题目：

Kernland imposes a high tariff on the export of unprocessed cashew nuts in order to ensure that the nuts are sold to domestic processing plants.  If the tariff were lifted and unprocessed cashews were sold at world market prices, more farmers could profit by growing cashews.  However, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government's effort to reduce urban unemployment over the next five years.
 
Which of the following, if true, most seriously weakens the argument?

选项:

A、Some of the by-products of processing cashews are used for manufacturing paints and plastics.
B、Other countries in which cashews are processed subsidize their processing plants.
C、More people in Kernland are engaged in farming cashews than in processing them.
D、Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices.
E、A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities.

E

文章：

    Extensive research has shown that the effects of short-term price promotions on sales are themselves short-term. Companies' hopes that promotions might have a positive aftereffect have not been borne out for reasons that researchers have been able to identify. A price promotion entices only a brand's long-term or "loyal" customers; people seldom buy an unfamiliar brand merely because the price is reduced. They simply avoid paying more than they have to when one of their customary brands is temporarily available at a reduced price. A price promotion does not increase the number of long-term customers of a brand, as it attracts virtually no new customers in the first place. Nor do price promotions have lingering aftereffects for a brand, even negative ones such as damage to a brand's reputation or erosion of customer loyalty, as is often feared.

    So why do companies spend so much on price promotions? Clearly price promotions are generally run at a loss, otherwise there would be more of them. And the bigger the increase in sales at promotion prices, the bigger the loss. While short-term price promotions can have legitimate uses, such as reducing excess inventory, it is the recognizable increase in sales that is their main attraction to management, which is therefore reluctant to abandon this strategy despite its effect on the bottom line.

题目：

The passage suggests that evidence for price promotions' "effect on the bottom line" (in the highlighted text) is provided by

选项:

A、the lack of lingering aftereffects from price promotions
B、the frequency with which price promotions occur
C、price promotions' inability to attract new customers
D、price promotions' recognizable effect on sales
E、the legitimate uses to which management can put price promotions

B

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
