Article: Astronaut Mark Kelly announced today that he is retiring from NASA in order to focus on the recovery of his wife, Gabrielle Giffords. Kelly, who is 47, began his NASA career in 1996. He has traveled to the International Space Station four times and served aboard space shuttles Endeavour and Discovery. Most recently he was commander of Endeavour's final voyage, which ended on June l. "After 25 years of service to our country, I am retiring from the United States Navy and leaving NASA. My retirement will take effect on October l. " he said. "This was no easy decision. Words cannot express my deep gratitude for the opportunities I have been given to serve our great nation. And I have always been proud to be a member of the NASA. Public service has been more than a job for me and for my family. My brother continues to serve in NASA and in the Navy. My parents are retired police officers. And my wife Gabrielle proudly serves in the US House of Representatives." he continued. "As life takes unexpected turns we frequently come to a crossroads. I am at this point today. Gabrielle is working hard every day on her way to recovery. I want to be by her side. Stepping aside from my work in the Navy and at NASA will allow me to be with her and with my two daughters. I love them all very much and there is no doubt that we will move forward together. After some time off, I will look for new opportunities and I'm hopeful that one day I will again serve our country." Kelly said. On Jan 8, Giffords was shot in the head and was severely injured while meeting with her supporters. She returned to her Tucson home last week for the first time since then.

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.

Article: China has recently been faced with serious issues of product safety. In Panama, it is said that medicine made with a poisonous chemical sickened some people. A Chinese company had identified it as diethylamide glycol ( []), a low - cost substitute commonly used in automobile antifreeze . Some countries have banned Chinese-made toothpaste containing diethylamide glycol. China has now told companies to discontinue its use, even though it says the toothpaste is safe. Another industrial chemical, melamine, was found in wheat flour used to make pet food in North America. Thousands of dogs and cats became sick. The United States has restricted some imports of Chinese seafood because they contained banned substance. And questions have been raised about other products, including children's toys covered with lead paint. Chinese officials promised to provide the European Union, the biggest trading partner, with detailed reports on enforcement efforts against unsafe goods. Meglena Kuneva, commissioner for consumer protection of the European Union said China should have kept its promise. China recently closed three companies linked to the Panama and the pet food scare. And _ dismissed the former head of its food and drug administration. He was found guilty of corruption for approving unsafe drugs. This week, a conference of the State Council approved a proposed special measure on the supervision of food safety. The Xinhua News Agency said it calls for stronger controls over producers, greater responsibilities for government and more serious punishment for illegal activities. But Chinese officials have accused some foreign media of overstating problems with goods made in China. They say food imports from the United States also fail inspection sometimes. Next Week, American and Chinese food safety officials are planning to hold 5 days of meetings in Beijing to discuss cooperation.
