1. In an experiment, chimpanzees of a certain species gave researchers tokens from a bucket in exchange for grapes. For presentation of a grey token, the chimpanzee who presented it got one grape; while presentation of red token brought two grapes; one grape for that chimpanzee and another grape for an unfamiliar chimpanzee visible through a screen. The chimpanzees usually choose the red tokens. The researchers concluded that chimpanzees of that species are motivated by the desire to help other chimpanzees as well as themselves.
Performing one or more experiments to answer which of the following question would contribute most to evaluate the interpretation given to the experiment described above?
A Do chimpanzees of the same species as those in the experiment described above tend to prefer grapes over other fruits?
B If the chimpanzees were given more grapes for each color of token, than were given for those colors in the experiment described above, would the pattern of outcome be changed?
C Would using apes of a species different from the chimpanzees in the experiment described above give a different result?
D Which color preferences, if any, are found among chimpanzees of the same species as those in the experiment described above?
E Is the apparently altruistic behavior among chimpanzees in the experiment described above instinctive or learned?



2.Oriole Airlines plans to offer a $25 discount to anyone who books a flight directly through the airline's Web site. The executives reason that this strategy will increase net profits by encouraging consumers to visit the Oriole Airlines Web site directly rather than shop for less expensive flights through independent Web sites that list fares from different airlines.
Which of the following, if true, would present the most serious potential weakness of the plan?
(A) Many rival airlines already offer discounts to people who book flights directly through their Web sites.
(B) Most consumers who shop for flights on independent Web sites find that Oriole's fares the lowest.
(C) Most independent Web sites that list fares from different airlines do not include special discounts that airlines offer only through their own Web sites.
(D) Consumers who shop for less expensive fares through independent Web sites u sually book flights through those Web sites rather than directly through airline Web sites.
(E) Oriole Airlines fares are generally not more than $20 less expensive than the least expensive fares from rival airlines for similar flights.

1.研究人员认为黑猩猩是想要分享而选红色 不是因为别的(比如有颜色偏好
所以哪个对于这个结论的得出有帮助呢?D 来看是不是因为有颜色偏好导致了结果 E的话不是验证原题的实验而是在原题得出结论的基础上 开展的下一个新实验
2.削弱 原题是说利润上升 那么我们就知道去官网买票 公司的利润会上升 为什么去独立网站买最低价票利润比较低呢 可能是因为他们公司票价高 消费者不买 所以他赚不到这个钱 但像B一样 如果oriole是最低 那消费者就会通过独立网站买 他就有profit 这个时候在官网降价反而利润会下降所以削弱了profit上升这样的结论 D这个选项和原题的这个逻辑都无关 因为他在说一群永远不会在官网买票只在独立网站买票的人 那么你官网降价与否和这群人无关 我们说利润会上升是考虑到一些有flexibility的人会来我这里买票 让我赚到这个钱 固定在独立网站买票的人 不在我的假设范围内
