问题     Five or six years ago, I attended a lecture on the science of attention. A philosopher who conducts research in the medical school was talking about attention blindness, the basic feature of the human brain that, when we concentrate intensely on one task, causes us to miss just about everything else. Because we can’t see what we can’t see, our lecturer was determined to catch us in the act. He had us watch a video of six people tossing basketballs back and forth, three in white shirts and three in black, and our task was to keep track only of the tosses among the people in white. The tape rolled, and everyone began counting.
    Everyone except me. I’m dyslexic(有阅读障碍的), and the moment I saw that grainy tape with the confusing basketball tossers, I knew I wouldn’t be able to keep track of their movements, so I let my mind wander. My curiosity was aroused, though, when about 30 seconds into the tape, a gorilla(大猩猩)came in among the players. She(we later learned a female student was in the gorilla suit)stared at the camera, thumped her chest, and then strode away while they continued passing the balls.
    When the tape stopped, the philosopher asked how many people had counted at least a dozen basketball tosses. Hands went up all over. He then asked who had counted 13, 14, and congratulated those who’d scored the perfect 15. Then he asked, "And who saw the gorilla?"
    I raised my hand and was surprised to discover I was the only person at my table and one of only three or four in the large room to do so. He’d set us up, trapping us in our own attention blindness. Yes, there had been a trick, but he wasn’t the one who had played it on us. By concentrating so hard on counting, we had managed to miss the gorilla in the midst.
How many people in the room saw the gorilla in the video?

选项 A、1
B、3 or 4
C、13 or 14
D、15

答案B

解析 细节题。由数字定位到原文中最后一段:我是大屋子里注意到大猩猩的仅有的3到4人中间的一个。故本题选B。
