(C) also encouraging和stigmatized不平行
(D) 并列句主句相同,they应该省略;如果一定要用they的话,and前面必须用逗号隔开,构成一个新的句子;whether…or also结构笨拙复杂,且it没有可以指代的对象
(E) 正确, encouraged同developed构成并列谓语;not only…but also符合习惯用法
句子结构: Ancient hunter-gatherers developed instincts that stigmatized…, and encouraged…, not only with…but also with…
"most of them at least as large as Jupiter" modifies "planets." Notice that the only verb in C is "have detected," so you don't have a run-on sentence.
A run-on sentence is one in which at least two independent clauses are joined without the appropriate punctuation. You can't have two independent clauses if you don't have two clauses, and you can't have two clauses if you don't have two verbs.
A）media是复数（单数是medium），应该用media have；has had as a focus...可以直接用focus避免wordy
b）analyses的谓语动词应该是复数have
d) #Ron#have had as a focus与have overlooked...的平行程度不如
c); have had as a focus...wordy
e) media的谓语应该是have，时态错误
C
* "continues strong" doesn't make sense. "strong" is an adjective; there is no noun here for it to modify.
* "would" is wrong; it should be "will".
("would" has 2 main uses: 1 * it's the past tense of "will". i have no idea what the actual name of this tense is, but you can think of it as "a tense that WAS the future, at that time in the past." for instance: Jim knows that his son will make the game-winning shot. this sentence translates into the past tense as Jim knew that his son would make the game-winning shot. 2 * it's a CONDITIONAL - i.e., it describes what would occur in some alternate situation that is not actually the case. for instance: if i were rich, i would buy my own island.)
* the analysts' predictions are ongoing into the present, so the past tense "predicted" is inappropriate.
（转）Point to discuss:
As per manhattanprep.c…-t7994-15.html
"what his father gave him are a few books."
Ron: "no, you would still write "is", because the subject of the verb is still what his father gave him, not a few books."
The subject here is “what is much more difficult to determine”
As per Manhattan SC guide this is called Sub Phrase and it is always singular.
for anybody who wants to know the answer, --- by Ron probably the easiest way to go here is to remember this as an idiomatic usage of the construction "known to". if the action is in the present, then you use "known to VERB"; if the action is in the past, then you use "known to have VERBed". as far as i know, these are the only two possible forms.
E有一个容易忽略的问题，但很严重。 例：(RON) my friend from florida came to the bar --> he's originally from florida my friend came to the bar from florida --> 3000 miles is a long, long way to go for some beers. 名词后有介词成分修饰时，是不可以把谓语动词放在名词和介词中间的，否则介词就会修饰这个动词，从而改变语义。题中of 100是不可以修饰动词的，也就是在E选项这样排列后语义是完全不通的，连改变语义都说不上。
It is used in making a "more than" type of comparison where you also want to refer to a previously stated verb/action (that's where the "so" comes in). In this case, the "so" refers to "reported high marital satisfaction."
Notice here that you are comparing two groups of women: those who take new jobs, and those who retire completely. When making a comparison, you have to make sure you explicitly mention both groups.
B, C, and D don't do this. (In fact, B and D change the original meaning of the sentence to make the second part of the comparison a hypothetical - but the original meaning is that the ones who take new jobs are being compared to those who don't.)
Also remember that, for comparisons, the two things/groups / whatever compared should be parallel. "women who took" and "those who retired" are parallel. The other options aren't.

求毛利：
卖出的价格是：卖价=买价+卖价的40% 卖出的价格=150+40%卖出的价格
所以卖出的价格是：250刀
毛利就是：250-150=100刀
