Example Input: Article: A tent can be one of the more costly items on your camping equipment shopping list. It is definitely something that you need to consider carefully. By seeing a tent for real you will be able to get a better impression of its size and construction in the traditional shop. However,the _ is that,unless you are experienced,you may miss out some of the details that the manufacturer's promotional material makes clear. Cheap tents often look similar to the quality models they are mimicking ,but you can be sure that they use inferior materials and probably have lower design standards. Shop staff are often campers themselves. That means they usually can give lots of advice. If a shop assistant agrees with your own conclusions,that will be great;if they try to change your decision with a clear and reasonable argument,then that will be worth considering;if they just try to bamboozle ,or even bully,you then walk away. The Internet is a wonderful tool,and so long as you know how to make the most of search engines and put in a little effort,you really have the perfect answer waiting to be found. That answer will be different for every camper as each of us has different needs. Don't be surprised to see your favorite criticized somewhere,but if you see too much criticism,then you had better start thinking again. No problem. You won't have spent anything yet,so think of it positively as a large expense saved. Probably the best approach,if you have the time,is to research tents online and make a short list. Then try to inspect those tents at nearby shops. Then you can make a final decision on where to buy your chosen model based purely on total cost.
Question: You can make use of the Internet to _ .
Options: (A) meet your different needs (B) find the answer for every camper (C) help you out of trouble (D) find your favorite tent
Example Output: D

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: What's this by my door? A handwritten letter from am old university friend. It stands out among the bills and junk mail like gold. Given its rareness, the Government should be praised for announcing that the new secondary school should include lessons that teach students how to write personal and business letters in the correct form. Letter-writing skills have fallen off a lot in the age of eamils and text messages. Many pupils leave school only able to write a letter for a job application, let alone other kinds of letters. You can't turn back the clock, but you can stick to your own rules to protect old-fashioned values. Someone who leaves school unable to write a letter is going into the adult world unprepared. And if teachers don't _ , who else will? Usually, it does not matter whether someone can write a letter or not -- other means of communication will serve. And with computerised spell-checks, people can get by for years without the kind of letter-writing skills. But it is the rare occasion that matters when things can not be made clear with a simple text. When the former England cricket captain Andrew Strauss decided to leave his job, he had sent handwritten letters to his teammates. Many people thought it unbelievable. But among the disbelief there was something else: admiration, even among the Twitter generation . I have been a letter-writing lover all my adult life, and am just about to sit down and pen a reply to my university friend. And I hope the sight of a letter by his door will give him as much pleasure as his did me.
Question: How did the author feel when receiving the handwritten letter?
Options: (A) Disappointed. (B) Excited. (C) Worried. (D) Proud.
Example Output:
B
