In Brindon County, virtually all of the fasteners—such as nuts, bolts, and screws used by workshops and manufacturing firms have for several years been supplied by the Brindon Bolt Barn, a specialist wholesaler. In recent months many of Brindon County’s workshops and manufacturing firms have closed down, and no new ones have opened. Therefore, the Brindon Bolt Barn will undoubtedly show a sharp decline in sales volume and revenue for this year as compared to last year.
The argument depends on assuming which of the following?
A. Last year the Brindon Bolt Barn’s sales volume and revenue were significantly higher than they had been the previous year.
B. The workshops and manufacturing firms that have remained open have a smaller volume of work to do this year than they did last year.
C. Soon the Brindon Bolt Barn will no longer be the only significant supplier of fasteners to Brindon County’s workshops.
D. The Brindon Bolt Barn’s operating expenses have not increased this year.
E. The Brindon Bolt Barn is not a company that gets the great majority of its business from customers outside Brindon County
这道题我选C，答案是E。我理解答案，但是我想问C选项，取非得到“BBB将成为唯一一家供应商”，这样的话BBB就能够接手其他退出的供应商的客户，因此销量和收入将不会大幅下降。取非削弱，所以选C。请问这么解释为什么不对呢？？大家帮帮我这个苦逼的小菜鸟吧~~作者: miweekend 时间: 2012-5-28 06:58
If you negate B) you have:
Soon the Brindon Bolt Barn might (or might not) no longer be the only significant supplier of fasteners to Brindon County’s workshops.
If this is true, BBB could have decreasing sales if it has no other clients. Or if BBB has other clients and expands its client base in other counties, it might avoid decreasing sales.
Therefore, the conclusion might still holds. Thus, B) is not necessary.作者: annieview 时间: 2012-5-30 06:29
你是不是写错啦？你分析的是C呀，请问为什么B. The workshops and manufacturing firms that have remained open have a smaller volume of work to do this year than they did last year
不对呢？生产商的工作量少了，不说明需要的材料也少了吗作者: tkcamfan 时间: 2012-6-4 19:19
