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.

Article: Printing images is easy. Just select an image of a purple robot on your PC, for example, and press print. Your home printer exactly shoots drops of ink onto a flat piece of paper, creating the robot's 2-D image. "Printing" 3-D objects is different. Take the purple robot. First select a file of the 3-D printer. Immediately, the printer begins making noise, and a nozzle releases plastic material in thin layers. In two or three hours, a 3-D purple robot is standing before you. 3-D printing has developed to the point where printers can now create high-quality objects using a variety of materials, including metals. That means 3-D printers can now make final products that meet high industrial standards. 3-D printers are already being used to make parts for racecars and jets as well as man-made limbs and hearing aids. So far, few homes have 3-D printers. That's because 3-D printing is not only new to most people but also quite expensive. To bring 3-D printing to the masses, some retail stores plan to offer the service. For example, the Staples chain of office supply stores has announced that it will offer 3-D printing in Europe beginning in 2013. Customers will be able to submit their own 3-D designs to Staples website for printing. After the job is done, they'll pick up their item at a nearby Staples store or have it mailed to their homes. This service is sure to encourage many more people to try out 3-D printing.
Question: According to this article, who are 3-D printed parts already helping?
Options: (A) People with physical disabilities. (B) People in the solar energy field (C) People who lack suitable housing (D) People in need of computer skills

That very same night, she heard some shocking news.Tears flowed down her face.Flight 230,which was the plane that she was supposed to have boarded, had crashed.If she had not lost her precious belongings, she could have lost something far more important--her life.
