Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: Was the U.S. Congressman from Suffolk County older than the candidate he opposed in the 2000 Senate race? Passage:Suffolk County had long been a Republican bastion in New York State. U.S. Congressman Rick Lazio, who opposed Hillary Clinton in the 2000 Senate race, was from Suffolk County. However, recent elections have turned the county more toward the Democrats. In 2003, Democrat Steve Levy was elected county executive, ending longtime Republican control. In 2001, Democrat Thomas Spota was elected District Attorney, and ran unopposed in 2005. Although Suffolk voters gave George H. W. Bush a victory here in 1992, the county voted for Bill Clinton in 1996 and continued the trend by giving Al Gore an 11-percent victory in the county in 2000. 2004 Democratic candidate John Kerry won by a much smaller margin of one percent, in 2008 Democratic candidate Barack Obama won by a slightly larger 4.4 percent margin, 52%-47%. In 2016, Republican candidate Donald Trump won Suffolk County by a 6.9 percent margin after absentees, marking the largest margin of victory for the Republicans since 1988. It was the only large county (over 200,000 voters) in New York State that Donald Trump won.

Example Input: Question: How long passed between the Potsdam Declaration and the San Francisco Peace Treaty signing? Passage:The Allied occupation of Japan at the end of World War II was led by General Douglas MacArthur, the Supreme Commander of the Allied Powers, with support from the British Commonwealth. Unlike in the occupation of Germany, the Soviet Union was allowed little to no influence over Japan. This foreign presence marks the only time in Japan's history that it has been occupied by a foreign power. At MacArthur's insistence, Emperor Hirohito remained on the imperial throne. The wartime cabinet was replaced with a cabinet acceptable to the Allies and committed to implementing the terms of the Potsdam Declaration, which among other things called for the country to become a parliamentary democracy. Under MacArthur's guidance, the Japanese government introduced sweeping social reforms and implemented economic reforms that recalled American "New Deal" priorities of the 1930s under President Roosevelt. The Japanese constitution was comprehensively overhauled and the Emperor's theoretically-vast powers, which for many centuries had been constrained by conventions that had evolved over time, became strictly limited by law. The occupation, codenamed Operation Blacklist, was ended by the San Francisco Peace Treaty, signed on September 8, 1951, and effective from April 28, 1952, after which Japan's sovereigntywith the exception, until 1972, of the Ryukyu Islands was fully restored.

Example Input: Question: Where Shah Nawaz Bhutto and his third son born in the same city? Passage:Shah Nawaz Bhutto, a direct descendant of Muhammad Khan, came to prominence during the British Raj as a dewan of the princely state of Junagadh in south-western Gujarat in India. During the Partition of India in 1947, the Muslim Nawab of Junagarh wanted to accede his state to the newly created Pakistan, but he faced rebellion by the population of Junagadh, majority of whom were Hindus. The Indian government thwarted Junagadh's accession to Pakistan, and the Bhuttos fled to Sindh in modern-day Pakistan. Shah Nawaz Bhutto moved to Larkana District in Sindh, where his land-ownership made him one of the wealthiest and most influential people in Sindh. Beginning the political dynasty, Shah Nawaz's third son Zulfikar Ali Bhutto (1928-1979) founded the Pakistan People's Party (PPP) in 1967 and served as President and Prime Minister. He married an Iranian-Kurdish woman named Nusrat Bhutto. His daughter, Benazir (1953-2007), also served as Prime Minister, while Benazir's husband, Asif Ali Zardari, later served as president from 2008 to 2013. The Bhuttos continue to dominate the leadership of the PPP. Benazir's son Bilawal Bhutto Zardari became co-chairperson in 2007.
