C:when状语从句的主语应该是the use of bar code

C的真正错误在于which在这里不适合，一定要用that引导这个从句

对选项E的补全：drivers will be as likely to exceed the proposed speed limit as they are ( likely to exceed) the current one

D选项的also是副词，可加可不加

纠结在C，有人能解释一下C错在哪儿了么？

it不是可以指代从句么，那B中的it为啥不能指代前面整个since带的原因状语从句呢？

that cannot refer to opponent (ppl), only who could refer to opponent, thus in this place, that refers to statements

补充一下，认为是环境管理问题，因为这个问题是environmental manager faced。emmm 除非说这不是个问题？

D选项的解释不通吧，为什么必须是目的关系？当做平行讲也完全说的通啊。他们工作三件事：1.strengthen market，2.cooperate with government，3.improve farmers accessibility to productive resource。倒是把for farmers拿掉之后，access for sth 这个说法比较awkward吧。

那我想问一下啊，如果不是环境管理问题，那由于环境管理而导致的不均衡是个啥问题呢？

C选项里为什么Earth would grow 可以省略呢？

老师 我有个疑问 之前说到独立主格的从句主语不等于主句主语， 这里的 NOW with numbers five times greater than 他修饰前面的那句话的survive， 所以主句的主语是THE gyrfalcon， 从句主语是 numbers give times。 请问我的理解正确吗

c选项small moths are more likely than large moths to be effectively camouflaged while on vegetation和前一句话In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures,。。。无法match，重复了，前一句话说的是更容易逃脱，而c选项说的意思是大蛾子不容易有效隐藏即不容易逃脱。。b和c对比应该是b更符合语境
语境！！！

e为什么不对

"More than all the North American Great Lakes combined" modifies "20 percent of the world's fresh water."
