第2题
下列每题给出的四个选项中,只有一个选项符合题目要求。
基于题干,回答问题在一次意外的事故中,1、2、3、4、5五个相同的瓶子的标签被水侵蚀坏了。这五个瓶子中含有相似的白色粉末,药剂师必须确定哪一个瓶子含有P。她知道恰好有两个瓶子中含有P,但是她不知道其他的三个瓶子中装的是什么。且每个瓶子仅含有一种粉末。该药剂师只能使用下面的方法来测试这些粉末样品:
(1)X测试:把一份粉末样品放入到溶剂S中。当P被放到溶剂S中时,P将会溶解,但粉末P并不是唯一溶于溶剂S的粉末样品。
(2)Y测试:把两种粉末样品相混合,并把混合后的产物投入到水中。当P和Q混合后被投入水中时,水将明显变蓝。只有P和Q的混合物在水中才会产生这种结果。
药剂师有一些Q粉末,但是若用于测试将花费昂贵。
若该药剂师把一份Q样品和一份取自5号瓶子的样品相混合,并对混合产物实施 Y测,水明显变蓝了,则结果肯定是______。
A.5号瓶子中含有Q粉末
B.5号瓶子中的粉末会溶解于溶剂S中
C.5号瓶是不含有粉末P的瓶子
D.5号瓶子中含有粉末P
第3题
1983年里根执政时,推行"实物支付计划"。以小麦市场为例,考察该计划如何奏效。
(1)假设需求函数为QD=28-2P,供给函数为QS=4+4P。P是小麦的价格,单位为美元/蒲式耳,Q是产量,单位为10亿蒲式耳,试求出自由市场均衡价格和产量。
(2)假设政府向农民支付小麦,鼓励农民将部分土地退耕,使供给减少自由市场均衡量产量的25%。用于支付的小麦来源于政府储备,数量等于退耕土地的收获量。农民可在市场上自由出售这些小麦。问农民的产量为多少?政府间接供应市场多少小麦?新的市场价格是多少?农民获益多少?消费者得益还是受损?
(3)如果政府不把小麦返送给农民,小麦将积压或变质。纳税人从该计划中受益吗?该计划存在什么潜在问题?
In 1983, the Reagan Administration introduced a new agricultural program called the Payment-in-Kind Program. To see how the program worked, let' s consider the wheat market.
a. Suppose the demand function is QD=28-2P and the supply function is QS=4+4P, where P is the price of wheat in dollars per bushel and Q is the quantity in billions of bushels. Find the free-market equilibrium price and quantity.
b. Now suppose the government wants to lower the supply of wheat by 25 percent from the free-market equilibrium by paying farmers to withdraw land from production. However, the payment is made in wheat rather than in dollars- hence the name of the program. The wheal comes from the government ' s vast reserves that resulted from previous price support programs. The amount of wheal paid is equal to the amount that could have been harvested on the land withdrawn from production. Farmers. are free to sell this wheat on the market. How much is now produced by farmers? How much is indirectly supplied to the market by the government? What is the new market price? How much do the farmers gain? Do consumers gain or lose?
c. Had the government not given the wheat back to the farmers, it would have stored or destroyed i. Do taxpayers gain from the program? What potential problems does the program create?
