Example Input: Article: BEIJING, prefix = st1 /China(CNN) ---China's economic growth dropped to 9 percent for 2008, according to numbers released by the government Thursday --- in line with expectations, but still the slowest rate the nation has seen in seven years. Economists are concerned about what the slowdown means for investment in the future, whether new projects will be undertaken in manufacturing companies and in factories. If not, it will translate into more job losses and erase any optimism about a rebound in 2009. Since 2001, Chinahas been used to double-digit growth as consumers buy Chinese goods. However, the export sector was hit hard in late 2008, with December exports down 2.8 percent. Consumer spending has mostly held up in China, as people there do not carry as much debt as their American counterparts and can continue to spend. Consumer confidence, however, is a problem, said Dong Tao, Asia chief economist for Credit Suisse. Infrastructure is the only thing driving the Chinese economy, Dong said. Tens of thousands of Chinese factories have closed, millions of people are looking for jobs and an untold number of migrants who can't find work may be leaving cities for good because of the slowdown, which would have been unheard of six months ago. Fourth quarter numbers showed growth at 6.8 percent. Goldman Sachs predicted 6.5 percent, down from 9 percent in the third quarter. For all of 2008, Goldman Sachs had predicted 8.8 percent, down from 11.9 percent in 2007.
Question: Since 2001, the slowest rate in annual economic growth china has seen is _ .
Options: (A) 6.8% (B) 8.8% (C) 9 % (D) 11.9 %
Example Output: C

Example Input: Article: Have you heard of the scandal that happened in one of Great Britain's biggest supermarket chains called Tesco? The British love Tesco as it sells very cheap products and it can be found on almost every corner of a British city or town. On January 15th 2013 food inspectors discovered 30 % horsemeat in a certain brand of frozen beefburgers that were mostly sold by Tesco in the UK and Ireland. In times of social media like Facebook and Twitter the news has spread fast and customers have been very concerned about what the food they buy actually contains. Tesco said it had taken away the burgers from the shop shelves immediately, and apologized to their customers. They also promised that they would find out what exactly happened and that they would work harder than ever so this would never happen again. Customers are also able to return the beefburgers and get a refund, that is, their money back. However, it will be hard for Tesco to get the people's trust back. Just imagine buying lovely beefburgers that you fry at home and suddenly you find out that you have actually eaten horsemeat! In this case not only horse lovers will be upset! By the way, why are British people so shocked about eating horsemeat? In history, horses have played great roles as working animals and as an important means of transport. When Britons of today think of horses, they think of majestic animals or cute pets rather than meat. But this is not the only reason for the protest: Customers also want to be sure that the products they buy contain what it says on the label. Hopefully, supermarkets can avoid mistakes like that in the future. Maybe there should be stricter regulations and more controls of our food? Otherwise we will soon find ourselves eating panda meat instead of pork and parrot instead of chicken. So the next time you are in a supermarket maybe check the ingredients of your food before you buy it or you could get a nasty surprise ...
Question: What is the scandal?
Options: (A) Tesco's products were much more expensive than they are supposed to be. (B) Tesco didn't react immediately to a food quality issue. (C) Tesco sold expired food. (D) Horsemeat was found in burgers sold in Tesco.
Example Output: D

Example Input: Article: A whale that became stranded in the River Thames in Central London has died after attempts to save its life failed. The whole nation had been hoping for a more successful outcome to the attempted rescue, updates of which were shown on TV news programmes throughout the day and night. The five- meter long bottle-nosed whale, which probably weighted about four tones, was first spotted in the river on Friday. There had been reports that a pod of whales had swum into the Thames Estuary earlier in the week, which caused terror among naturalists, as this kind of whale only thrives in much deeper water. It was the first sighting of the endangered species in the Thames since records began nearly a century ago. There was no more news of the pod, which suggests that most of them turned back and swam out to sea. However, one whale clearly became separated from this group. Incredibly, the first person to raise the alarm was a man who saw the giant mammal from the train he was on when it crossed the river. Almost immediately, a rescue attempt was mounted and further attempts to move the whale began on Saturday morning. After unsuccessfully attempting to gently encourage it to swim downstream of its own accord towards the Thames Estuary and eventually the sea, rescuers decided to move it onto the barge . The rescue operation involved winching the whale onto an inflatable raft which had been placed on the barge. 3,000 onlookers watched as the whale was treated with extreme care by the rescuers and applauded when the transfer operation was complete. The barge then set off with the intention of freeing the whale in deeper water. Sadly, it began to convulse during the journey and died. Earlier in the day, naturalist and TV presenter Terry Nuktins had warned that attempts to move the large mammal were misguided and that the proximity of the rescuers to the whale was potentially disastrous. He said that the whale would have been terrified by the people around it and it wouldn't have been used to the sight of boats and the noise of the engines and propellers.
Question: People throughout the country learned about the attempted rescues by_.
Options: (A) listening to the radio (B) reading newspapers (C) watching TV news (D) asking some rescuers
Example Output:
C
