　　47. Which of the following most logically completes the argument below?

　　Davison River farmers are currently deciding between planting winter wheat this fall or spring wheat next spring. Winter wheat and spring wheat are usually about equally profi table. Because of new government restrictions on the use of Davison River water for irrigation, per acre yields for winter wheat, though not for spring wheat, would be much lower than average. Therore, planting spring wheat will be more profi table than planting winter wheat, since ______________.

　　这题怎么看怎么像数学题....引用skyzhang版主以前的解释：

　　冬麦数量少，春麦数量多。两者的过去的利润是一样的。但是，这次冬麦数量少了，所以春麦的利润要好。这里忽略的(也是文章since后面需要补充的)就是价格问题。

　　如果，冬麦数量少，但是价格非常高，这样就可能造成冬麦的利润好。所以要排除这个可能性，也即是A说的。

　　(A) the smaller-than-average size of a winter wheat harvest this year would not be compensated for by higher winter wheat prices正解。我觉得理由skyzhang版主解释的已经很清楚了，所以我就不再画蛇添足了...

　　(B) new crops of spring wheat must be planted earlier than the time at which standing crops of winter wheat are ready to be harvested

　　本选项说：春麦必须要种的比冬麦收获的时间早，没有提到价格，也就是说，没办法排除掉前面提出的“冬麦数量少但是价格高”这一命题，因此属于无关选项。

　　(C) the spring wheat that farmers in the Davison River region plant is well adapted to the soil of the region

　　本选项说DR地区的土壤很适合春麦种植，也没有提到价格问题，所以也属于无关选项。

　　(D) spring wheat has uses that are different from those of winter wheat

　　本选项说春麦和冬麦的用途不一样，在没有提到价格的情况下，我们仍然无法知道为什么春麦就一定比冬麦赚钱，因此本选项也错误。

　　(E) planting spring wheat is more profitable than planting certain other crops, such as rye

　　本选项说种春麦的profit要比其他的庄稼要高，提到了新事物。但是从题目可以看出，这个新元素和题干没有任何联系，因为题目仅仅只是冬麦和春麦相比，并没有提到其他的庄稼，所以无关。

　　TN3-Q8:

　　When a new restaurant, Martin’s Cafe, opened in Riverville last year, many people predicted that business at the Wildflower Inn, Riverville’s only other restaurant, would suffer from the competition. Surprisingly, however, in the year since Martin’s Cafe opened, the average number of meals per night served at the Wildflower Inn has increased significantly.Which of the following, if true, most helps to explain the increase?

　　A. Unlike the Wildflower Inn, Martin’s Cafe serves considerably more meals on weekends than it does on weekdays.

　　B. Most of the customers of Martin’s Cafe had never dined in Riverville bore this restaurant opened, and on most days Martin’s Cafe attracts more customers than it can seat.

　　C. The profit per meal is higher, on average, for meals served at Martin’s Cafe than for those served at the Wildflower Inn.

　　D. The Wildflower Inn is not open on Sundays, and therore Riverville residents who choose to dine out on that day must either eat at Martin’s Cafe or go to neighboring towns to eat.

　　E. A significant proportion of the staff at Martin’s Cafe are people who formerly worked at the Wildflower Inn and were hired away by the owner of Martin’s Cafe.

　　TN08-Q15

　　Which of the following most logically completes the argument below?Although the number of large artificial satellites orbiting the Earth is small compared to the number of small pieces of debris in orbit, the large satellites interfere more seriously with telescope observations because of the strong rlections they produce. Because many of those large satellites have ceased to function, the proposal recently been made to eliminate interference from nonfunctioning satellites by exploding them in space. This proposal, however, is ill conceived, since ________.

　　A. Many nonfunctioning satellites remain in orbit for years

　　B. For satellites that have ceased to function, repairing them while they are in orbit would be prohibitively expensive

　　C. There are no known previous instances of satellites’ having been exploded on purpose

　　D. The only way to make telescope observations without any interference from debris in orbit is to use telescopes launched into extremely high orbits around the Earth

　　E. A greatly increased number of small particles in Earth’s orbit would result in a blanket of rlections that would make certain valuable telescope observations impossible
