我记得好像有with引导做原因的情况，那b选项中 With a law passed .... 为啥不能做原因状语

AB选项hold主谓不一致。但是有的题解析不是说because of后面不能接复杂的成分吗。。。所以纠结了好久把D排掉了。。

倒装形式的独立主格结构，实际上是the threat of a rival’s multibillion-dollar patent-infringement suit and the decline in sales of the company’s powerful microprocessor chip among them,倒装可以避免头重脚轻，更重要的是among them中的them离其指代对象challenges更近。

发现so that的结构还是错选C，神他么的so+独立主格，太坑了

选项D：event并非拥有number，被动语态的表达很牵强。

按OG的讲解，原文altered work tasks, skills, training opportunities, administration, and organization of workers可以被归纳为C选项中的impact of changes in the technology of switching at the exchange in terms of overall operations and organization。
问题是一不完全理解C选项的翻译，in terms of是修饰什么的？
二是不明白OG提供的逻辑——题目提到的是information，为什么直接定位到empirical level了？

正确选项C有点没读懂，可以翻译一下吗？
in terms of overall operations and organization是修饰谁的？impact还是exchange？

units digit= 个位数

B选项
initiatives 后接that引导的定语从句，initiative不能发出try的动作，所以定语从句应该改成to do不定式表示目的；同时 try的时态也应该是过去时，同announced同一

考的是usher这个词的用法
The basic idiom is:
I usher X in.
If I want to specify the region in which this X is introduced, I would say:
I usher X into A.

原文：最低工资将被提高至5.50 但是对经济没有什么影响，因为现在很少有工人的工资是低于5.5的
削弱：很多trainee的工资是在最低工资附近的，但是trained workers的工资是要高于trainee的，所以一旦trainee的工资涨了，那trained worker的工资肯定也要涨，所以很多工人的工资都要涨。

这里是有两个党派，看成了同一个。。。
the Virginia Whig party 辉格党最先1840
Virginia Democrats民主党在1950模仿：Virginia Democrats, in response, began to make similar appeals to women as well

定位第二段第一句

假设平均工资是m，a个manager, b个director
所以可以得到m(a+b)=(m-5000)a+(m+15000)b
=> m(a+b)=ma-5000a+mb+15000b (ma和mb项提公因数m)
=>m(a+b)=m(a+b)-5000a+15000b (两边减去m(a+b))
=> 5000a=15000b
=> a=3b
可以得a/(a+b)了就

k < m < r < s < t

不能直接

可是题目中说了是slow-moving river water啊 就可以排除选项中的dry up completely了吧

用火狐浏览器没问题

In order to act as an action modifier, the having modifier must be preceded by a comma. But there is none in the original sentence.

Choice A does not stand as a correct answer because the intention of the sentence is to show the sequencing of the events. But the having modifier now just presents the additional information about men and women. It is not really associated with the action opened up as such.
