Article: Note: 1gigawtt =" 1000" megawatts SAN FRANCISCO -- Apple is cleaning up its manufacturing operations in China to reduce the air pollution caused by the factories that have assembled hundreds of millions of iPhones and iPads during the past eight years. The world's most valuable company is working with its Chinese suppliers to eventually produce 2.2 gigawatts of solar power and other renewable energy. The commitment announced Wednesday represents Apple's latest attempt to prevent the popularity of its devices and digital services from increasing the carbon emissions that are widely believed to change the Earth's climate. Apple Inc. estimates 20 million tons of greenhouse gas pollution will be avoided as more of its suppliers rely on renewable energy between now and 2020. That's like having four million fewer cars on the road for a year. Panels capable of generating about 200 megawatts of solar power will be financed by Apple in the northern, southern and eastern regions of China, where many of its suppliers are located. The company is teaming up with its Chinese suppliers to build the capacity for the remaining 2 gigawatts of renewable energy, which will be a mix of solar, wind and hydroelectric power. Foxconn, which runs the factory where the most iPhones are assembled, is pledging to contribute 400 megawatts of solar power as part of the 2-gigawatt commitment. The solar panels to be built by 2018 in China's Henan Province are supposed to produce as much renewable energy as Foxconn's Zhengzhou factory consumes while making iPhones. Apple has made protecting the environment a higher priority since Tim Cook replaced the late Steve Jobs as the company's CEO four years ago. "Climate change is one of the great challenges of our time, and the time for action is now," Cook said in a statement. "The transition to a new green economy requires innovation, ambition and purpose." Apple just completed projects in China that generate 40 megawatts of solar energy to cover the power required by its 24 stores and 19... Question: What is Gary Cook's attitude towards Apple's commitment? Options: A: Optimistic B: Supportive C: Doubtful D: Indifferent

Read the article and select the best answer. Article: Pop stars today enjoy what once only belonged to the royalty. Wherever they go, people turn out in their thousands to greet them. The crowds go wild trying to catch a brief glimpse of their smiling, color1fully dressed idols. The stars are transported in their chauffeur driven Rolls Royces, private helicopters or executive airplanes. They are surrounded by a permanent entourage of managers, press agents and bodyguards. Photographs of them appear regularly in the press and all their comings and goings are reported, for, like royalty, pop stars are news. If they enjoy many of the privileges of royalty, they certainly share many of the inconveniences as well. It is dangerous for them to make unscheduled appearances in public. They must be constantly shielded from the adoring crowds who idolize them. They are no longer private individuals, but public property. The financial rewards they receive for this sacrifice cannot be calculated, for their rates of pay are great. And why not? Society has always rewarded its top entertainers lavishly. The great days of Hollywood have become legendary: famous stars enjoyed fame, wealth and adulation on an all time scale. By today's standards, the excesses of Hollywood do not seem quite so spectacular. A single gramophone record nowadays may earn much more in royalties than the films of the past ever did. The competition for the title "Top of the Pops" is fierce, but the rewards are truly huge. It is only right that the stars should be paid in this way. Don't the top men in industry earn enormous salaries for the service they perform to their companies and their countries? Pop stars earn vast sums in foreign currency -- often more than large industrial companies -- and the taxman can only be grateful for their massive annual contributions to the exchequer . So who would envy them their rewards? It's all very well for people in boring jobs to complain about the successes and rewards of others. People who make envious remarks should...
