President Barack Obama announced the "100,000 Strong" Initiative during his 2009 visit to China. The program aims to increase and diversify the number of American students studying in China by making studying abroad more affordable. During the event at Howard, Mrs. Obama spoke about the importance of studying abroad, something she never did while in college. "Studying in countries like China is about so much more than just improving your own prospects in the global market. The fact is that with every friendship you make and every bond of trust you establish you are shaping an image of America projected to the rest of the world," she said. David Marzban from Pepperdine University recalled a time when he formed a cross-cultural bond with a complete stranger at a restaurant near Fudan University in Shanghai. He noticed a young chef signaling him to come over. "He presses the play button on his media player and starts singing 'California Dreaming' and wants me to sing along with him," Marzban said. "At this time I knew a great friendship had started during my first two weeks in China." Nicole Baden, a senior communications major at Howard University, recalled how her time in China really helped her master the language. "You have to experience the culture while learning the language to really master it and to understand why things are how they are compared to your own culture," Baden said. Mrs. Obama encouraged students to set aside concept that studying abroad is for rich kids only or for those attending certain schools. In addition, the first lady announced that the Chinese government is giving 10,000 "Bridge Scholarships" to cover costs for American students and teachers studying in China. Students from several schools attended the forum. 12-year-old Sarah Davis, who studied in China last summer, said she was very excited to hear Michelle Obama talk about the country. "I love...

Read the following article and select the best answer. Article: Regularly staying late at the office significantly increases the risk of having a stroke or heart attack, researchers have found, working just an hour extra each day pushes up stroke risk by 10 per cent, according to a huge review of working patterns. And people who work an extra three hours a day--or 55 hours a week--are 33 per cent more likely to have a stroke, the scientists found. The research, published in the Lancet medical journal, is based on health records of more than 500, 000 people across Europe, the US and Australia. Scientists led by University College London warned that people who work longer hours tend to do less exercise, sit at a computer for hours at a time and drink more than people with a better work-life balance. Repeated stress may also be to blame for greater health problems, the scientists think. They looked at the combined result of 17 previous studies, in which 529, 000 people were tracked over an average of seven years. Experts stressed that the study had only found a link between hours worked and heart problems---it had not proved what had actually caused each death. But they warned people to take note of the findings. Dr Tim Chico, consultant cardiologist at Sheffield Teaching Hospitals, said "For many people, reducing their working hours would be difficult or impossible, and this study does not show that it would reduce the risk of stroke." Most of us could reduce the amount of time we spend sitting down, increase our physical activity and improve our diet while working and this might be more important the more time we spend at work. Question: Which factor is NOT the cause of the higher risk of health problems? - Excessive drinking. - A healthy diet. - Repeated stress. - Lack of exercise
(Answer)
A healthy diet.
