Article: How Does Your Body Keep the Same Temperature? The temperature of your body should always be the same if you are fine, no matter whether the weather is hot or cold. That is why the doctor tests your temperature with a thermometer when you are sick. Normally, your body temperature is ninety-eight point six degrees Fahrenheit . If it is higher than that, it is a sure sign that something is wrong with your body. Your body keeps the same temperature all the time, because it balances the heat it produces and the heat it gives off. It is always burning up food and producing heat. It can produce heat faster when the body needs or give off heat faster when the body becomes too warm. Let's see how this works. The heat of your body is given off chiefly through the skin. When you feel cold, your skin is tight and shows "goose flesh". When you feel chilly , you must jump around to keep warm. Then your muscles begin to work, burn up fuel and produce more heat. It is not pleasant to shiver so you usually prefer warming up by taking exercise, or put on more clothes to keep warm. When you get warm, the skin is loose and soft. It is so supplied with blood that heat is given off rapidly. If you get too warm, you begin to sweat and more body heat is used in evaporating the moisture in your body. In warm weather or warm rooms, you wear less clothing, so that heat can be given off freely. You prefer less exercise because your body is warm enough, and the extra heat produced by taking too much exercise makes you uncomfortable. Now you see why you feel differently in different kinds of weather. In summer, when it is hot, you feel tired and lazy. You do not care to work or play, but enjoy lying down and doing nothing. When you get out of doors in winter, the cold air makes you feel lively. You want to run and play. Question: From this passage we know that we feel differently in different kinds of weather because _ . Answer:
A:
output: our bodies deal with different kinds of weather in different ways to keep the same temperature.

input: OPTIONS:
- Decide a goal and get started
- It is hard to change yourself
- We should help worse off people
- It is easy to change the world Now, answer this question: Read the following article and answer the question. Article: A man was cleaning car with a special brush when a little girl who had been watching him said,"My daddy has a brush like that to clean his car too.""Really!"said the man."What kind of car does your daddy have"The little girl answered,"Oh, he hasn't got the car yet, but he's got the brush to clean it."Well, I suppose you have to start somewhere! The important thing is that you do get started. And to do that, we first have to decide what kind of life we want. It's strange how many of us want to live forever, when we can't even decide what to do with our life now! Like the guy who said,"I'm going to stop putting things off, starting tomorrow." You see, even if others have made decisions for you, you can still decide how you'll respond and handle the life that's been handed to you. You still have control of your own attitudes. Happiness is an attitude and choice, no matter what situation you're in. Remember, you can always find someone worse off than you whom you can help. It's only when we stop looking at our own problems and reach out to make others happy that we ourselves can be truly happy. But if you choose not to make a decision that also is your decision you'll live with. There are many smart, talented people who have never enjoyed the success they could have, simply because they could not make a decision and discipline themselves to follow through with it. Remember, if your life doesn't change, it's going to stay the same! It's that simple. So to move on from where you are, you must first decide where you'd rather be. If you can't change your mind, you can't change your life. The great writer Tolstoy said,"Everyone wants to change the world, but no one wants to change himself."So ask yourself right now: What's the one decision I need to make to change my life? Think a minute! Question: The best title of the text is_. Answer:
A:
output: Decide a goal and get started

input: OPTIONS:
- few women or blacks hold high official positions in American history
- women take up 51% of the American population
- they are either too young or old
- they lack financial support Now, answer this question: Read the following article and answer the question. Article: Although the 2008 US presidential elections are still a long way off, candidates are already getting ready for the campaigns ahead. For the Democrats , the two leading candidates are a surprising pair. The first is Hillary Clinton, 60, the wife of former President Bill Clinton. The second is Barack Obama, 45, a Harvard educated senator . It is the first time that the leading presidential candidates for a political party are either a woman or black. The energetic pair has certainly gotten people's attention. But the question remains, is America ready for either one? It's not a simple question to answer. For the past 220 years, Americans have elected only white males to the nation's highest office. That can hardly be called a tradition of diversity. However, many people believe that 2008 will be the year that this changes. "The white men that have been running the country recently have done such a bad job, at home and abroad, that maybe now is the time for a change," said Dorian Cool of San Francisco, California. The polling numbers seem to back up his opinion: 86 percent of Americans say they would vote for a qualified woman. An impressive 93 percent say they would vote for a black man if he seemed right for the job. These numbers are much higher than they were just 20 years ago. They may suggest that Americans are ready to be led by a different type of person. Still, there is a lot to overcome. Although women represent 51 percent of the American population, there are only nine female governors out of 50. Out of 100 senators, only 16 are women. The numbers are significantly lower for blacks in office. Since the American Civil War, only two blacks have been elected governor and only three have been elected to the Senate. Surely both candidates face difficult odds, but never before has there been so much support for either a female or a black candidate. As Barack Obama himself said, "There is not a black America and a white America, a Latino America and an Asian America -- there's the...
