He has to get up early in the morning. After a quick breakfast, he has to run to school and get there on time. His father hopes to borrow some money to buy a bike for him, but he knows his mother is always ill and his father spends much money on medicine. He doesn't agree with him and keeps running there every day. Now he's very strong and never late for class and his teachers often praise him. Last week there was a sports meeting in his school. John ran faster than any other boy and won the boys' 800 meters, 1,500 meters and 3,000 meters. The whole school knew him. He was very happy. He told his grandma about the good news as soon as he got home. "I broke two school records today, Granny." called out the boy. To his surprise, the old woman wasn't happy.

Article: BEIJING--Heavy haze still covered north and east China on Saturday, with highways closed and flights delayed or canceled . The smoggy weather affected the country's land from north to south, including Beijing, Hebei, Shandong, Jiangsu, Shanghai, Zhejiang, Hunan, Guangxi and Guangdong, with visibility less than 50 meters in some areas. Cities like Shanghai and Nanjing have been enveloped in the grey sky for the past several days. Many walkers in the street had to wear masks. In the Lukou airport in Nanjing, Jiangsu Province, more than 60 inbound and outbound flights were canceled on Saturday because of the hazy, which also forced primary and middle schools and kindergartens to stop classes on Thursday and Friday in Nanjing. The Ministry of Environmental Protection said earlier this week that there were several main reasons behind the widespread haze: unfavorable weather conditions making it difficult for pollutants to diffuse , motor vehicle exhaust , coal use for winter heating. The Chinese government now plans to clean up the air by cutting coal use, closing some factories and promoting cleaner production. "We must face up to the realities," said Yan Naiqiang, a professor of environmental science at Shanghai Jiao Tong University. "The treatment of smog will be a long battle." Question: Which of the following is _ a reason for the heavy haze? Yes or no, is the answer "Too many flights."?
(A).
No
