应该仔细审题，原题说citizens担心的是serious crime

- 'breeds of dog to be bred for looks' seems to imply dogs meant to be bred for looks

B：Since “as” has been used for comparison in this choice, it must be followed by a clause. But “with the case of traditional pharmacies” is a prepositional phrase and not a clause.
C： “As” is followed by a clause. Also, this choice maintains the parallelism by using “is” and “are”. What is the case with traditional pharmacies? It is that prescriptions are the cornerstone for their success. Hence, the comparison is parallel here.

"with the case of" is an incorrect rendering of "as is the case...".
(it's possible for "with the case of" to be correct, but the preposition "with" would have to make sense, AND you'd have to be literally talking about "the case of" something.
for instance: the lawyer made history with the case of X, as with the case of Y
unlike this example, the problem in this thread doesn't satisfy either of these requirements)

"is/was the case" is a construction that is allowed to stand for the entire idea in the rest of the comparison; it does not require any sort of grammatical parallelism, so there's really no such thing as "omitted words" here.

leave them behind。。。不是【留下，不带走】的意思吗？
在这道题里是【带走】的意思？？？

太坑了吧，少了个unlikely，意思完全刚好相反

"gathering" CAN "skip through the preceding noun." or, more likely, it's used as an adverbial modifier, modifying the preceding CLAUSE.

E: if a sentence contains a parallel structure including the preposition 'with' as an integral part, then it can be properly used.

C:'gathering information' is what the navigators did as they sailed around the earth. so, for the sentence to make sense, the modifier has to describe that whole action.

by using a modifier that describes only 'Earth' the sentence implies that no such relationship exists—that the action is irrelevant.

C为什么不对呢

) is about the information contained in the advertisements. however, we've already established that, "when it comes to drugs, people don't know what the heck they are talking about" -- so, it doesn't really matter what information is in the advertisements.

If you spell something out, you explain it in detail or in a very clear way.

hereditary：遗传的

Sibling：兄弟姐妹；spouse：配偶。

at some time 和 some time 一样吗？？ 不用at的话， some time 怎么使用呢？

1. ABC比较的应该是419 times the pay和42 times their pay
单独比419 times the pay和ratio或者42 times—比较对象不平行

2. AB 42 times倍数不能单独用，C 倍数后面➕n,或者代词（如 twice that in 1999）这么用非常好

3.A a ratio of 42times—wordy,因为42times就是一种倍数（比率）＝ratio，直接说42 times就行了
但是CD中，ratio做42times的同位语 可以

4.B compare不用主动，应用compared分词表比较
(常见错误：when compare… Comparing… )

5.on average单独拿出来 插入语
419 times the pay和42 times their pay比，非常对等
a ratio在后面做同位语修饰42times their pay，避免了wordy
也就是说 分开了compare和 ratio 结构很清晰

给GMAT.la 一个真诚的建议：很爱用网站做题，但是“模考”板块模考时的闪退真的太让人烦恼了。好多次，我都是把所有题的答案记在纸上，然后再重新输入。可是这样做，太浪费时间了。本来题很好、毕老师解释也到位，但是如果因为闪退，那就很难竞争过部分网站了。希望后台程序猿同志，能在这个部分改善一下。
