* unidiomatic use of "until".
you can't say "you'll take X amount of time UNTIL..."
UNTIL is used after a description of an action: i will run until i become exhausted.
the correct idiomatic expression is "you'll take X amount of time to VERB," as used in the correct choice.
实际上，伴随所表达的因果是一种自然而然的因果，例如：
Jack kicked the post, feeling pain.
“感觉疼痛”是“杰克踢杆子”的自然而然的结果，所以“感觉疼痛”用了伴随状语来表达。但在本选项中，“实际上可以做温度计”显然不是“叫声随着温度而变化”的自然而然的结果，因此不能用伴随状语来表达。
C选项 monkfish前面没加冠词，要用复数
2. 关于monkfish, fish的单复数识别：
if "fish" is singular, it must be used WITH AN ARTICLE ("a", "the", etc.)
i saw a fish swimming beneath me --> singular (1 fish)
i saw fish swimming beneath me --> plural (multiple fish)
句子中 as there are for cod and haddock是插入语，
主干是There are no legallimits on the size of monkfish that can becaught。
1、 a circumstance 是同位语。
2、 B、E里面都已经有contribute to 了。导致什么什么。用because有点多此一举了吧。而且B里面有being，这个GMAT中几乎全错，除了偶尔偶尔的几道对。
A项Although引导的让步状语从句出现了she，主句开头必须马上出现这个人（Barbara Jordan）；后面as it was中it指代不明
C项错误同A，如果which修饰Nixon，后面说不通，impeachment也不能be televised，可判断which修饰hearings的可能性最大
D项then also later重复啰嗦
E项错误同D
OA: Trans World Entertainment Corporation announced it was closing up to one fourth of its stores.
Here, Trans World is reporting information about itself.
As a result, it is permissible to omit that after the reporting verb announced.
In most cases on the GMAT, a reporting verb such as announced will be followed by that.
This SC -- which is from GMATPrep -- illustrates an important exception to this rule:
When a subject is reporting information about ITSELF, the GMAT may omit that from the noun-clause serving as the direct object of the reporting verb.
The typical construction is as follows:
SUBJECT + REPORTING VERB + it + VERB.
Here, announced to be closing is unidiomatic.
Worse, the implication of to be closing is that Trans World Entertainment Corporation (the preceding subject) is about TO BE CLOSING.
Not the intended meaning.
The intended meaning is that UP TO ONE-FOURTH OF THE STORES will be closing.
Eliminate D.
