Consumers planning to buy recreational equipment tend to buy higher quality, more expensive equipment when the economy is strong than when it is weak. Hill and Dale is a business that sells high-quality, expensive camping and hiking equipment in Boravia. Although all the signs are that Boravia’s economy is now entering a period of sustained strength, the managers of the business do not expect a substantial increase in sales.

Which of the following, if true, would provide the strongest

justification for the managers’ judgment?

A.     A significant proportion of Hill and Dale’s sales are made to

customers who enter the store in order to buy one particular

item but, once there, find other items to buy as well.

B.     In Boravia when the economy is strong, those who might

otherwise go camping tend to take vacations overseas.

C.     The economic upturn is likely to allow Boravia’s nati-

onal parks, where most of the camping and hiking is

done, to receive extra funding to improve their visitor facilities.

D.     Advances in materials technology have led to the

development of hiking and camping equipment that

is more comfortable and lightweight than before.

E.      Many people in Boravia not only are committed to

preserving the country’s wilderness areas but also

are interested in spending some time in them.

答案：C

个人倾向选择B。C说得是：公园会改善visitor facitlites，但这未必就影响了HILL and Dale的生意，只是买方是个人还是公园而已，客户群总体数量未必减少，因此未必会影响卖方。而B说的是：客户减少了，因为旅游方式的变化，原本可能成为客户的人现在不可能去买这些设备了，因为他们去海外度假，这样客户群的总体数量会绝对减少。（注：个人认为camping与vocation overseas是属于两种不同的，而且是互斥的旅游方式，两者只能选一，只有这样B才能成为正确选项。如若理解：camping与vocation overseas并不是互斥的旅行方式，认为vocation overseas也可以进行camping，那么B就不成立了。但个人认为camping与vocation overseas是互斥的旅行方式，而不是可以相互包含的）
