In this task, you're given a passage, further information available on a particular linked term from the statement, and an answer term. Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

Example Input: Passage: In 1809, Walter Coffin sunk the first coal pit in the Rhondda, further up the valley in Dinas, but a lack of a transportation network greatly affected the profitability of coal mining as an industry in the region. Coffin tackled this problem by constructing a one-mile tramline which connected his mines in Dinas to a tramline built by Dr. Richard Griffiths at Denia (Pontypridd), which linked to a private canal that joined onto the Glamorganshire Canal at Treforest. Coffins tramline followed the southern bank of the River Rhondda and ran through Porth. The existence of the tramline made the development of the Porth and Cymmer region far more attractive, and by the middle of the 19th century there was an impetus to expand coal mining in the area. In 1841 Richard Lewis joined Coffin in trying to exploit the region with his level built at Cymmer. This resulted in the construction of around fifty miners' cottages, several of which were located in Porth. In 1844 Lewis Edwards of Newport and George Gethin of Penygraig opened a small level at Nyth-bran on the eastern borders of Porth, the villages' first coal mine. This was followed in 1845 by the sinking of the Porth Colliery by David James of Merthyr, the success of which saw him build the Llwyncelyn Colliery in 1951, also in Porth. By 1850 the Taff Vale Railway had been extended to Cymmer replacing the tramline, allowing direct access between the lower Rhondda and the ports of Cardiff.
 Link Information: It was opened in stages in 1840 and 1841. Answer: 10
Example Output: How long had the Taff Vale Railway been in existence the year it was extended to Cymmer?

Example Input: Passage: Jablonski was born in the village of Nassenhuben, near Danzig (Gdańsk). His father, Peter Figulus, was a minister of Unity of the Brethren (; – also known as "Bohemian Brethren"); the son preferred the Bohemian surname Jablonski (Jablonský) which was based on his father's birthplace – Jablonné nad Orlicí. He was the younger brother of Johann Theodor Jablonski. His maternal grandfather, Johann Amos Comenius (d. 1670), was the last bishop of the Unity. Having studied at Frankfurt (Oder) and at Oxford, Jablonski entered upon his career as a preacher at Magdeburg in 1683, and then from 1686 to 1691 he was the head of the Brethren college at Polish Leszno (), a position which had been filled by his grandfather. Consecrated a bishop of the Unity for the churches in Poland, he was encouraged by the Elector Friedrich Wilhelm I of Brandenburg, King in Prussia, to secure the Apostolic Succession to the Renewed Unity of Brethren, the Moravian Church, and consecrated David Nitschmann bishop in Berlin in 1735.

Example Output: What  degree did Daniel Ernst Jablonski earn from his time at two colleges?

Example Input: Passage: Haschka was born and died in Vienna. In his youth, he was a member of the Society of Jesus. On the suppression of the Society (1773) he devoted himself, in secular life, to poetry, this was now to become his vocation and his means of livehood. His pupil, the wealthy Johann Baptist von Alxinger, an imitator of Christoph Martin Wieland, came to his assistance. Haschka also found aid in the home of poet Karoline Pichler. Having left the Jesuits, under the influence of Josephinism, he became a freemason and wrote odes against the papacy during the presence of Pius VI in Vienna, as well as against the religious orders. He returned to Catholicism after the death of Joseph II, Holy Roman Emperor, and was selected to compose a national anthem, which was first sung on 12 February 1797, at the celebration of Francis II's birthday. Haschka was given a position as assistant in the library of the University of Vienna and was made instructor in aesthetics in the newly founded Theresianum. He retired in 1824.
