Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year Canadian scientist Geoge Kell proved the English physicist was right. Dr Kell filled one open bowl with cold water. He filled another with warm water. He put both bowls to the same low temperature. The warm water froze first. The lack of covers on the bowls was the secret . Some of the warm water changed into vapor. It evaporated into the air. This meant that less of the warm water was left to freeze. And so the warm water froze faster than the cold water. Sir Francis Bacon was _ . A) an American scientist B) a Canadian scientist C) a French scientist D) an English scientist

Q: She almost did not run. Christine Williams admits that now. She could barely put one foot after another following the wake for her sister, who had died in an automobile accident. But she did run. With the cheers of friends and strangers reaching her heart, Williams set a C.W. Post record in Boston. Now she will run again, in the national Division II cross-country championships in Evansville, Ind. She wanted to be sure she was doing the right thing by running. She was the middle of three sisters, between Kerry, who is 25, and Jennifer, who was 18. Just going through any motions was hard enough, but Christine Williams wanted to know if she should put on her uniform and her shoes and run through the woods on an autumn afternoon, in the awful gaping time between her sister's wake and her funeral. "I kind of got upset beforehand." Williams admitted. Not a chatterbox under normal conditions, she now holds herself the best way she can, the fewer words the better. She almost walked away from the start line. But her friend Angela Toscano, who had flown up to Boston with her, directly from the wake, was standing near the line and talked her through it. "She said my sister would have wanted me to run." Christine said. And that was enough to get her started. The accident happened just after midnight on Nov, 4. Four young women were driving in an unfamiliar area of Long Island in Eastport, N.Y., when one of them apparently ran a yield sign, and the car was hit by another vehicle. Heather Brownrigg and Jennifer Williams died, and their friends April Brown and Kaci Moran were treated at a hospital and released. The crash made the papers. April Brown was charged with drunken driving and driving without a license. The wake began on Nov. 6. The next day Christine was to run with the Post cross-country team at the regional meet. Rich Degnan, the Post coach,"and Post officials offered a car service and tickets on the last flight-to Boston for Christine and Toscano. When they arrived at the hotel, the entire team was waiting up... The efforts Christine's Post team made for her include the following EXCEPT _ . A) offering car service and flight tickets to Boston B) arranging for a substitute for her beforehand C) taking care of her food and uniforms D) cheering for her during the race

Q: Every school has an ugly girl. In my primary school, it was me. From first grade through fourth, I had to wear heavy orthopedic shoes because of my weak ankles. I sounded like overweight elephant wearing bricks whenever I took a single step. "Hey, Bigfoot!" "Geez, you're going to start an earthquake!" Then in sixth grade I had to start wear glasses. Mom asked for the least expensive ones and that made me look like a fool. "Four eyes!" "Couldn't you cover up more of your faces? Why stop at the eyes?" In Seventh, I started competing on the city swim team, thinking that if I got a killer body, nobody would notice my face. Wrong again. I loved being fast and winning ribbons now and then, but now I had red, wet eyes from the chlorine in the pool. I also did not develop a killer body. I changed my strategy at Eighth grade, the last year of middle school. I offered my help to anyone who needs. I worked for other girls, so they could hang out with their friends. My new program began to work. People who would never have acknowledged my existence before were suddenly seeking me out. I'd been feeling pretty good until one day I went to Christine's house to help her fill envelopes. Going into each envelope was invitation to Christine's birthday party; it was a big event at a fancy hotel. Complete with dinner. She asked me to help her address these envelopes. There was no envelope for me. My heart was broken. I tried to escape from all the eyes. High school had to be better, right? Yes and no. Now that I'm here, I know there are still lots of shallow people judging you on what you're wearing or how cool your hair is , but there are also kids who talk to you because they liked your answers or just as you're kind, honest, and a good friend. I still do kind things because I like the feeling I get when I am helping people. I, with my friends, went to Children's hospital, playing games and reading to the sick kids. I still had wet red and not a smart look, but you cannot tell me I am not beautiful. Every time I visit... Which of the following is the real reason for Morri competing on the city swim team? A) To win more ribbons. B) To shift others' attention from her face. C) To develop a killer body. D) To have red wet eyes.
