In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

Example Input: Question: Which of the empires that succeeded the Achaemenid Empire had the smallest number of people? Passage:Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 7000 BC. The south-western and western part of the Iranian Plateau participated in the traditional Ancient Near East with Elam, from the Early Bronze Age, and later with various other peoples, such as the Kassites, Mannaeans, and Gutians. Georg Wilhelm Friedrich Hegel calls the Persians the "first Historical People". The Medes unified Iran as a nation and empire in 625 BC. The Achaemenid Empire (550330 BC), founded by Cyrus the Great, was the first true global superpower state and it ruled from the Balkans to North Africa and also Central Asia, spanning three continents, from their seat of power in Persis (Persepolis). It was the largest empire yet seen and the first world empire. The Achaemenid Empire was the only civilization in all of history to connect over 40% of the global population, accounting for approximately 49.4 million of the world's 112.4 million people in around 480 BC. They were succeeded by the Seleucid, Parthian, and Sasanian Empires, who successively governed Iran for almost 1,000 years and made Iran once again as a leading power in the world. Persia's arch-rival was the Roman Empire and its successor, the Byzantine Empire.

Example Output: They were succeeded by the Seleucid, Parthian, and Sasanian Empires, who successively governed Iran for almost 1,000 years and made Iran once again as a leading power in the world

Example Input: Question: How old was George II when his daughter was born? Passage:Charles Bertram was born in London in 1723. He was the son of an English silk dyer who was usually accounted to have emigrated to Copenhagen, Denmark, among the retinue of Princess Louisa, a daughter of GeorgeII, upon her marriage to Crown Prince Frederick of Denmark in 1743. (The prince became KingFrederickV three years later.) Other sources suggest the father immigrated earlier, in 1738. The father established himself as a hosier in 1744, and Charles seems to have benefited from the warm reception that Louisa and her retinue received from the Danes. On 5 July 1747, Charles petitioned the University of Copenhagen's Consortium for admission to study history, antiquities, philosophy, and mathematics. This seems to have been granted, although students were generally required to adhere to the Danish Church and Bertram remained Anglican. He became a friend and protege of Hans Gram, the royal librarian and a member of the privy council. On 23 March 1748, Bertram petitioned the king to be permitted to give public lectures on the English language and became a teacher of English in the Royal Marine Academy in Copenhagen. (Some accounts name him as a professor, rather than a tutor; if so, that status would have been granted some years later, as he was a new undergraduate in 1747.) His 1749 chrestomathy An Essay on the Excellency and Style of the English Tongue has been called the initiation of English-language printing in Denmark. A brother apparently died at sea in 1752, and at some point he married Cathrine Marie Gold.

Example Output: He was the son of an English silk dyer who was usually accounted to have emigrated to Copenhagen, Denmark, among the retinue of Princess Louisa, a daughter of GeorgeII, upon her marriage to Crown Prince Frederick of Denmark in 1743

Example Input: Question: Who did Nikolay Novosiltsev work for? Passage:In 1817, while still a student, Mickiewicz, Tomasz Zan and other friends had created a secret organization, the Philomaths. The group focused on self-education but had ties to a more radical, clearly pro-Polish-independence student group, the Filaret Association. An investigation of secret student organizations by Nikolay Novosiltsev, begun in early 1823, led to the arrests of a number of students and ex-student activists including Mickiewicz, who was taken into custody and imprisoned at Vilnius' Basilian monastery in late 1823 or early 1824 (sources disagree as to the date). After investigation into his political activities, specifically his membership in the Philomaths, in 1824 Mickiewicz was banished to central Russia. Within a few hours of receiving the decree on 22 October 1824, he penned a poem into an album belonging to Salomea Becu, the mother of Juliusz Sowacki. (In 1975 this poem was set to music in Polish and Russian by Soviet composer David Tukhmanov.) Mickiewicz crossed the border into Russia about 11 November 1824, arriving in Saint Petersburg later that month. He would spend most of the next five years in Saint Petersburg and Moscow, except for a notable 1824 to 1825 excursion to Odessa, then on to Crimea. That visit, from February to November 1825, inspired a notable collection of sonnets (some love sonnets, and a series known as Crimean Sonnets, published a year later).
