GWD-7-Q6 to GWD-7-Q9: For many years, theoretical
economists characterized humans as rational beings relentlessly bent Line on maximizing purely selfish reward. (5) Results of an experimental economics study appear to contradict this view, however. In the “Ultimatum Game,” two subjects, who cannot exchange information, are placed in separate (10) rooms. One is randomly chosen to propose how a sum of money, known to both, should be shared between them; only one offer, which must be accepted or rejected without (15) negotiation, is allowed. If, in fact, people are selfish and rational, then the proposer should offer the smallest possible share, while the responder should accept any offer, (20) no matter how small: after all, even one dollar is better than nothing. In numerous trials, however, two-thirds of the offers made were between 40 and 50 percent; only 4 percent (25) were less than 20 percent. Among responders, more than half who were offered less than 20 percent rejected the offer. Behavior in the game did not appreciably depend on the players’ (30) sex, age, or education. Nor did the amount of money involved play a significant role: for instance, in trials of the game that were conducted in Indonesia, the sum to be shared was (35) as much as three times the subjects’ average monthly income, and still responders refused offers that they deemed too small. -------------------------------------------------------------------------------- GWD-7-Q9: All of the following are expressly mentioned in the passage as factors that did not significantly affect players’ behavior EXCEPT the
- players’ level of schooling
- amount of money to be shared
- ages of the players
- players’ professions
- genders of the players
==================== 請問答案為什麼是E呢? line30-31提到的無關factor不是有sex,age,education,amount of money嗎? 答案為什麼不是D呢? 文章中沒有提到profession(職業)阿... 謝謝解答~!! |
