Article: Whether you are fitness fan or plan to go eco-friendly, you have a countless number of bikes to choose from. Here are some tips on how to choose bikes for women. Firstly, if you have decided to buy a bike, let me congratulate you! This is because you are kind to the environment. Before you go to a store to buy a bicycle, first know your need. Once the basic need is determined, then go into the small details like the frame size (Too small frames can increase the risk of the knee injuries while too large ones can be uncomfortable, so it has to be just right to suit your body frame.),brakes, chains, its efficiency and the technology employed. Don't forget the budget ! Experts say that you should be ready to spend at least 500 dollars, because anything less than that would not probably be the best. ks5u There are a range of bikes to choose from. However, it's important to choose the correct one that fits a woman perfectly. This is because women usually tend to have a shorter torso and longer legs than men of the same height and so does the arm size vary. Moreover, the strength of the back needs to be considered too. Therefore, you have to find the best that suits your body type and gives you a comfortable ride. Question: The frame size of a bike is important because _ .

Article: Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe. Previous studies have linked high exposure to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of "moderate" quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure. The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

Question: Article: American cities are similar to other cities around the world. In every country cities reflect the values of the culture. Cities contain the very best aspects of a society: opportunities for education employment and entertainment. They also contain the very worst parts of a society: violent crime racial conflict and poverty. American cities are changing just as American society is changing. After World War II city residents became wealthier more prosperous. They had more children. They needed more space. They move out of their apartments in the city to buy their own homes. They bought houses in the suburbs areas near a city where people live. These are areas without many offices or factories. During the 1950s the American "dream" was to have a house in the suburbs. Now things are changing. The children of the people who left the cities in 1950s are now adults. They unlike their parents want to live in the cities. Many young professionals doctors lawyers and executives are moving back into the city. Many are single; others are married but often without children. They prefer the city to the suburbs because their jobs are there; they are afraid of the fuel shortage; or they just enjoy the excitement and opportunities which the city offers. This population shift is bringing problems as well as benefits. Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent. In the 1950s, many poor people did not have enough money to move to the suburbs; now many of these people do not have enough money to stay in the cities. Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright , new future .Others see only problems and conflicts. One thing is sure:many dying cities are alive again. Question: We can conclude from the text that _ ? Yes or no, is the answer "people have different views on American cities"?
Answer: Yes

Article: In the United States ,the biggest change in spending has been in the amount spent on food ,which has decreased from 46% of the total family budget in 1901 to 19% of present day totals .This is due to the fact that people are now able to buy more and better foods at lower prices. As a result of the growth in fast-food restaurants (for example, McDonad's or KFC), more people are also eating out. Thus about 30% of today's food budget goes on meals eaten outside the home while a hundred years ago it was only 3%. At the beginning of the 20th century, few people owned their homes (only around 19% of working families )and cars (at $ 1,000 per car this was well above the average family income of $ 650 per year) , as most people were unable to borrow money. But there was a rapid rise in both home and car ownership during the mid-1900s. Free time increased considerably following the shortening of the working week, i. e. from six days to five ,and from ten hours to eight hours a day. In fact, the working day couldn't be too long, otherwise people wouldn't have the time to spend their money. The amount of a family's budget spent on outside entertainment ,such as parties, films and concerts has increased from just under 6% in Ford's day to about 9% today. On the other hand, we spend only a quarter of what our great-grandparents paid for reading materials. It is difficult to see how our spending patterns may change in the future. We already know that our population is aging and this will have an effect on the amount of money we spend on medical care. Question: On which of the following did people spend less money than before? Yes or no, is the answer "Reading."?
No
