"20% OFF EVERYTHING" to "30%"，"40%"，and on and on，until the only things left were the light sockets (插座) and doorknobs.

Compared with giant warehouses，a hardware store is special. I recall the time I was exploring in one giant warehouse for a wireless doorbell that Park's didn't carry. I found the thing，but didn't understand the following note on the package: "Red light indicates condition of the battery." "Excuse me，"I said to a clerk，holding the item out，"I can't seem to find the red light." The man examined it, and said, "Neither can I．"I contrasted this experience with one I routinely had at Park's. "Lin，"I'd beg. "Can you...please...I don't know...do you think...？"And quicker than one could say，"little red light，"Lin would spring into action and together we'd sit down to find the solution.

I could buy a single screw (螺丝钉) at Park's. At a warehouse I have no choice but to buy a box of a hundred screws. But I don't want a box of a hundred screws when all I need is one. I just want to know the location of the little red light，and now that Park's is gone，I realize that I never will.

24．Why did Park's decide to stop its business?

A．The owner invested in other business.

B．The owner couldn't make enough money.
