The early trading companies did differ strikingly from modern multinationals in many respects. They depended heavily on the national governments of their home countries and thus characteristically acted abroad to promote national interests. [ 3 differences are listed like" they... they... they... " and "they" refers to "The early trading companies" So it's clear that the passage only explained one side characteristic.

provide competitors with a better opportunity to undercut the airline's fare. [weaken] no profit for competitors => B
key word: competitor should appear in the right answer!

再次证明resulting from不可以前面加个逗号单独做状语。

这道题的黑体部分划错了。第一个黑体应该在第一个逗号前截止。

Between 1-2. 眼瞎了吧我，看成了大于2.

排除法
C(3，10)-C(3，6)=100

Alice去年的收入每月一样，她每月都会存下同样多的钱
年末，她存下的钱，是她每月收入中没存的钱的三倍
她去年省下的所有钱都是来自她的收入，她每月省下了收入的分数？
设月薪y，所求为 X，12*y*X=3*（y—y*X），X=1/5

一捆牌，每张牌后面都有一个正整数写在上面，在一个乘积游戏里面，一个娃拿张牌，然后乘以比这张派数字打一个数的整数，如果每一个可能的值是在15-200之间，牌最大是多少，最小是多少？

这题解题思路：相邻两数相乘要大于等于15并且小于等于200
那就是：X(X+1)>15 X(X+1)

", or N. " 可以有"或者说"的意思吧。我觉得E是不是in English的位置错了，如果in English在逗号前面是不是就对了。 关于“, or N."的“或者说”意思，请参考， OG2018V-SC-289. 两个是不是一样？

出现两个时间段的一定要看清楚！

B: The principal error here is the misplaced modifier: 'to best extract their flavor' mistakenly refers to saffron threads, leading to the absurd conclusion that they are extracting their own flavor.
C: You are right to be suspicious of the word 'being.' The principal error here, though, is lack of parallelism: since the first half is 'soaking them in liquid', the second half should be 'pounding them with...'.

if you say "when + PAST PARTICIPLE", then this automatically applies to the SUBJECT of the clause to which it's attached.
this strikes choice (d), since the SUBJECT is "recently documented examples", not "mice" as required.

B:in this version, "exceeding virtually every other immigrant group" is written as a modifier that is modifying "rates of entrepreneurship". therefore, you have a comparison between rates on the one hand and immigrant groups on the other hand -- a nonsense comparison.

"those" stands for "rates of entrepreneurship", not just "rates".

"Mideast immigrants" is wrong; "immigrants from the Mideast" is better. ("Mideast" can't be used as an adjective of nationality, for the same reason you can't say "Asia people" in place of "people from Asia".)

it doesn't make sense to use 'each' AFTER the comma, because it's not true that each structure was connected with a road system. instead, the road system connected all of the structures with each other, which is nowhere close to the same thing.

E: the "usage"...is in small quantities--WRONG
C:"taking...is done in large quantities"--WRONG

做完很多prep 08的题并详细研究prep08的语法笔记，发现prep08语法题与现在的语法题有很大出入了。比如说which的就近指代，后置定语的就近指代，在prep08中都是可以跳跃修饰的。这在og16和17中前所未有，OG中140道题我每道题都做了笔记，每个选项都做了细致分析，没有发现一道有跨越修饰的题。且句子工整，非常完美，一点毛病挑不出来。所以说，还是要以OG为主，OG才是最具有发言权的东西。一定要重视OG！做题数量不等于质量！prep与现在的年代久远，很多考点与现在的语法题都有出入（我个人见解），只能作为参考。比如这道题中的比较省略现象，在og16和17所有比较题型中都没有出现过。说明OG已经不推荐这种用法了。朋友们要自行评估，自行思考！

one could say that d isn't 100% parallel, but it's definitely more parallel than the other choices: in cooking, (noun) is used (passive voice construction); in medicinal usage, (noun) are taken (passive voice construction).

请问D为什么错了？ D说人们喜欢听某种音乐和该音乐的演奏质量无关，那即便演奏者无talent人们还是会喜欢啊，这样不就是学习古典乐的音乐家少了=有才华的音乐家去学习古典乐少了=古典乐表演的质量下降了=没有人能欣赏到古典乐的美了 推不出：人们抛弃古典乐转而喜欢别的流派的音乐了
