Input: Consider Input: Passage: Egyptian President Anwar Sadat whose policies included opening Egypt to Western investment (infitah); transferring Egypt's allegiance from the Soviet Union to the United States; and making peace with Israel released Islamists from prison and welcomed home exiles in tacit exchange for political support in his struggle against leftists. His "encouraging of the emergence of the Islamist movement" was said to have been "imitated by many other Muslim leaders in the years that followed." This "gentlemen's agreement" between Sadat and Islamists broke down in 1975 but not before Islamists came to completely dominate university student unions. Sadat was later assassinated and a formidable insurgency was formed in Egypt in the 1990s. The French government has also been reported to have promoted Islamist preachers "in the hope of channeling Muslim energies into zones of piety and charity."

Output: Who is the President of Afghanistan?

Input: Consider Input: Passage: The Black Death is thought to have originated in the arid plains of Central Asia, where it then travelled along the Silk Road, reaching Crimea by 1343. From there, it was most likely carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships. Spreading throughout the Mediterranean and Europe, the Black Death is estimated to have killed 3060% of Europe's total population. In total, the plague reduced the world population from an estimated 450 million down to 350375 million in the 14th century. The world population as a whole did not recover to pre-plague levels until the 17th century. The plague recurred occasionally in Europe until the 19th century.
Output: In what year did the Black Death originate in Central Asia?
