Input: Read this: During the Second Sino-Japanese War, which led into World War II, much of Zhejiang was occupied by Japan and placed under the control of the Japanese puppet state known as the Reorganized National Government of China. Following the Doolittle Raid, most of the B-25 American crews that came down in China eventually made it to safety with the help of Chinese civilians and soldiers. The Chinese people who helped them, however, paid dearly for sheltering the Americans. The Imperial Japanese Army began the Zhejiang-Jiangxi Campaign to intimidate the Chinese out of helping downed American airmen. The Japanese killed an estimated 250,000 civilians while searching for Doolittle's men.
Question: How many estimated civilians were rescued by the Japanese searching for Doolittle's men?

Output: unanswerable

Input: Read this: It is very rare for top clubs to miss the competition, although it can happen in exceptional circumstances. Defending holders Manchester United did not enter the 19992000 FA Cup, as they were already in the inaugural Club World Championship, with the club stating that entering both tournaments would overload their fixture schedule and make it more difficult to defend their Champions League and Premiership titles. The club claimed that they did not want to devalue the FA Cup by fielding a weaker side. The move benefited United as they received a two-week break and won the 19992000 league title by an 18-point margin, although they did not progress past the group stage of the Club World Championship. The withdrawal from the FA Cup, however, drew considerable criticism as this weakened the tournament's prestige and Sir Alex Ferguson later admitted his regret regarding their handling of the situation.
Question: What FA Cup season did Manchester United enter?

Output:
unanswerable
