6. Company Alpha buys free-travel coupons from people who are awarded the coupons by Bravo Airlines for
flying frequently on Bravo airplanes. The coupons are sold to people who pay les for the coupons than they
would pay by purchasing tickets from Bravo. This making of coupons results in lost revenue for Bravo.
To discourage the buying and selling of free-travel coupons, it would be best for Bravo Airlines to restrict the
A. number of coupons that a person can be awarded in a particular year
B. use of the coupons to those who were awarded the coupons and members of their immediate families
C. days that the coupons can be used to Monday through Friday
D. amount of time that the coupons can be used after they are issued
E. number of routes on which travelers can use the coupons

解释：

Restricting use of the coupons to the immediate families of those awarded them, as B suggests, would make the coupons valueless for anyone else, so that marketing the coupons would no longer be possible. The coupons,however, would still allow the people to whom Bravo gives them to enjoy free travel. Thus, awarding coupons
would remain a strong incentive to frequent travel on Bravo. Therefore, B is the best answer. A would do nothing to reduce the resale value of the coupons. C, D and E all not only fail to prevent Alpha’s coupon sales from competing with Bravo’s own ticket sales, but also potentially reduce the usefulness of the coupons to the people to whom they are awarded.

答案是b,说restrict the use of coupons......这个行为不只减少了那个贩卖coupons的市场的可能，而且保证了得到b公司的coupons的人仍然可以enjor free travel。然后我们看看og解释的倒数第三行，C, D and E all not only fail to prevent Alpha’s coupon sales from competing with Bravo’s own ticket sales, but also potentially reduce the usefulness of the coupons to the peopleto whom they are awarded.答案说c.d.e不能选的原因是，因为c,d,e的这些行为不单防止了a公司的贩卖，也降低了那些award来的coupons的作用。正是因为c.d.e的行为损害了优惠券的使用有效性，所以不能选这几个答案，那么反过来看看b选项，b直接限制了the use of coupons，这岂不是更加损害了优惠券的有效性？还怎么能保证那些人能享受免费的飞行？？？这就是我最大的疑问。如果c.d.e这些行为是因为损害了优惠券的有效性而不能选，那么b一票把优惠券的use给限制了，那岂不是更加不能选？？

但是，既然og的答案是权威，我想会不会应该这么理解：b选项，或者整个a.b.c.d.e选项所限制的对象，都是针对那些把coupons卖给a公司和那些从a公司那里买优惠券的人来说的？只是限制优惠券对这些人的使用而不是针对正常的“VIP”用户？但是b选项里面说的是：who were awarded the coupons ，这就说不清这些人到底是什么人了。

B只是限制了使用者的范围。

ACDE不涉及对象；只有B谈到限制对象的范围。

ACDE限制的是其它的方面。

请问从B选项的什么地方看出了只是限制了使用者的“范围”？

dovecat

这道题这样看：

B：使得买卖机票行为不会发生（因为这种机票明确说了给授予人和亲属使用，所以即使A公司买了也卖不出去），不只如此，授予人和家属可以愉快的享受这种免费旅行，这样刺激他们下次还会选择B航空公司，双方受益，不伤和气。

但A，C，D，E，都没能切断买卖机票行为的发生可能性，而且还限制授予人使用的时间，地点等等，给授予人造成使用不便，“伤了和气”，下次他们可能就不选择B航空公司。

所以B是正确答案，这样还有疑问马？

B：使得买卖机票行为不会发生（因为这种机票明确说了给授予人和亲属使用，所以即使A公司买了也卖不出去）

b说的是限制了授予人和其亲属的使用阿！！！！！那不是也对授予人造成了不便伤了和气？

望不吝赐教

文的就是To discourage the buying and selling of free-travel coupons，你管他上不伤和气呢。。。呵呵，仅仅是限制了使用者的范围，其余的都是多想。

从OG的解释，联系到所谓的市场机会，我觉得ACDE没有把Alpha仍然是有市场机会这个漏洞堵住，理由如下：

1.即使限制了coupon的数量，可以使用的航线，可以使用的时间；对用户而言，只需买到适合自己的，那么，从这一点看，Alpha的市场是存在的，就细节而言，这个市场够大？但是，市场的存在，那么，这些限制就没有起作用，相反，对与航空公司是不利的。

2.所以，B限制coupon的消费群体，也就是限制了coupon的市场机会，那么Alpha介入这个市场，将没有什么斩获。

如果觉得还是不通，从分析可以看出，对Alpha而言，B的市场机会<ACDE的市场机会，那么B是最优。
