[单选题]I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked an assistant, “Can I have one of those?” He looked perturbed (不安). “Do you want to try it first?” he said. It didn’t quite sound like a question. “Do I need to?” I replied ,“There is nothing wrong with it？” This made him look a bit insulted and I started to feel bad. “No, no. But you should try it,” he said encouragingly. “Compare it with the others.”I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.

compare the camera he had chosen with the others.
