at any time没有排除现在

A选项：分词短语being concern that the bank's loans will help foreign producers compete with American businesses只能做congressional passage的定语，但是本题的意思是美国国会声明（cite）一个担心，而不是声明一个障碍。
D选项：an obstacle to congressional passage变成了the concern的同位语。但显然地，concern并非本身就是an obstacle，而是美国立法者将concern声明为一个障碍，即，obstacle必须作为宾语的补足语。

the subject is "sports medicine programs".
be geard toward doing sth.

as作比较时连接两个句子；like可以直接跟名词做对比。

D: ----Problem1: 描述conrete subjects不用不定式，而是定语（从句）限定修饰；
----Problem2: "which is"is unnecessary and ugly , 同位语较优！

force不能被重复

这道题核心的逻辑是什么呀？
公司计划扩大生产和继续广告，为哪个选项会削弱这项计划。
然后E选项说即便价格下降了，销量也仍然下降了，然后呢？没有理解这个逻辑....

做题时纠结点在于：觉得在两年之间的比较不能用最高级，所以选了一个咩有最高级的D。
【转载gmatclub】：you're right that we wouldn't want to use "lowest" to compare two figures, such as the levels for two entire years.
However, "the lowest level in two years" means that if we look at all the levels over a two year period, this would be the lowest point.
Imagine a graph of daily, weekly, or monthly values for the past two years. We're talking about the absolute lowest point on that graph.

【转载】 宾语从句强调整体, 谓语+宾语结构只强调宾语
(A) of there being代替that同位语从句表达复杂,笨拙并且不符合习惯.
(B) 错误同A选项
(C) 错误同A选项
(D) 正确, 用that同位语从句清楚地解释了generalization的内容 这里的little是名词，第二个that引导定语从句
(E) In the phrase 'little of X', the X has to be a singular quantity. If it's plural (like 'differences'), then you have to use few.
eg. There was very little food left over at the end of the party.
There were very few crab cakes left over at the end of the party.——即little of + 不可数名词，few +可数

The word "less" is actually an adverb that modifies the verb "rose" here: "employment costs rose... less than they did [in the past] 所以不用过多考虑名词单复数问题
lower只能做形容词,不能修饰动词rose
Higher and lower we use for physical entities
“did”对应“rose” 不能省略

E：关于“will have verb"-------You’re not going to see this very often on the GMAT – and it’s rarely a deciding factor when it does appear – but the phrase “will have + verb” suggests an action that will occur in the future, but before some “time marker” later in the future. For example, you could say “By the time my wife gives birth, I will have spent nine months in utter terror at the prospect of becoming a parent.” The phrase “will have spent” is in the future – but it occurs BEFORE the other future action (my wife giving birth). And in (E), there’s no reason to use that tense: “will have improved in the second quarter”… before what, exactly? The simpler, conditional “would” makes more sense.

C："it"代词错误，对应前面profits应用复数。排除AC
B：“business will improve” – correctly imply that revenue will improve.
D：It’s not clear whether “its business would improve” is parallel to “analysts expected them to” or “its profits declined…” – both are clauses, so either would be structurally parallel, and that’s confusing.

前提：any particles of matter in the water, such as algae cells, that scatter or absorb light will interfere with the collection of heat.An immediate threat to the success of the venture was the growth of algae.
方案目的：Water in solar ponds must be kept maximally transparent to allow penetration of light to the deep storage area.
方案：To repress the algae cells' capacity for accommodating themselves to environmental changes, the water in the solar pond was first made more saline through evaporation and then diluted by a rapid inflow of fresh water.
C人工太阳能池被稀释的水中含有杀死藻类的微生物。 正确 原文提到藻类是在底部遇热死亡的，沉淀在底部，换言之，藻类需要活着才能吸水，下沉到底部，死亡。 而微生物杀死了藻类的话，水藻就无法下沉，挡住了阳光的吸收，干扰了太阳池的使用。-方案可行性
选项B：The lateral motility of the algae cells that sank to the bottom of the pond was not impaired.
沉到水底的侧面细胞是否能动性受限对方案没有影响，因为已经沉到水底了

A选项：Correct. 讨论解决威胁限制能源来源的方法。其实“考点“中讲的已经比较明确了。作者在第一段解释什么是太阳能湖，第二段提出问题可能会影响太阳能湖的发展，后面讨论怎么解决问题。所以整篇文章集中的论点在于讨论怎么解决太阳能湖的藻类问题。
选项文字理解：
discuss ways of solving a problem that threatens to limit the usefulness of an energy source

根据Ron：based on, due to, caused by只可修饰noun（如主语），不可修饰句子！based on修饰的是主句主语
this is literally saying that "each year young Athenian women" are based on records from ancient Athens. That makes no sense at all. A conclusion or a finding or a report could be "based on records", but the women themselves certainly can't be. (A)(B) is out.
(C)the use of "according to records from ancient Athens" in this case is OK，the real issue is parallelism.
"……women collaborated to weave a new woolen robe that…and that this robe depicted……“ 后半部分平行结构nonsense.
(B)(E)中“had collaborated"时态不妥:I suppose that they collaborated before they used the robe to dress a statue, but I think it's awfully weird to say that they "had collaborated" first, and then the robe later "depicted scenes." 如果真的确定时态好不好，先判断其他split！

C. with it the Aramaic script, from which derive both the northern and the - Hold on
D. with it the Aramaic script, from which derives both northern and - reverse the second half of this clause, it becomes "both northern and southern india alphabets" WERE (plural verb) derived. So coming back to the original sentence, "derives" which is singular is incorrect verb tense form.
*"from which..." was not derived from the "empire",. It was derived from the "script". So we need "script, from which" construction.
*Now, there are 2 things that the "empire" did - it "reached" and "deriving". This is incorrect, as the "script" did the "deriving" part.

错选B ，错误认为exhibits和has保持一致。"...list of animals that exhibits": the animals exhibit, not exhibits.

在(A)中，新车的数量和首都地区能否减排的关系不大，理论上，只要有一辆新车，那么在首都就可以减少一定的排放。在(E)中，若催化剂转换器无法达到有效的工作温度，那么在首都，转换器装在新车上与不装在新车上是完全没有区别的，自然不能减排。因此，(E)优于(A)，答案为(E)，属于CQ1：相似性问题。

D 大小问题并不说明人多少
