[EX Q]: 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
[EX A]: How long had the Taff Vale Railway been in existence the year it was extended to Cymmer?

[EX Q]: Passage: Jasanoff's 2017 book, The Dawn Watch: Joseph Conrad in a Global World, published by Penguin Press and in the UK by William Collins centers on the life and times of novelist Joseph Conrad. The Times lauded the book as the "Conrad for our time," and The Spectator called her an "enviably gifted writer...her historian's eye can untie knots that might baffle the pure critic," noting that she "steers us securely and stylishly through those latitudes where Conrad witnessed the future scupper the past." In the judgment of the Financial Times: "This is an unobtrusively skilful, subtle, clear-eyed book, beautifully narrated," while the Literary Review observes: "Written with a novelist's flair for vivid detail and a scholar's attention to texts, The Dawn Watch is by any standard a major contribution to our understanding of Conrad and his time." Reviewing the book in The Guardian, Patrick French began: "The Dawn Watch will win prizes, and if it doesn't, there is something wrong with the prizes." In The Hindu, Sudipta Datta wrote that Jasanoff's approach to Conrad makes for a "remarkable retelling of Joseph Conrad's life and work and its resonance with the present dysfunctional world." In The Guardian, William Dalrymple named the book to his list of best holiday reads of 2017. According to the Wall Street Journal's reviewer, "'The Dawn Watch' is the most vivid and suggestive biography of Conrad ever written." In The New York Times, Ngugi wa Thiong'O applauded the book as "masterful." Thiong'O wrote that Jasanoff succeeded where "An Image of Africa: Racism in Joseph Conrad's Heart of Darkness," Chinua Achebe's classic Conrad essay, had failed, specifically in bringing into clear relief "Conrad's ability to capture the hypocrisy of the 'civilizing mission' and the material interests that drove capitalist empires, crushing the human spirit." "'The Dawn Watch,' Thiong'O wrote, "will become a creative companion to all students of his work. It has made me want to re-establish connections with the Conrad whose written sentences once inspired in me the same joy as a musical phrase."
 Link Information: The Guardian is a British daily newspaper. It was founded in 1821  Answer: UK
[EX A]: In what country is the publication based that Patrick French writes for?

[EX Q]: Passage: Tomić belonged to the first class of six Serbian pilots trained in France in 1912. In August 1914, he participated in the first aerial dogfight of the war, when he exchanged gunfire with an Austro-Hungarian plane over western Serbia. In the winter of 1915, during the Serbian Army's retreat across Albania to the Greek island of Corfu, he evacuated General Petar Bojović from Scutari by plane, delivered mail by air and transported the Serbian Government's gold and hard currency reserves from Niš to keep them from falling into enemy hands. Following the occupation of Serbia by the Central Powers, Tomić went to France and flew over the Western Front, where he had one confirmed kill. He returned to the Balkans in late 1916, conducted combat missions over Bulgarian-occupied Macedonia and shot down one enemy plane. Tomić continued flying after the war and became head of the Royal Yugoslav Air Force's pursuit squadron in Novi Sad. During World War II, he was captured by the Germans and detained as a prisoner of war. Tomić left Yugoslavia following the war and settled in the United States with his wife. He died in Chicago in 1962.
