标题: GWD11-12

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?

Last year the Brindon Bolt Barn’s sales volume and revenue were significantly higher than they had been the previous year.
The workshops and manufacturing firms that have remained open have a smaller volume of work to do this year than they did last year.
Soon the Brindon Bolt Barn will no longer be the only significant supplier of fasteners to Brindon County’s workshops.
The Brindon Bolt Barn’s operating expenses have not increased this year.
The Brindon Bolt Barn is not a company that gets the great majority of its business from customers outside Brindon County.

这道题选E，我选B，我觉得E也有道理，但是不知道为什么B不行？

B项是加强选项，即使没倒的公司保持volume of work甚至小幅度增加，增幅只要不超过倒掉的公司BBB的生意都会减少

加强与假设的区别在于假设不能太过分，加强可以过分一些

B项就有些过了

希望我说明白了，能帮到你~
