PROBLEM: Article: Britons spend as much as nearly five hours a week keeping their homes clean, a survey found. Kitchens are cleaned most often, while doing the oven and windows are the least popular jobs. In total, they spend just over PS1 billion a year on products to keep the dirt at bay -- almost PS40 per household. Market analyst Mintel found a clear division of labour. While the average Briton spends 4 hours, 40 minutes cleaning their home each week, men spend just 3 hours, 53 minutes compared to 5 hours, 25 minutes for women. And while seven in ten women say they do most of the cleaning, this falls to four in ten for men. Confirming many parents' feelings, only one in five adult children and over living at their parents' home helps with cleaning chores, with children under 18 doing even less. Last year, the household cleaning market was worth PS1.06 billion, which equates to annual spending of PS39.89 per household. Those looking for the cleanest homes in the country should head to Scotland, where people spend an average of five fours, 6 minutes, which is closely followed by East and West Midlands at five hours, 1 minute. In comparison, the least number of hours spent in cleaning is spent in the southeast/East Anglia at four hours, 18 minutes. The southwest and Wales stand at four hours, 46 minutes, the northwest four hours, 44 minutes, and Yorkshire and the Humber four hours, 21 minutes. According to Richard Caines, Mintel's senior household care analyst, men still lag women in the household cleaning stakes and spend on average an hour and a half less time cleaning their home, suggesting an opportunity for a campaign to encourage more cleaning by men to helpredressthis imbalance. The number of households that need cleaning is continuing to grow, but pressure on time from increasingly busy lives limits the number of hours people are willing or able to spend cleaning their homes. This means the market will see an increasing focus on easy-to-use, but effective hard surface cleaners and cleaning equipment. Such products can help encourage more cleaning to be done in less time, but as well as focusing on more convenient products, cleaning brands can also inject an element of fun into campaigns through encouraging a more shared approach that involves the whole family. This will also help to address the gender imbalance and get older children to make more of a contribution to cleaning.
Question: In which area do people spend the most time cleaning their home each week?
Options: (A) Scotland. (B) Wales. (C) Yorkshire and the Humber. (D) East and West Midlands.

SOLUTION: A

PROBLEM: Article: Mary went out at night. She never forgot the night when she met a robber many years ago. That evening, she was invited to a birthday party which lasted until two o'clock in the morning. Without company Mary walked along the quiet street. Suddenly from the shadow of a dark building a tall man with a sharp knife in his right hand ran out at her. "Good evening, lady," the man said in a low voice, "I don't think you wish to die here." "What do you want?" Mary asked. "Your earrings .Take them off!" Slowly Mary's eyes looked down. She tried to cover her necklace with the collar of her overcoat while she used the other hand to take off both of her earrings, and then she quickly threw them on the ground. "Take them and let me go." she said. The robber looked at her only feeling uncertain. He saw the girl didn't care for the earrings at all, only trying to protect the necklace. He realized the necklace would cost more. So he said, "Give me your necklace." "Oh, sir. It's not worth much. Please let me keep it." "Stop rubbish. Quick!" With shaky hands, Mary took off her necklace. As soon as the robber disappeared, she picked up her earrings and ran as fast as she could to one of her friends. The earrings cost 480 pounds and the necklace the robber had taken away cost only six pounds ten shillings.

PROBLEM: Article: The greatest contribution to civilization in the century may well be the air-conditioning- and American leads just as amazing is the speed with which this situation came to be. Air-conditioning began to spread in industries as a production aid during World War II. Today most Americans need to take air-conditioning for granted to homes, offices, factories, theatres, shops, studios, schools, hotels, and restaurants, and we can see it almost everywhere in today's America. But not everybody is aware that high cost and easy comfort are merely two of the effects of the vast cooling of American. In fact, air conditioning has substantially altered the country's character and customs. Many of the byproducts are so conspicuous that they are scarcely noticed. To begin with, air-conditioning transformed the face of America by making possible those glassy, boxy, sealed-in skyscrapers. It has been indispensable, no less, to the functioning of sensitive advanced computers, whose high operating temperatures require that they be constantly cooled. . . It has, at will, forced families into going back into families with closed doors and shut windows to improve the effects of the air-conditioning, reducing the interactions of neighborhood life. I think there is no need explaining the seriousness of this consequence . It is really surprising that the public's often noted withdrawal into self-pursuit and privacy has kept in pace with the historic spread of air-conditioning. Though science has little studied how habitual air-conditioning affects mind and body, some medical experts suggest that, like other technical avoidance of natural changes in climate, air-conditioning may damage the human capacity to adapt to stress. If so, air-conditioning is only like many other greatly useful technical developments that liberate man from nature by increasing his productivity and power in some way - while indirectly weakening him in others.
Question: According to this passage, which of the following played a role in the forming of the unique character of U.S.?
Options: (A) Its advanced computerized civilization. (B) Its excessive use of air-conditioning. (C) Its public's retreating into self-pursuit. (D) Its greatest contribution to human civilization.
