In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: What was the document that made India an officially secular nation ratified? Passage:India's present syncretic culture is reflected in the fused Hindu-muslim spiritual connotations, forms, symbols, aesthetics, crafts and weaves, for example Kashmiri muslim carpet makers feature Durga in their patterns, muslim sculptors making idols of Durga, and Hindu craftsmen create the Muharram tazia. This religious syncretism is a fusion of Hindu cultural elements with Muslim religious elements. It is based on the vasudhaiva kutumbakam, unity in diversity, multi-communitarianism and ganga-jamuni tehzeeb, It is born out of centuries of interfaith exchange and accommodation among Indian origin religions (Hindu, Buddhist, Jain, Sikh) and foreign origin religions (Muslim and Christian) where communities preserve own cultural and religious identities while facilitating the shared celebration of festivals, customs and traditions. In this syncretic culture, the shared Indian national identity is separated from the personal religious identity, and the nation and common social good comes first above the personal religion. Despite the partition of India, and resulting creation of Pakistan based on the concept of separate islamic nation for domination of muslims, this composite multiculturalism is integral to the present society of India. India is officially a secular nation, a concept legalised in the constitution of India. Contrastingly, constitution of Pakistan has Islam as its state religion, teaching of quran and islamiyat is compulsary,Constitution of Pakistan: Constitution of Pakistan, 1973 – Article: 31 Islamic way of life, Article 31 No. 2, 1973, Retrieved 22 August 2018. only muslims can become Prime Minister or President of Pakistan and nonmuslims are not given equal rights, Ahmadia muslims having equal constitutional rights in India are legally persecuted in Pakistan and constitutionally banned from calling themselves Muslims.

Example Input: Question: Was Montana the quarterback during each of Walsh's Super Bowl wins? Passage:Walsh first developed what would become the West Coast offense when he was offensive coordinator of the Cincinnati Bengals, working under legendary head coach Paul Brown. However, Walsh truly perfected this strategy as the head coach of the San Francisco 49ers. His teams were led by quarterback Joe Montana. Montana, who was noted for his ability to remain calm under pressure, also possessed good mobility and an accurate passing arm. Another important player in the 49ers offense was Roger Craig, a swift, speedy running back who could also catch passes out of the backfield and was a good receiver. Walsh's 49ers teams also featured several All-Pro wide receivers, including Dwight Clark, John Taylor, and Jerry Rice. The 49ers were one of the NFL's powerhouses in the 1980s and 1990s, under the guidance of head coaches Bill Walsh (1979–1988) and George Seifert (1989–1996). Walsh won three Super Bowls in the 1981, 1984 and 1988 seasons. Seifert won two Super Bowls in 1989 and 1994. Montana, Walsh and Rice are in the Pro Football Hall of Fame, and so is Montana's successor, quarterback Steve Young. Like Montana, Young was a great running quarterback and a very efficient passer.

Example Input: Question: How many children does the candidate from Arkansas who won the state with ease in 1992 and 1996 have? Passage:For the better part of a century, Missouri has been reckoned as the nation's bellwether state. Prior to 2008, since 1904, Missouri had voted for the winner in every presidential election except in 1956 when the state narrowly voted for Democrat Adlai Stevenson of neighboring Illinois over incumbent Republican President Dwight D. Eisenhower. In recent years, however, it has gradually been trending Republican. Although Bill Clinton of neighboring Arkansas won the state with ease during both of his elections in 1992 and 1996, Al Gore and John Kerry considered the Show-Me State a lost cause and did not campaign much there. Although Barack Obama is from neighboring Illinois, at first he likewise put the state as a secondary concern in relation to other swing states such as Ohio and Virginia where he thought he had more of a chance. As his lead diminished in the summer months, he and McCain moved the campaign to more Democratic-friendly states, as McCain maintained a comfortable polling lead in Missouri. Similar hypothetical general match-up polls taken between McCain and Hillary Rodham Clinton, however, showed Clinton always leading in Missouri.
