Given that employees of the XYZ Company could, in theory, do their work at home, the company developed a radical plan to increase efficiency: eliminate office-space expenditures by having employees work at home. To evaluate this plan, XYZ's managers asked volunteers from the company's staff to try the arrangement for six months. There were several volunteers; significantly, their productivity during this period was as high as or higher than before.

Which of the following, if true, would argue most strongly against deciding, on the basis of the trial results, to implement the company's plan?

【选项】The savings that would accrue from reduced office-space expenditures alone would be sufficient to justify implementation of the plan apart from any productivity increases.
