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: D

Article: It was a sunny holiday Monday. Olivier Ferrante was cooking sausages on the barbecue and entertaining friends in his garden north of Paris when the phone rang. The call came from the BEA, France's air accidents investigation bureau , where the 38-year-old former football player and driver was an investigator. The news was grim. "An Airbus is missing over the Atlantic: we need you." As a safety investigator,Ferrante and his teams had participated, directly and indirectly,in the recovery of crashed planes from the Red Sea, the Black Sea,and every ocean. But this investigation would be his toughest ever: the plane had disappeared without a witness, or a trace on radar . At least eight ships and a dozen military aircraft gathered on the plane's last known position, about halfway between Brazil and Western Africa. After six days the aircraft's tail fin and 50 bodies were spotted on the surface and the first burning questions were answered. The plane wreckage and passenger injuries indicated the doomed Airbus was unbroken when it hit the water. It was not exploded apart by a bomb or lightning, now broken up by violent weather. Strangely, no mayday message had been sent by its pilots. Ferrante worked energetically with his team:collecting offers of help from around the world, consulting navy ministries and research organizations in France and elsewhere, and contracting suitable ships and high-tech equipment. He would not return home for another 29 days. His team used the Autonomous Underwater Vehicle(AUV) operated around the clock, searching about 400 square kilometers a day. But the race against time was lost and no signals were heard and no more wreckage was found. Day after day, the screen remained bare except for objects that turned out to be stones or garbage from ships. Stressed by media attention and painful meetings with victims' s,Ferrante went jogging one day to clear his head. Then he had an idea. He decided to look at what had happened to nine other planes that crashed after something abruptly went wrong while flying at high altitude. He found that none had traveled more than 30 km before hitting the sea; most covered less than half that distance. AUV operations continued but now they focused on a 30 km circle around the plane's last known position. On the ninth day of the new-strategy searching, after searching for 22 months, their hard work paid off finally. The first thing they saw was a woman's handbag. Next,they saw bits of twisted aircraft parts and a panel with "AF" painted on it. Without a doubt,this was the missing Aribus,lying 11 km northeast of its last known position, but nobody felt much like cheering the discovery. "The screen also exposed well-preserved human bodies,and for some of us they were hard to look at," says Ferrante.
