在确认答案前，请确认是否每个选项考虑充分！2的9距离一定在圆外！

If zy < xy < 0 ，
1结合if，则自然y>0
2结合if，则自然z

没有考虑1 @ 0 ，只要不为零，12都可以

忽略隐藏条件, 知道平均数，另外两个数也可以得出！

为什么OG解释说，D用hurt和raise在一起逻辑上不对？一般现在时也符合now的情况啊--求解释

other forms of advertising. 是有可比性的，不算无关选项。C选项才是无关选项，因为没有说targeted 的广告和仅仅看一眼还是看两眼有关系 不要瞎脑补

A 的they 指代buds，其他都有硬伤；
B-from where 错；
C-Protect应该单数；
D-since+consequently 赘余用法；
E-Because+as a result 赘余用法；

同时性？

D迷惑了，求老师指点。

ron：
the sentence is supposed to say that today's small cars are more fuel-efficient than previous small cars -- i.e., OTHER small cars.
this is important, because you can't use a "they"/"their" construction (which would illogically imply that you're talking about the same small cars mentioned in the first part of the sentence).
the use of "those" in (c), on the other hand, accomplishes this distinction nicely.

less不是用于不可数吗 这里costs可数啊

名词和从句的区别？

A: it's in the non-underlined part, about 1/2 line from the beginning of the sentence. the first word of the underlined part - the split between "because" and "in..." - is attached to "differ", although there's an intervening prepositional phrase (the one beginning with 'from').

 教训是读statement要每一个都读清楚

这个题目是不是有误？第一个黑体明显和第二个黑体的关系是对立的，不是支持的，C说不通啊？

感觉是相关因果

A&B: "based on" -> wrong meaning
C: "according to" is fine as an opener. but not parallel with "...that this robe" in the last half of the sentence.
D is right. indicate that x... and that y. X and Y are ideas that are parallel to each other.
E: indicate "that". "that" is missing.

eventually be significantly higher 这个eventually的意思不就是最终么，所以就算是在校时间长了，学生也还是会毕业，最终进入job market 啊。。。

D项 - 如果这些动物是未知物种，那么对它们的生活地点的判断就可能是错误的，所以可能是确实在S需生存过的.... 这样的理解问题出在哪里呢？
