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: Treasure hunts have excited people's imagination for hundreds of years both in real life and in books such as Robert Louis Stevenson's Treasure Island. Kit Williams, a modern writer, had the idea of combining the real excitement of a treasure hunt with clues found in a book when he wrote a children's story, Masquerade, in 1979. The book was about a hare, and a month before it came out, Williams buried a gold hare in a park in Bedfordshire. The book contained a large number of clues to help readers find the hare, but Williams put in a lot of "red herrings", or false clues, to mislead _ . Ken Roberts, the man who found the hare, had been looking for it for nearly two years. Although he had been searching in the wrong area most of the time, he found it by logic, not by luck. His success came from the fact that he had gained an important clue at the start. He had realized that the words: "One of Six to Eight" under the first picture in the book connected the hare in some way to Katherine of Aragon, the first of Henry VIII's six wives. Even here, however, Williams had succeeded in misleading him. Ken knew that Katherine of Aragon had died at Kimbolton in Cambridgeshire in 1536 and thought that Williams had buried the hare there. He had been digging there for over a year before a new idea occurred to him. He found out that Kit Williams had spent his childhood near Ampthill, in Bedfordshire, and thought that he must have buried the hare in a place he knew well, but he still could not see the connection with Katherine of Aragon, until one day he came across two stone crosses in Ampthill Park and learnt that they had been built in her honor in 1773. Even then his search had not come to an end. It was only after he had spent several nights digging around the cross that he decided to write to Kit Williams to find out if he was wasting his time there. Williams encouraged him to continue, and on February 24th 1982, he found the treasure. It was worth L3000 in the beginning, but the excitement it had caused since its burial made it much more valuable.
Question: What is the subject discussed in the text?
Options: (A) An exciting historical event. (B) The importance of logical thinking. (C) The attraction of Masquerade. (D) A modern treasure hunt.
Asnwer: C
