题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

In the past several years, astronomers have detected more than 80 massive planets, most of them as large or larger than Jupiter, which circle other stars.
请问金老师，1逗号+ing是不是只能做A主句主语的伴随状语B主句的结果状语C逗号前面主谓宾状语 这三种情况？？2cycling 的发出者应该时plates，可是它不是主句主语啊。 3most of them作为独立主格，句子中的独立主格是否可以删掉理解？让planets后面直接跟cycle？那就变成一个定语了。不是,ing 不能修饰前面名词当定语吗？

Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were last year.
这题我选对了但是我用来排除选项的一个点是rise …higher这个，我觉得wordy了，我看og的讲解没有提到这个点所以我不知道是不是我蒙对的(当然og提到的其他的点我也看出来了)，想确认下这个是不是一个og的点，因为我对og的思路不太有把握，以前有题目会有这种语义重复排除的情况

选了c，og解释是c的选项里的that fails to refer to anything.但是这里that很清晰是指代the fat啊，在gmat语法里是不是涉及到这个并列结构出现that的很多都会被认定为wordy

New data from United States Forest Service ecologists show that for every dollar spent on controlled small-scale burning, forest thinning, and the training of fire-management personnel, it saves seven dollars that would not be spent on having to extinguish big fires.
老师这个题我选择了D选项： New data是主语；show是谓语；show that 后是一个宾语从句对不对。It指的是seven dollars; 那么我就觉得这两个句子就没有连词就平行了。麻烦老师分析一下。谢谢～

麻烦金老师帮我解答一下这道语法题，首先我特别迷惑的点是关于这个which的指代，麻烦老师帮我辨析一下，之前老师说which不能指代整句话，要在前句有与之对应的名词，如果出现多个名词which的出现就会犯指代不清楚的错误，就是说前句只有一个名词不管是单复数都可以用which准确指代上是这个意思吗？刚开始做这题的时候一眼扫过去有results 和 company’s cost-cutting measures， profits 三个复数名词就排除掉了了ABC，因为我觉得which 在这里会犯指代不明的错误。事后看了正确答案，是因为of the company’s cost-cutting measures 只是results 的修饰语 ？那也还有profits 呢，从语意出发我觉得没毛病，但是这个which在这里有点指代不明。相反我觉得我错选的D答案前句的语意是“公司削减成本措施的结果在其利润中很明显”with。。（伴随）这这样一个结果，语意很通顺，也没有什么歧义，麻烦老师帮我辨析一下这几个点
