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.

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

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

Q: Passage: Diagnosis of MCC begins with a clinical examination of the skin and lymph nodes. Following, definitive diagnosis of Merkel cell carcinoma (MCC) requires examination of biopsy tissue to identify its histopathologic features. An ideal biopsy specimen is either a punch biopsy or a full-thickness incisional biopsy of the skin including full-thickness dermis and subcutaneous fat. On light microscopy, MCC shows basaloid tumor nests with neuroendocrine features ("salt and pepper" chromatin, scarce cytoplasm, and brisk mitotic activity). In addition to standard examination under light microscopy, immunohistochemistry (IHC) is also generally required to differentiate MCC from other morphologically similar tumors such as small cell lung cancer, the small cell variant of melanoma, various cutaneous leukemic/lymphoid neoplasms, and Ewing's sarcoma. Similarly, most experts recommend longitudinal imaging of the chest, typically a CT scan, to rule out that the possibility that the skin lesion is a skin metastasis of an underlying small cell carcinoma of the lung. Once an MCC diagnosis is made, a sentinel lymph node biopsy is recommended as a part of the staging work-up needed to determine prognosis and subsequent treatment options.
 Link Information: Lymph nodes are present throughout the body, are more concentrated near and within the trunk, and are divided in the study of anatomy into groups. There are about 450 lymph nodes in the adult. Some lymph nodes can be felt when enlarged (and occasionally when not), such as the axillary lymph nodes under the arm, the cervical lymph nodes of the head and neck and the inguinal lymph nodes near the groin crease. Most lymph nodes lie within the trunk adjacent to other major structures in the body - such as the paraaortic lymph nodes and the tracheobronchial lymph nodes.

There are no lymph nodes in the central nervous system, which is separated from the body by the blood-brain barrier.

 Answer: under the arm

A: Which part of the body can lymph nodes be found in?

Q: Passage: Kork fought in World War I on the Northwestern Front and the Western Front. In October 1914, he was awarded the Order of Saint Anna 3rd class with Swords. On 1 April 1915, he was awarded the Order of Saint Stanislaus 2nd class with Swords. Kork became an adjutant on the staff of the 3rd Siberian Army Corps and was promoted to Staff captain on 14 June. On 16 November, Kork received the Order of Saint Anna 4th class. At the same time he became an adjutant at the headquarters of the 8th Siberian Rifle Division. On 25 or 30 December he was transferred to the 10th Army headquarters. He also served with the 20th Army Corps and the Office of the Quartermaster General on the Staff of the Western Front. On 15 August 1916, he was promoted to Captain. In 1917, he graduated from the Observer-Pilot Military School. On 25 February, Kork became officer for Aircraft Orders on the Staff of the Western Front. He was promoted to lieutenant colonel. On 31 March, Kork was awarded the Order of Saint Anna 2nd class with Swords. Between August 1917 and February 1918 he was chairman of the Soldiers' Committee of the Western Front.
