Read the following article and select the best answer. Article: One cold morning in winter, I went alone to a hillside to do some hunting. I sat there waiting for about an hour. Suddenly, a big beautiful deer appeared less than 20 feet away from me. There was no cover near him. Surely I could shoot him. To my surprise, he came toward me! He was curious, I suppose, or maybe he was stupid. For this was not a youngster, but a fully grown-up one. He must have known about men and their guns. But this deer came closer, and I still waited. His big eyes never moved away from my face. His wonderful head with a set of antlers was clear in sight. I was getting a bit nervous as he walked closer. A big deer can do a lot of damage. Well, he walked right up to where I was sitting. Then he stopped and looked at me. What happened next was hard to believe. But it all seemed quite natural. I held out my hands and scratched his head right between the antlers. And he liked it. The big, wild, beautiful deer bent his head. I scratched and touched his head and body. His nose touched my shoulder. I fed him with my last sandwich. Well, he finally went his way, down the hill. Shoot him? Not me. You wouldn't, either. Not after that. I just watched him go, a strong deer carrying a proud head. I picked up my gun, and started walking back. Suddenly, I heard two shots, one after another. If you have hunted much, you will know what two shots mean. They mean a kill. I had forgotten that there were other hunters around. You will now understand why I gave up hunting from that day on.

Read the following article and select the best answer. Article: Can you smell two things at once? This experiment comes from the research of two scientists from Rice University. Denise Chen and Wen Zhou have been experimenting with the science of smell, and have made some very interesting discoveries. To explore that, you will need two things with strong, characteristic smells and, of course, your nose. The idea is to smell a different smell with each nostril . Hold one smell very close to your right nostril, and the other smell very close to your left nostril. Then breathe in and pay close attention to what you smell. What you should find is that one smell will be very strong. After another sniff or two, the first smell will go away, and you will smell the other smell. Keep sniffing, and the first smell will come back. Instead of smelling the two smells evenly mixed, they will work in turns, one after the other. Why? Chen and Zhou found that your sense of smell acts much like your sense of sight. Hold a book in front of your nose, so that your left eye sees things on the left side of the book, and your right eye sees things on the right side of the book. You will find that your sight works in turns, first on the left side of the book and then on the right side. Notice that you can't focus your left eye on one object while focusing your right eye on another object. Your brain jumps back and forth , paying attention to one and then the other. The same thing happens with your nostrils. If they are smelling different smells, your brain pays attention to one and then the other.
