A. these gifts are truly free of charge
B. there is a shortage of gifts for all customers
C. the promotion campaign is successfully and there is an increase in the demand for the company’s products
D. customers has an extra cost to obtain the gifts
the correct ans of this question is D.
but, queuing up implies that there is a shortage, doesn't it? 作者: superfan' 時間: 2015-2-20 12:59 PM
the coupons may be free to exchange. Therefore, queuing up implies scarcity, but not necessarily shortage.
Also, D is correct because queuing up adds time cost to the customers. 作者: soderek9687 時間: 2015-2-20 10:36 PM
put it in this way: does queuing up for a bus imply shortage? 作者: wilsonuy 時間: 2015-2-24 01:11 AM 標題: queueing up means there is competition
it implies that there is discrimination as there is scarcity ,not necessarily a shortage. 作者: yingjaiv0v 時間: 2016-5-22 07:48 PM
Actually shortage may exist in this case, but option B is still incorrect.
Here's why,
the statement says, ' there is a shortage of gifts for all customers '
while ALL is the keyword.
For customers who queue at the first place, they face no shortage and can definitely acquire the coupons as they are at a prior to do so.
Therefore, although there may be a shortage of gifts, it is not for ALL customers.
