In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.

Example Input: Article: Once upon a time the colors of the world started to quarrel. Green said, "Clearly I am the most important. I am the sign of life and hope. I was chosen for grass, trees and leaves. Look over the countryside and you will see that I am in the majority." Blue interrupted, "You only think about the earth, but consider the sky and the sea. It is the water that is the basis of life." Yellow chuckled . "The sun is yellow, as well as the moon and the stars. Every time you look at a sunflower, the whole world starts to smile." Red could bear it no longer. "I am the ruler of all of you. I am blood-life's blood! I am the color of danger and bravery. I bring fire into the blood. I am the color of passion and love." Purple stood at his full height. "I am the color of royalty and power. I am the sign of authority and wisdom. People do not question me! They listen and obey." Finally Indigo spoke with determination, "Think of me and I am the color of silence. I represent thought and reflection. You need me for balance and contrast , for prayer and inner peace." The colors went on boasting , each showing off his or her own advantages. Suddenlythere came a flash of bright lightening. Thunder rolled and boomed. Rain started to pour down. The colors were scared to death. In the midst of the quarrelling, rain began to speak, "You foolish colors. Don't you know that you were each made for a special purpose, unique and different? Join hands with one another and come to me." Doing as they were told, the colors united and joined hands. From then on, when it rains, colors will stretch across the sky in a great bow of color. Whenever a rainbow appears in the sky, let us remember to appreciate one another.

Asnwer: C
Example Output: Yes

Example Input: Article: Charlie Bell became chief executive of McDonald's in April. Within a month doctors told him that he had color1ectal cancer. After stock market hours on November 22nd, the fast-food firm said he had resigned; it would need a third boss in under a year. Yet when the market opened, its share price barely dipped then edged higher. After all, McDonald's had, again, shown how to act swiftly and decisively in appointing a new boss. Mr. Bell himself got the top job when Jim Cantalupo died of a heart attack hours before he was due to address a convention of McDonald's franchisees . Mr. Cantalupo was a McDonald's veteran brought out of retirement in January 2003 to help remodel the firm after sales began falling because of dirty restaurants, indifferent service and growing concern about junk food. He devised a recovery plan, backed by massive marketing, and promoted Mr. Bell to chief operating officer. When Mr. Cantalupo died, a rapidly convened board confirmed Mr. Bell, a 44-year-old Australian already widely seen as his heir apparent, in the top job. The convention got its promised chief executive's address, from the firm's first non-American leader. Yet within weeks executives had to think about what to do if Mr. Bell became too ill to continue. Perhaps Mr. Bell had the same thing on his mind: he usually introduced Jim Skinner, the 60-year-old vice-chairman, to visitors as the "steady hand at the wheel". Now Mr. Skinner, an expert on the firm's overseas operations, becomes chief executive, and Mike Roberts, head of its American operations, joins the board as chief operating officer. Is Mr. Roberts now the new heir apparent? Maybe. McDonald's has brought in supposedly healthier choices such as salads and toasted sandwiches worldwide and, instead of relying for most of its growth on opening new restaurants, has turned to upgrading its 31,000 existing ones. America has done best at this; under Mr. Roberts, like-for-like sales there were up by 7. 5% in October on a year earlier. The new team's task is to keep the revitalization plan on course, especially overseas, where some American brands are said to face political hostility from consumers. This is a big challenge. Is an in-house succession(, ) the best way to tackle it? Mr. Skinner and Mr. Roberts are both company veterans, having joined in the 1970s. Some recent academic studies find that the planned succession of a new boss from within, such as Mr. Bell and now (arguably) Mr. Roberts, produces better results than looking hastily, or outside, for one. McDonald's smooth handling of its serial misfortunes at the top certainly seems to prove the point. Even so, everyone at McDonald's must be hoping that it will be a long time before the firm faces yet another such emergency.
Question: The main reason for the constant change at the top of McDonald is _ .
Options: (A) the constant change of its share price (B) the board's failure to reach an agreement (C) the falling sales (D) the physical problems of the chief executives
Asnwer: B
Example Output: No

Example Input: Article: The dirt road made our car jump as we traveled to the Millennium Village in Sauri, Kenya. We passed the market where women sat on the dusty ground selling bananas. Little kids were wrapped in cloth on their mothers' backs, or running around in bare feet and torn clothing. When we reached the village, we walked to the Bar Sauri Primary School to meet the people. Welcoming music and singing had almost everyone dancing. We joined the dancing and clapped along to the joyful, lively music. The year was 2004, the first time I had ever been to Sauri. The Millennium Village project was created to help reach the Millennium Development Goals, which were set by the United Nations in 2000. The plan is to get people out of poverty, assure them of access to health care and help them stabilize the economy and quality of life in their communities. The goals are supposed to be met by 2015; some other targets are set for 2025. But our first sight of Sauri showed us there was plenty of work to do. On that day in 2004, we followed the village leaders into Yala Sub-District Hospital. It wasn't in good shape. The rooms were packed with patients who probably wouldn't receive treatment, either because the hospital did not have it or the patients could not afford it. There was no running water or electricity in the hospital. It is hard for me to see people sick with preventable diseases who are near death when they shouldn't have to be. I just get scared and sad. Malaria is one disease, common in Africa, which is preventable and treatable. Mosquitoes carry malaria, and infect people by biting them. Kids can die from it easily, and adults get very sick. Mosquitoes that carry malaria come at night. A mosquito net, treated with chemicals that last for five years, keeps malarial mosquitoes away from sleeping people. Each net costs $5. There are some cheap medicines to get rid of malaria too. The solutions are simple, yet 20,000 kids die from the disease each day. So sad, and so illogical. Mosquito nets could save millions of lives. We walked over to see the farmers. Their crops started to die because they could not afford the necessary fertilizer and irrigation. Time and again, a family will plant seeds only to have an outcome of poor crops because of lack of fertilizer and water. Each year, the farmers worry: Will they harvest enough food to feed the whole family? Will their kids go hungry and become sick? Many kids in Sauri didn't attend school because their parents couldn't afford school fees. Some kids are needed to help with housework, such as fetching water and wood. In 2004, the schools had _ supplies like books paper and pencils, but the students wanted to learn. They all worked hard with the few supplies they had. It was hard for them to concentrate, though, as there's no midday meal. Great changes have taken place in these years. Today, Yala Sub-District Hospital has medicine, free of charge. Water is connected to the hospital, which also has a generator for electricity. There are no school fees, and the school now serves midday meals for the students. The attendance rate is way up. All this is encouraging supporters of the Millennium Villages project. There are many solutions to the problems that keep people poor. What it will really take is for the world to work together to change poor areas forever. When my kids are my age, I want this kind of poverty to be a thing of history. It will not be an easy task. But Sauri's progress shows us all that winning the fight against poverty is achievable in our lifetime.
