Example Input: Paris, France (CNN) -- Hundreds of French workers, angry about proposed layoffs at a Caterpillar factory, were holding executives of the company hostage Tuesday, a spokesman for the workers said. Caterpillar's French staff say they are angry about a lack of negotiations over layoffs. It is at least the third time this month that French workers threatened with cutbacks have blockaded managers in their offices to demand negotiations. Executives were released unharmed in both previous situations. The latest incident started Tuesday morning at the office of the construction equipment company in the southeastern city of Grenoble. The workers were angry that Caterpillar had proposed cutting more than 700 jobs and would not negotiate, said Nicolas Benoit, a spokesman for the workers' union. They did not want to harm the Caterpillar executives, Benoit told CNN. One hostage was released Tuesday evening leaving workers with four captives inside the Caterpillar building. The released man was a human resources director identified only as Mr. Petit, because he has heart problems, union representative Bernard Patrick told CNN. Petit had a heart attack a few weeks ago, Patrick said. The four others still being held are Nicolas Polutnik, the head of operations; two other executives; and Petit's personal assistant, he said. About 500 employees were also outside the building protesting. <sep>When was Mr. Petit released?<sep>Tuesday morning
Example Output: No

Example Input: Alexander II (Russian: Aleksandr II Nikolaevich, tr. Aleksandr II Nikolaevich; IPA: [aljI'ksandr fta'roj njIka'lajIvjItc]; 29 April [O.S. 17 April] 1818 in Moscow - 13 March [O.S. 1 March] 1881 in Saint Petersburg) was the Emperor of Russia from 2 March 1855 until his assassination in 1881. He was also the King of Poland and the Grand Duke of Finland. Alexander was the most successful Russian reformer since Peter the Great. His most important achievement was the emancipation of serfs in 1861, for which he became known as Alexander the Liberator (Russian: Aleksandr Osvoboditel', tr. Aleksandr Osvoboditel; IPA: [aljI'ksandr asv@ba'djitjIlj]). The tsar was responsible for numerous other reforms including reorganizing the judicial system, setting up elected local judges, abolishing capital punishment, promoting local self-government through the zemstvo system, imposing universal military service, ending some of the privileges of the nobility, and promoting the universities. Despite these reforms, during his reign, his brutal secret police, known as the Third Section, sent thousands of dissidents into exile in Siberia. In foreign policy, Alexander sold Alaska to the United States in 1867, fearing the remote colony would fall into British hands if there was another war. He sought peace, moved away from bellicose France when Napoleon III fell in 1871, and in 1872 joined with Germany and Austria in the League of the Three Emperors that stabilized the European situation. Despite his otherwise pacifistic foreign policy, he fought a brief war with Turkey in 1877-78, pursued further expansion into Siberia and the Caucasus, and conquered Turkestan. Although disappointed by the results of the Congress of Berlin in 1878, Alexander abided by that agreement. Among his greatest domestic challenges was an uprising in Poland in 1863, to which he responded by stripping that land of its separate Constitution and incorporating it directly into Russia. Alexander was proposing additional parliamentary reforms to counter the rise of nascent revolutionary and anarchistic movements when he was assassinated in 1881. <sep>Why is Alexander II called Aleksandr Osvoboditel?<sep>Because he captured Poland
Example Output: No

Example Input: The second major point on which the principals had agreed on March 10 was the need to crack down on terrorist organizations and curtail their fund-raising. The embassy bombings of 1998 had focused attention on al Qaeda's finances. One result had been the creation of an NSC-led interagency committee on terrorist financing. On its recommendation, the President had designated  Bin Laden and al Qaeda as subject to sanctions under the International Emergency Economic Powers Act. This gave theTreasury Department's Office of Foreign Assets Control (OFAC) the ability to search for and freeze any  Bin Laden or al Qaeda assets that reached the U.S. financial system. But since OFAC had little information to go on, few funds were frozen. In July 1999, the President applied the same designation to the Taliban for harboring  Bin Laden. Here, OFAC had more success. It blocked more than $34 million in Taliban assets held in U.S. banks. Another $215 million in gold and $2 million in demand deposits, all belonging to the Afghan central bank and held by the Federal Reserve Bank of New York, were also frozen. After October 1999, when the State Department formally designated al Qaeda a "foreign terrorist organization," it became the duty of U.S. banks to block its transactions and seize its funds. Neither this designation nor UN sanctions had much additional practical effect; the sanctions were easily circumvented, and there were no multilateral mechanisms to ensure that other countries' financial systems were not used as conduits for terrorist funding. Attacking the funds of an institution, even the Taliban, was easier than finding and seizing the funds of a clandestine worldwide organization like al Qaeda. Although the CIA's  Bin Laden unit had originally been inspired by the idea of studying terrorist financial links, few personnel assigned to it had any experience in financial investigations. Any terrorist-financing intelligence appeared to have been collected collaterally, as a consequence of gathering other intelligence. This attitude may have stemmed in large part from the chief of this unit, who did not believe that simply following the money from point A to point B revealed much about the terrorists' plans and intentions. As a result, the CIA placed little emphasis on terrorist financing. Nevertheless, the CIA obtained a general understanding of how al Qaeda raised money. <sep>Why did the CIA place little emphasis on investigating terrorist funding?<sep>Because Taliban doesn't have much financial activities
