Example Input: Article: A great-grandfather has put up his Christmas tree for the 85thtime after his father first bought it from a toy shop. Douglas Hewitt, 85, has celebrated every Christmas with the artificial tree since he was born. His father bought the tree from a toy shop in Sheffield just months after Douglas was born. The four-foot tree remains the centre point of the Hewitt family household during every festive season. Mr. Hewitt, of South Anston, South Yorkshire, said, "It reminds us of my childhood, our children's childhood and our grandchildren and great-grandchildren's after that. They all come and look at it and smile; it's become part of the furniture. If we didn't put that Christmas tree up, it wouldn't feel like Christmas." The tree was passed down to Mr. Hewitt when he married Mavis. Mrs. Hewitt said, "Year after year we have just carried on using that one. You have to be a bit more careful with it now, as it's _ ." Their daughter, June Murphy, also has fond memories of the Christmas tree. She said, "It was in my grandparents' home and then it was given to us. It looks a little thin now, as each time you get it out something else falls off. It's become a bit of a family joke. Each year someone has to comment 'not again!' But it's a Christmas tradition of getting the tree out that we all love. We'd all be sad to see it go, as I think it would be hard to find such a loved replacement." Mr. Hewitt said, "There were a lot more branches on it, and it's lost its feathers that were all along the edge. There were little candle holders on the ends and little legs on it, but unfortunately they've been lost over the years."
Question: Where did Douglas Hewitt get the Christmas tree?
Options: (A) He got it from his father. (B) He bought it from a toy shop. (C) He made it by himself. (D) He cut it down in a forest.

Example Input: Article: The fact that blind people can see things using parts of their bodies apart from their eyes may help us to understand our feelings about color.If they can sense color differences, then perhaps we, too, are affected by color without knowing it.Salesmen have discovered by experience over a long period of time that sugar sells badly in green wrappings, that blue foods are considered not agreeable to the taste, and that cosmetics should never be packed in brown.These discoveries have grown into a whole subject of color psychology. Some of our preferences are clearly psychological.Dark blue is the color of the night sky and therefore connected with calm, while yellow is a day color connected with energy and encouragement.Experiments have shown that colors, partly because they are connected with psychology, also have a direct effect on people's mind.People in bright red surroundings show an increase in breathing speed, heartbeat and blood pressure.Red is exciting.Pure blue has exactly the opposite effect; it is a calming color.Being exciting, red was chosen as the signal for danger, but a closer study shows that a bright yellow can produce a more basic state of alarm, so fire engines in some advanced areas are now rushing around in bright yellow colors that stop buses, trucks and cars.
Question: The passage tells us that salesmen have _ .
Options: (A) tried colors on blind people (B) found out that colors affect sales (C) developed a special subject of color psychology (D) discovered the relationship between color and psychology
Example Output: B

Example Input: Article: Jamaican sprinter Usain Bolt plans to send a message to rival Tyson Gay by breaking the world 100m record in the London Grand Prix on Friday. Bolt, who won gold in the 100m,200m and 4*100m relay in reord times at the Beijing Olympics last year, is determined to use the Crystal Palace event to crush the morale of his main rival for gold at next month's World Athletics Championships in Berlin. The 22-year-old is slowly returning to peak form after posting 19.59 sec for the 200m in Lausanne earlier this month and clocking a time of 9.79 sec over 100m in cold, rainy conditions in Paris on Friday. Despite Bolt's impressive times, Gay still believes he has the beating of the Jamaican. But Bolt insists there is no one in the sport who scares him and he will prove the point in south London this weekend. Although Bolt believes he is only running at 85 percent at the moment while he recovers from injuries suffered in a recent car crash in Jamaica, he sees no reason why he can't break his world record 100m time of 9.69 seconds. However he won't get the chance to _ Gay in the 100m in London as the American is only running in the 200m, which Bolt is not competing in, so he will have to settle for underlining his own ability. "You never know what is possible. I will give my best either way. My friends are saying I'm bringing the rain wherever I go but we will see on Friday." While Bolt would love to make a big impact in London, he knows the main event is the World Championships. "The London Grand Prix will show me where I'm at and what I need to do. After, we can analyse what I need to do ahead of the World Championships."
Question: Which of the following is true?
Options: (A) Jamaican sprinter Usain Bolt broke the world 100m record in the London Grand Prix on Friday. (B) Bolt will not compete in the 200m in London because of Gay's impressive times. (C) Bolt won 3 gold medals at the Beijing Olympic Games at the age of 22. (D) Bolt suffered a car crash in London recently.
