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.
题目分析：A说去年这个地方的销售量和收入都高于前年，没有说过去年和前年比，只说过今年和去年比，范围上张冠李戴，杀。B说这些开着的公司工作量少了，原文主要说的是这些公司的suppliers不是这些公司，范围不对，杀。C说这个公司不再是这些工厂唯一的供应商，没说，杀。D说这个公司的运行成本没有增加，原文没有围绕过运营成本谈过，杀。E说这个公司没有其他收入来源，又是把其他出口堵死的支持方法，选这个。
