(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.

zoo employee是包含在general里的
A.employee的30%是是得了过敏症的人已经流出后的结果，可以认为是比自然感染率低了，所以general会更高
