Editorial: Our city's public transportation agency is facing a budget shortfall. The fastest growing part of the budget has been employee retirement benefits, which are exceptionally generous. Unless the budget shortfall is resolved, transportation service will be cut, and many transportation employees will lose their jobs. Thus, it would be in the employees’ best interest for their union to accept cuts in retirement benefits.

Which of the following is an assumption the editorial's argument requires?

In contrast to some fish eggs requiring months to incubate, the Rio Grande silvery minnow produces eggs that hatch in about 24 hours, yielding larvae that can swim in just three to four days.
我想请问一下金栩竹老师，这道题我错选了c。在bc中纠结，选择了c。我的思考过程是，主句主语是minnow，所以为了形成对比in contrast to后面应该跟fish，留bc。但是b中，whose一般形容人的，c中“that...”可以看作修饰所以也是some fish和minnow形成比较，选择c。请金老师解答一下 谢谢！

郭老师好，这个题A和B怎么选择呢？adoption of innovations that increase its ecoefficiency定位文章的adopting ecoefficiency innovations could actually worsen environmental stresses in the future。这句话之后一直到Senge and C argue，我觉得都是细节，是需要读这些细节来选择么？

In an attempt to guarantee the security of its innovative water purification method, the company required each employee to sign a confidentiality agreement prohibiting that its water purification methods be disclosed to companies using an analogous purification process.
麻烦英吉老师帮忙解答： 我读出了要禁止的是方法被泄露这一件事情，那为什么是C比A好呢？A是完整的句子，C是短语，可是根据句子和短语的全面性片面性这个原则，不是应该选A用一个句子表达意思更完整吗？麻烦老师指出我思路的错误，谢谢！

A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.
请金老师回答一下。这个题我觉得主要的句意应该是star will compress itself into……A里面after it passes，主语没变，it重复。C里面after passing后面跟mass不对。E也是主语和状语不匹配。剩下BD就是看句意了。还是说B有语法错误我没看出来？我选了B

我有几个关于从句的问题想请金老师回答一下。如图：第一题是就近修饰还是可以修饰前面两个并列成分？如果可以修饰并列成分那么如果crest和trough是单数的话后面的动词也得用复数形式。第二个就是这里的D用的是从句，上课讲了一个题里说是从句表达意思更清楚。这里为什么不选D？
