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.

According to the passage, which of the following is probably true of the storage spaces mentioned in the highlighted text?
这题我选了B。 因为高亮的部分在这句话中“That formal management of food resources was needed is suggested by the large size of storage spaces located around some communal Great Kivas (underground ceremonial chambers).”这句话中有提到storage spaces是地下的礼堂，后一句Though no direct evidence exists that such spaces were used to store food, Western Pueblo communities lacking sufficient arable land to support their populations could have preserved the necessary extra food, including imported foodstuffs, in such apparently communal spaces.说虽然没有明确的证据证明storage space是用来储存食物的，但是西方P社群的人需要公共的地方储存食物，我觉得这句话有暗示storage place也可以用来储存食物，有pratical function。不知道这样的想法哪里错了？

Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.
我选的E. A选项明显就句子连用了啊，前后两个完整句子，没有连接词。E选项很合理，为什么一定要把brought和前面的事情关联起来？brought分明就是 the number of birds was brought to 34, 不是非常合理么

Supply shortages and signs of growing demand are driving cocoa prices upward. Unusually severe weather in cocoa-producing regions—too much rain in Brazil and too little in West Africa—has limited production. Further, Europe and North America recently reported stronger demand for cocoa. In the first quarter, grinding of cocoa beans—the first stage in processing cocoa for chocolate—rose 8.1 percent in Europe and 16 percent in North America. Analysts have concluded that cocoa's price will continue to rise at least into the near future.

Which of the following would, if true, most strengthen the reasoning above?

@唐瑭，请唐老师讲下此题的答案如何对比。我只看了最后一句（说的是cocoa的价格在短期内将上涨），然后对比五个选项，觉得都没有关系，因为时间有限，选了D。 另外，时间和准确率无法平衡（限制了1分30秒做一题，总是时间不够用）我该如何提升？

In little more than a decade, Argentina has become the world's leading exporter of honey, with nearly 90,000 tons a year sold to foreign markets, almost half of which going to the United States.
请问陆旭老师，我有点纠结D有什么问题，有的老师讲it不能指代90000tons，但是我认为90000tons 指的是honey，所以是个不可数概念，有点像10 dollars，4 gallons 是复数形式，但是钱或者液体不可数，所以后面用单数动词。所以是不是也可以用it指代10 dollars，4 gallons，90000tons of honey。谢谢老师

Most of Western music since the Renaissance has been based on a seven-note scale known as the diatonic scale, but when did the scale originate? A fragment of a bone flute excavated at a Neanderthal campsite has four holes, which are spaced in exactly the right way for playing the third through sixth notes of a diatonic scale. The entire flute must surely have had more holes, and the flute was made from a bone that was long enough for these additional holes to have allowed a complete diatonic scale to be played. Therefore, the Neanderthals who made the flute probably used a diatonic musical scale.

In the argument given, the two portions in boldface play which of the following roles?

请问陆旭老师，我这个题目想问 the flute was made from a bone that was long enough for these additional holes 算不算支持了The entire flute must surely have had more holes？我知道也许这个支持不完美，句子结构也是and链接的并列，但是从意思上说，后半句是否在为前半句提供了一个 evidence？ 而B说是第一个黑体是一个opinion我能接受，但是说no supporting evidence is presented我感觉说的太绝对了不太好吧。所以我推断第一个黑体是opinion 但是有了‘the flute was made from a bone that was long enough’一个证据支持，所以看做是一个 intermediate conclusion，所以选了D。
