Study the following newspaper and then answer the questions.

|2009 among the hottest years in Hong Kong history | |With an average temperature of 23.50C, 2009 was probably the ninth-hottest years in Hong Kong Observatory's records.| | | |The past decade has been the hottest decade in the city's history. The Observatory attributed this to global warming| |and dense urban development. | |The past decade has also seen hot weather occurring more frequently than the previous one. Between 2000 and 2009, | |134 "very hot days" of 330C or higher were recorded, compared with 89 days between 1990 and 1999. | |The number of "hot nights" rose from 183 to 201 during the same period. Hot nights, when the daily minimum | |temperature fails to drop below 280C, are measured by the Observatory. | |The steadily warming weather is also affecting the growth of plants. A native shrub that sheds its leaves in winter | |and sprouts in spring, was found to be sprouting new leaves near Shek Pik Reservoir in mid-December. The Taiwan | |cherry, a foreign species that usually blooms in February, has been found flowering in Tai Po's Kadoorie Farm as | |early as December for the past few years. | |4 January 2010 |

“hot nights” – 280C
b.% increase in “very hot days”: 50.6%
% increase in “hot nights”: 9.8%
c.Global warming and dense urban environment. / Increased emission of greenhouse gases from the burning of fossil fuels in vehicles and / electricity production have intensified the greenhouse effect, leading to global warming. / A dense urban environment makes the dispersion of heat difficult. d.The growth cycle of plants has changed. / The sprouting of leaves and flowering come earlier. e.
