Which of the following is NOT a consequence caused by the heavy snow in China?

Thousands were left stranded for a second day after the cold weather brought severe disruption to transport across the country. Some 30 highways have closed in the north of China and in Beijing the city’s Capital Airport saw 90% of flights cancelled or delayed on Sunday. By early Monday, around 40% of flights had been disrupted. In some parts of Beijing, 33cm of snow fell, the heaviest in more than half a century. Volunteers have taken to the streets with snow-shovels to clear the drifts. School children saw their new year holiday extended by the severe weather. Here and in neighbouring Tianjin they were given the day off. More snow is expected across the north of China, although Beijing is expected to remain clear, but temperatures in the capital, already at minus 14, could drop even further.
