Example Input: Question: How long did the king who was painted by Jan Matejko rule Poland? Passage:Modern history accepts this gateway as one of three constructed by Yaroslav the Wise. The golden gates were built in 1017-1024 (6545 by the Byzantine calendar) at about the same time the Saint Sophia Cathedral was erected. Mentions of an older construction, such as the one presented on a painting by Jan Matejko of king Bolesław I of Poland striking the Golden Gate with his sword during the intervention in the Kievan succession crisis in 1018, it is now regarded a legend. Originally named simply the Southern Gate, it was one of the three main entrances to the walled city, along with the Ladski and Zhydivski (Polish and Jewish) Gates. The last two have not survived. The stone fortifications stretched for only 3.5 km. The fortification of the Old Kyiv (Upper City) stretched from the Southern Gates down to what is now Independence Square and where the Lechitic Gate was located. From there, the moat followed what is now Kostyol Street, skirting St. Michael's Monastery and continuing along today's Zhytomyr Street toward the Jewish Gates (at ). From there, the fortification stretched what is now Yaroslaviv Val ("Yaroslav's Rampart") Street back to the Southern Gate.

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.
