A is to B what C is to D

and连接两个无关的句子，排除CDE
B. them 和 themselves 指代混乱

B. 应该是creates
C. along with 意思错误
D. 应该是create
E. 应该是creates

e：这里说是形成转折 不如说是更加平行
错选d
d与e相比 转折不强烈 e较优
e中的public提前 与前文的magazine 对应

是an expanding cloud of energized particles点亮了北极光，使卫星失效，且后两者并列结构

BDE.which/although 引导从句 restricted their gains，前面limiting主句成分残缺

根据句子结构和语义排除BCD。错选E：more than should modifier "fresh water",该句中紧跟修饰Siberia's Lake Baikal，排除。
【RON】when you have an INITIAL MODIFIER THAT'S NOT A CLAUSE (i.e., it doesn't have its own subject and verb), then it must modify the immediately following noun.
same problem in choice (e), which implies that lake baikal itself is somehow "more than all the North American Great Lakes combined".
that doesn't make sense.
关于A的两个modfiers："more than all the North American Great Lakes combined" is actually a MODIFIER of "20% of the world's fresh water", which is WITHIN the first MODIFIER. therefore, it's a SUB-modifier, so to speak.
let me try to illustrate it graphically:

More than 300 rivers drain into Siberia's Lake Baikal(, which holds 20 percent of the world's fresh water(, more than all the North American Great Lakes combined)).

the blue modifier modifies stuff that's inside the orange modifier, so it falls within the orbit of the orange modifier; it MUST be removed if the orange modifier is removed (because it has nothing left to modify).

A.remainder of drug spending错误，应该是remainder of the increase

second only to仅次于

D. which定语从句不能修饰that

B.so...that
C.be able to主语一般是有意识的行为主体，故不用被动
D.not位置错误
E.enough to do

he sentence is stating a contrast: condition X is true for cod and haddock, but false for monkfish.
here's another example, similarly constructed:
[i]There is no snow in Los Angeles, as there is in more northern locations.
there be句型的平行要补出there be。
b比较 there be限制比较 鱼

unequaled ——无与伦比，不可比较的

Alternative explanation是寻求替代解释，即削弱。
Result：买套票的人出席更少。
问：除了成本以外的原因是什么。
A 是成本cost相关的原因，不能成为alternative explanation
BE无关选项
排除C 出席所有play的人可以得到refund（成本相关不能成为alternative explanation），同时是增强选项。
至于为什么D正确我也不知道

两个句子态度相同，排除BC
argument：今年的new jobs会比去年的少
第一句：现存的公司中 今年的比去年的少
第二句：因为新公司比去年少，所以新工作肯定比去年少
第一句、第二句都没有challenge论点，排除AE

第一句假设：因为缺少prey所以range widely
第二句：do range over larger areas&sort food is sparse.
两者态度相同排除C、D
排除A、E：第二句shown that是表述一个现象，排除states conclusion

exclusively 仅仅 而不是除了
A重复文章第一句话，这句话是general的结论。但这道题不是要求总结general的观点，而是要求解释why exercising the power to spend public resources involves the ultimate exercise of state authority
B翻译：只有直接代表citizen的government能够行使这项权力

convinced确信，后面肯定不会还跟虚拟了呀，直接用will

C错在哪里呀？做题时还考虑了一下between 1990 and 2000应该做定语修饰economy的呀，A的话就是状语了吧

第二次错！句子中没有出现be
