the correct answer, on the other hand, explicitly states that the companies are "aware of the connotations" -- i.e., aware of the actual nature of those connotations.
analogy:
i am aware that discounts are available this weekend.
--> i know that there ARE discounts, but i don't necessarily know the specifics.
i am aware of the discounts available this weekend.
--> i actually know the specifics (percentages or whatever) of the discounts.

RON maintain that the principal issue with choice (a) is unrelated to the "with" issue. instead, the primary problem with (a) lies in its meaning.
the problem with (a) is that it says only that companies are aware "that there are connotations". in other words, literally, the companies just know that there are connotations -- in other words, that connotations (of some sort) exist -- but the companies don't necessarily know what those connotations are.

Some...... Others...... 这两个词加在一起不是全集么，于是有些没有潮汐，有些大于30feet，那么就没有0 - 30 feet的了不是么，逻辑不对啊。求指教，谢谢！

為什麼外地核是液態而內地核是固態? 不是越深溫度就越高嗎?為什麼外地核融了內地核還不融?

影響熔、沸點的因素有兩個：壓力（pressure）、溫度（temperature）
壓力愈高，熔點愈高；溫度愈高，分子運動加快．
這兩個因素在地球內部隨著深度改變而變化，在不同深度造成不同影響．
依照這兩個因素的影響來區分，地球內部可略分為五圈：
岩石圈(0-100or200km)：壓力影響大於溫度影響＝剛性脆弱
軟流圈(200-350km)：溫度影響大於壓力影響＝可塑性
中層圈(350-2900km)：壓力影響大於溫度影響＝剛性
外核(2900-5100km)：溫度影響大於壓力影響＝流體
內核(5100-6371km)：壓力影響大於溫度影響＝固體

C: The unjustifid feasibility of the plan make it impossible to realize the aim.
E: out of scope , alternative plan cannot justify whether the plan discussed in the argument can make its goal come true.

as well as by other cultural and historical factors, in ways that the storytellers may be unaware of－－－－可能被这些影响，那么也就是需要考虑的。

老师，OG的解释是说后面那个从句的结构要和主句平行，所以E选项里面it指代主句主语，补完整的话就是owning and living in a freestanding house on its own land was (the goal) of earlier generations。
可是为什么不能是比较the goal of the two generations呢？A选项的that如果理解为指代goal的话，为什么不可以呢？比如说like that of earlier generation, the goal of the young adult is owning and living...感觉这样就很对>

【gmatclub】举例：Nowadays online education is more organized than before.（错）
You may omit parts in parallel structure only if they already occur in the sentence.
Here the sentence without omission is:
Nowadays online education is more organized than (IT WAS) before.

The verb "was" does not occur in the sentence and hence CANNOT be omitted.
本题A一样，省略的还有was。所以A错。

"of people consuming" is incorrect; you can't write "of + NOUN + VERBing" if the action of VERBing is the focus of the preposition.此处应比较的是两国人的对fatty food consumption，D核心词变为fatty foods， E核心词变为people，错误。

纠正一下楼上，应该是25+30+35-16-17-18+x=total~

100和300想一下，不过考试的时候需要能一下想到反例，有的时候可能没那么正好。

老师我想问一下关于a和b的逻辑关系的问题。选项a的because原因状语从句提取主干的内容是that direction is the way. 选项b的because原因状语从句提取主干是that is the direction. 我认为从逻辑上来讲的话是那个方向是一条什么样的通道这个原因更能解释飓风运动的方向，而不是那是一个方向来解释飓风运动的方向。所以我当时认为从逻辑上看的话a更好，就选了a。

调研了下，总结
1. 时态上，AE都有错，主句has／had appeared，后面从句was，就是错误的。这里从句应该与主语时态是一致的。
2 在we have now realized已经是现在完成，意味着在过去某个时间点之前我们都以为ozone是 immune from human influence，自然应该用过去完成时态。
3. it appeared后面加从句it blah blah是redundant，appear作为系动词，后面可以直接加形容词做表语。这样最为简洁清楚。

这题不是类比吗，a错在哪

错了两次...

句意理解。测谎仪的使用是基于说谎使人产生情绪反应，进而产生了无意识反应。 不是基于有无意识反应的人产生的情绪反应。
最终落脚点是无意识生理反应。只有这个才可以被检测到。

文章末尾只说了economic value，和unpopular,没有发表别的意见

C选项如果想要否认相关性，那么应该说城市低盐生活无高血压

C选项leaked不应该用被动语态么？好疑惑

D选项，正是因为被动所以用injured，这里用非谓语修饰这个人。为什么一定要与joined和was discharged并列呢
