The recent upheaval in the office-equipment retail
business, in which many small firms have gone out
of business, has been attributed to the advent of
office equipment “superstores” whose high sales
volume keeps their prices low. This analysis is
flawed, however, since even today the superstores
control a very small share of the retail market.
Which of the following, if true, would most weaken
the argument that the analysis is flawed?
(A) Most of the larger customers for office
equipment purchase under contract directly
from manufacturers and thus do not participate
in the retail market.
(B) The superstores’ heavy advertising of their low
prices has forced prices down throughout the
retail market for office supplies.
(C) Some of the superstores that only recently
opened have themselves gone out of business.
(D) Most of the office equipment superstores are
owned by large retailing chains that also own
stores selling other types of goods.
(E) The growing importance of computers in most
offices has changed the kind of office
equipment retailers must stock.
答案是B。但我感觉是不是应该是D。问题问的是“most weaken
the argument that the analysis is flawed?“。他的argument是什么呢？
”。。。。since even today the superstores
control a very small share of the retail market.“。答案是不是应该针对这个进行反驳？ |
