Problem: Extract the answer to the question from the following context. Question: How do the trials occur? Context: In the United States, new pharmaceutical products must be approved by the Food and Drug Administration (FDA) as being both safe and effective. This process generally involves submission of an Investigational New Drug filing with sufficient pre-clinical data to support proceeding with human trials. Following IND approval, three phases of progressively larger human clinical trials may be conducted. Phase I generally studies toxicity using healthy volunteers. Phase II can include pharmacokinetics and dosing in patients, and Phase III is a very large study of efficacy in the intended patient population. Following the successful completion of phase III testing, a New Drug Application is submitted to the FDA. The FDA review the data and if the product is seen as having a positive benefit-risk assessment, approval to market the product in the US is granted.

Problem: Given the question: Extract the answer to the question from the following context. Question: What happened before the civil war, the Battle of Ankara or Mehmed I emerging as the sultan? Context: With the extension of Turkish dominion into the Balkans, the strategic conquest of Constantinople became a crucial objective. The empire had managed to control nearly all former Byzantine lands surrounding the city, but in 1402 the Byzantines were temporarily relieved when the Turco-Mongol leader Timur, founder of the Timurid Empire, invaded Anatolia from the east. In the Battle of Ankara in 1402, Timur defeated the Ottoman forces and took Sultan Bayezid I as a prisoner, throwing the empire into disorder. The ensuing civil war lasted from 1402 to 1413 as Bayezid's sons fought over succession. It ended when Mehmed I emerged as the sultan and restored Ottoman power, bringing an end to the Interregnum, also known as the Fetret Devri.

input question: Extract the answer to the question from the following context. Question: Who else was affected by the constitutional amendment besides the Soviets? Context: On October 25, 1989, the Supreme Soviet voted to eliminate special seats for the Communist Party and other official organizations in national and local elections, responding to sharp popular criticism that such reserved slots were undemocratic. After vigorous debate, the 542-member Supreme Soviet passed the measure 254-85 (with 36 abstentions). The decision required a constitutional amendment, ratified by the full congress, which met December 12–25. It also passed measures that would allow direct elections for presidents of each of the 15 constituent republics. Gorbachev strongly opposed such a move during debate but was defeated.???

Context: Francis Marcus of the International Federation of the Red Cross praised the Chinese rescue effort as "swift and very efficient" in Beijing on Tuesday. But he added the scale of the disaster was such that "we can't expect that the government can do everything and handle every aspect of the needs".

Q: Extract the answer to the question from the following context. Question: What was the aftermath? Context: In June 1963, Rev. Martin Luther King, Jr. gave a major speech in Detroit that foreshadowed his "I Have a Dream" speech in Washington, D.C. two months later. While the African-American Civil Rights Movement gained significant federal civil rights laws in 1964 and 1965, longstanding inequities resulted in confrontations between the police and inner city black youth wanting change. Longstanding tensions in Detroit culminated in the Twelfth Street riot in July 1967. Governor George W. Romney ordered the Michigan National Guard into Detroit, and President Johnson sent in U.S. Army troops. The result was 43 dead, 467 injured, over 7,200 arrests, and more than 2,000 buildings destroyed, mostly in black residential and business areas. Thousands of small businesses closed permanently or relocated to safer neighborhoods. The affected district lay in ruins for decades. It was the most costly riot in the United States.
