Task: Question Generation
Input (English):  During his meeting in Dakar with the head of the Reunited Nations African Development Project, Dr. Homer Crawford resigns his post as leader of the Sahara Division team to become El Hassan, the liberator and would-be tyrant of North Africa. Threatened with arrest, Crawford and his followers hide in the Sahara erg. They intercept news that the Arab Union has occupied Tamanrasset, ostensibly to protect the region against El Hassan rioters. Crawford decides to recapture Tamanrasset and use its communications system to proclaim his regime. To do so, he sends his followers to organize troops from nearby regions: the Teda from the east, the Chaambra from the north, the Sudanese from the south, and the Nemadi, Moors, and Rifs from the West. Crawford, Isobel Cunningham, and Cliff Jackson will establish the movement's headquarters in Tuareg country. They are all to rendezvous at Tamanrasset in two weeks.
Crawford wins the loyalty of the Tuareg warriors by offering to make them the core of El Hassan s Desert Legion during wartime and his policemen and rangers during peacetime. Rex Donaldson, ex-field expert for the African Department of the British Commonwealth, arrives to join Crawford's organization, bringing fieldworkers Jack and Jimmy Peters and David Moroka with him. As they are being briefed, David thwarts an assassination attempt against Crawford, killing the assassin. Crawford then sends Rex to recruit troops in Senegal and Mali. Now guarded by fifteen Tuareg warriors, Crawford s group travels the country to rally up forces for the upcoming Tamanrasset battle. They capture Dr. Warren Harding Smythe's American Medical Relief team and force them to join the group. As Crawford's team puts together El Hassan s government, Jack proposes that they make Esperanto the common language of the movement. Kenny Ballalou arrives from the West with news: several Reunited Nations development teams have joined El Hassan, so he now controls a large portion of North Africa. As El Hassan's influence grows, so does his camp, which fills with reporters and foreign diplomats anxious to meet him.
Crawford's group decides to use guerrilla tactics to disable the mechanized army of the Arab Union. They are reprieved from air attack temporarily when the Reunited Nations announces retaliation against any power that uses air combat. Meanwhile, David, who in reality is a Party member of the Soviet Complex, radios his superiors, revealing that he engineered the attempted assassination of Crawford to earn his trust. C.I.A. agent Fred Ostrander arrives at the camp to remind Crawford of his allegiance to the United States and the West, but Crawford responds that he is an African looking for African solutions to African problems. When Ostrander challenges Crawford to explain why he is the man to lead North Africa, Crawford responds that he was thrust into the job. He then expresses deep regret that becoming El Hassan led him to kill his best friend, Abe, who wanted him to swear allegiance to the Soviet Complex. Crawford's confession disarms David, whose spying has been fueled by a desire to revenge Abe.
Isobel surprises David as he is reporting to his superiors, but when confronted by the team, David claims he has resigned from the Party and is now an El Hassan man. He also informs them that the Arab Union is planning to parachute troopers into various points of the Sahara. Ostrander, who has decided to join El Hassan's team as well, earns them some time by telling the commander of the Arab legion that the United States will send its own air force to aid El Hassan if the paratroopers are deployed. As everyone arms for battle, David and Ostrander have one last conversation, in which they insist that their long-term socioeconomical views have not changed, but that both believe African union takes precedence for the moment. They wish each other well during the coming fight.
During the aftermath of the successful recapture of Tamanrasset, Crawford finds that Jack, David, and Ostrander are dead and that Kenny has been seriously hurt. He then receives good news and bad news: foreign countries and organizations have begun to recognize El Hassan as the legal head of North Africa; Elmer Allen has been captured by one of Crawford's enemies, the leader of the Ouled Touameur clan, Abd-el-Kader. To make matters worse, Abd-el-Kader now claims to be the reincarnation of the Mahdi, the holiest prophet since Mohammed, so that he can call on a holy war against El Hassan.
Output (English): Why does Crawford hide in the Sahara erg?
