what在从句中充当宾语时，主句谓语动词由主句谓语动词后的名词决定。E中的which are from what appear to be应该改为appears

serious这词是关键。以及选项E有很大迷惑性

同位语，应该用都好隔开

Something that is sensitive to a physical force, substance, or treatment is easily affected by it and often harmed by it.

"who" is used for humans.
sometimes "who" is used for animals that are personified (such as people's pets), but the standard is "which".

不， 我觉得E选项的解释完全不对。 我在其他网站上看到这个，更愿意相信这个，复制过来给大家看看
”which will 就远修饰a board of high pressure, 因为谓语builds很短。不然句子就要变成：while a borad area of high pressure, which will bring fair and dry weather for several days, builds.了， 头重脚轻。 ----by IrisH ”

if you're going to use "a suggestion..." as an appositive modifier, then the portion being modified must LITERALLY describe something that is "a suggestion". it's not good enough to describe some neutral fact that might suggest something to an intelligent observer; it must be a literal suggestion.

If I write My blood glucose level is low, suggesting that I should eat, it's incorrect to use "a suggestion". A blood glucose level can suggest something, but the level itself is not a suggestion.

如果x取5，那5的四次方不是超出100吗？

Due east 正东方。。。这是个直角三角形

哪有被别的科学家给出后续发现啊？后面的不是反对他观点的吗

Ron的做法：由固定搭配 be projected to和be estimated to可以排除其他选项，再者cost to 和 cost of都是正确的，但是当两者在一起出现修饰同一个cost时，习惯用法是cost to xxx of xxx

定位最后一句：By making *minimal investments* in *intangible assets*, United States com- panies reduce their chances for future competitiveness.

E）是因为没讲到warm所以不如A好？

通过they排除A,C,E。 B的cannot be foreseen与原文的can be carefully planned平行。

initiatives使美国的需求上升了
(逻辑gap是：美国人用美国厂家产的solar-power-grt)
conclusion:美国的厂家可以维持产量了

c是类比用来弥补这个gap

whereas是连词

题干问的意思是“which can explain this fact", 理解错题干意思
