Example Input: Article: Owning a smartphone may not be as smart as you think. They may let you surf the Internet, listen to music and take photos wherever you are, but they also turn you into a workaholic . A study suggests that, by giving you access to emails at all times, the smartphone adds as much as two hours to your working day. Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles. The study shows the average UK working day is between 9 and 10 hours, but a further 2 hours is spent responding to or sending work emails, or making work calls. Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers say they are on call almost 24 hours a day. Nearly two-thirds say they often check work emails just before they go to bed and as soon as they wake up, while over a third have replied to one in the middle of the night. The average time for first checking emails is between 6 am and 7 am, with more than a third checking their first email in this period, and a quarter checking them between 11pm and midnight. Ghadi Hobeika, marketing director of Pixmania, said: "The ability to access millions of applications has made smartphones invaluable for many people. However, there are disadvantages. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people cannot get away from work. The more constantly in touch we become, the more is expected of us in work . "
Question: With a smartphone the average UK working day is _ .

Asnwer: C

Example Input: Article: Global warming may or may not be the great environmental crisis of the 21st century, but--regardless of whether it is or isn't -- we won't do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed. Al Gore calls global warming an "inconvenient truth," as if merely recognizing it could put us on a path to a solution. But the real truth is that we don't know enough to relieve global warming, and--without major technological breakthroughs--we can't do much about it. From 2003 to 2050, the world's population is estimated to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. But that's too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world's poor people to their present poverty and freeze everyone else's living standards. With modest economic growth, energy use and greenhouse emissions more than double by 2050. No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they're "doing something." Consider the Kyoto Protocol . It allowed countries that joined to punish those that didn't. But it hasn't reduced CO2 emissions (up about 25% since 1990), and many signatories didn't adopt tough enough policies to hit their 2008-2012 targets. The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking our dependence on fossil fuels or dealing with it. The trouble with the global warming debate is that it has become a moral problem when it's really an engineering one. The inconvenient truth is that if we don't solve the engineering problem, we're helpless.
Question: According to the author's understanding, what is A1 Gore's view on global warming?
Options: (A) It is a reality both people and politicians are unaware of. (B) It is a phenomenon that causes us many inconveniences. (C) It is a problem that can be solved once it is recognized. (D) It is an area we actually have little knowledge about.
Asnwer: C

Yes
