAT老毛病不喜欢if的问题；it这里指代mass而不是star;以及最好用the mass of star
E: it指代问题桶C; passing的修饰对象是mass错误

注意后面是sisters...

A/B的错误在于by放在这里语义不清，而CDE中出现的conducted很好的描述了这个组织所起的作用
C：underwritten容易被理解为就近修饰programs不对，这里应该是修饰study，
D：很好的修正了C的问题
E：it is underwritten by这里it也指代不清，而且不如D表达清晰

比较的两种动作，不是动作和人~

If the higher FD fees make up a substantial portion of the company's revenues, then it is very possible that the proposed change would reduce revenues significantly enough to lower profits.

SO MUCH AS
NOT BUT放在这里so much实在是不完整

inherent的应该是difficulty of the goal而不是contradictions in the goal，文章只是说投票权运动in general都失败了，女性投票权运动当然也会失败，这并不是一个contradiction.

这段话并不是作者观点，只是作者在转述学者的观点，作者对于1920s的女性运动发展还是报一定的正面态度的，误选了C

If we suggest that beets and carrots are usually consumed with high-protein foods that counteract these unwanted effects, we have good reason not to be concerned about their consumption, at least in regard to their sugar level and glycemic index.
C. The nutritionists advise people to avoid foods high in sugar and high on the glycemic index despite any nutritional benefits they may confer.

官方解释说hopefully表示let's hope...不正式，要避免。。。
