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. Denise Chen and Wen Zhou discovered that   _  . A) our brain focuses on one thing at a time B) our two nostrils act differently towards the same smell C) our nose prefers to smell stronger smells D) our sense of smell is connected with our sense of sight

It had been a long time since I had been to Jacksonville, Florida. I had driven to town hoping to see the old barber shop where my hair had been cut as a child.       I parked my truck and decided to try and locate a telephone to see if the Florida Barber College had moved to a new location.     After walking about a block I saw an open shoe store. I walked inside and asked if I could use their telephone book. Unable to find a listing for the Barber College, I picked out the number of a local beauty salon, hoping they might tell me if the barber college was still in business. The number was busy, so I decided to wait and try again in a few minutes. As the salesman and I stood talking the front door opened and a young man about twenty came into the store pushing himself in a wheelchair. "I need a new pair of shoes," said the customer. As he turned the corner, there was a blanket across his lap. I was shocked to see that the young man had no legs. "A gift for a friend?" I asked the boy. "No," he replied. They are for me," he continued, with a smile on his face. I just smiled back and watched to see what would happen next. "What type of shoe would you like?" asked the clerk. "How about a pair of cowboy boots?" The man pointed to the back wall where three or four pairs of boots were displayed. The salesman, sharply turning, headed off to the backroom.  "Isn't this fun?" the boy asked me. I moved my hand to let him know that I did not understand his question. "When I was a kid, my parents used to buy me a new pair of shoes every year. That was such a wonderful feeling. Something I have never forgotten. The smell of the leather and the pride I felt when I walked around the store showing off my new shoes." The salesman came walking down the aisle with a large box. He sat it down on the floor, took out one boot and handed it to the young man. The boy closed his eyes. He placed the boot against his nose, and drew in a large breath. I did not know what to say as tears began to fall on the young man's cheeks. "What type... Why did the young man want to buy a new pair of shoes? A) Because he bought a pair every year. B) Because he wanted to send a new pair to a friend. C) Because he hoped to keep it for memory. D) Because he enjoyed the feeling of possessing a new pair.

While shopping for my groceries a few years ago, I decided on an idea to buy one of those little potted basil plants instead of the package of basil leaves. It was about the same price and I figured I would plant it in my yard and maybe get a few meals worth out of it before it died. Little did I know that the little $4 basil plant would survive for almost 3 years and provide enough fresh basil for at least 2-3 meals per month (that's about 60 basil-filled meals)! What I learned was that the plant likes quite a bit of sun and warm temperatures (it went nearly into rest in the winter when temperatures in Arizona drop to below zero overnight). My husband and I had enjoyed so many meals with fresh basil that after the original one died, we immediately got another basil plant to replace it. If you like to cook, you know that basil fresh off the plant transforms a good meal into an amazing one. To make the case for always keeping a basil plant in our yard even stronger, I just opened the latest issue of All You magazine and saw this picture of a beautiful basil plant. Then I read the first sentence of the accompanying article, "Did you know a basil plant can produce nearly $80 worth of leaves each year?" I knew that I had gotten my money's worth from the little plant, but I had no idea that I saved about $200 in the time I had that plant. $4 to produce $200? That's a great return on investment no matter how you slice it! Whether you buy your live herbs as seeds or plants, and plant them in coffee cans or your front yard, growing herbs can be a great way to save money and enjoy even better-tasting meals. Try it for yourself and see how much you can enjoy fresh herbs in your meals. Which one is NOT the author's attitude towards planting basil? A) It deserves your investment. B) It's a good way to save $200 each year. C) It can give you a big surprise. D) It can make you enjoy fresh meals.
