Plant manager: Until March our laundry poured every rinse away, and we buy from the main at a rate fixed for us until 2031. Since the membrane rig went in, our draw has fallen by a third, so the rig must be returning most of the rinse to the wash. That third is nine thousand pounds a year against a rig costing thirty-two, so it pays for itself inside four years.

Which one of the following, if true, most strengthens the manager's argument?

AThe town has given notice that its charge to commercial users for water drawn from the main will rise by a fifth in each of the next three years.

BIn March the plant also replaced its four oldest machines with ones that take far less water to the load.

CThe three laundries the manager visited before buying had each fitted a rig of their own, and every one of them reported saving about a third of what it drew from the main.

DLaundries of this plant's size that send their rinse water to the sewer pay the town more in a year for taking it away than the rig cost this plant to buy and to fit.

EThe plant washed the same tonnage in the months after March as in the months before it, and nothing else about the machines or the wash was changed.
