PROBLEM: Question: Which part of the body can lymph nodes be found in? 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.


SOLUTION: Diagnosis of MCC begins with a clinical examination of the skin and lymph nodes

PROBLEM: Question: Do more than 1,000 people live in either town that made up the final sled dog mail route? Passage:Charlie Biederman (November 11, 1918February 22, 1995) was a musher in Alaska best known for being the last surviving dog sled mail carrier in the United States. Charlie was born in Alaska as the son of Ed Biederman, a musher born in Bohemia who immigrated to the United States in 1874 and also delivered the mail via dog sled. The date of Charlie's birth is unclear, but contemporary U.S. Censuses indicate it likely was around 1919. Charlie had four siblings. Charlie was raised in Eagle, Alaska, but lived in an isolated cabin on the Yukon River for most of his life. From an early age, he assisted his father and brother in their winter deliveries of the mail to isolated cabins in central Alaska. In winter, the family lived in Eagle and ran the mail route between that town and Circle, another small settlement approximately downriver. In the summer, the family lived at their Yukon River cabin, harvesting fish for subsistence and boarding the dogs of fellow mushers. In 1938, the family were underbid for the main contract for mail delivery in the area by a bush pilot. Ed Biederman retired shortly afterward and died in 1945. The final dog sled mail route was replaced in 1963. That final route was from Gambell to Savoonga and was run by Chester Noongwook. In January 1995, he donated the mail-delivery sled he used to the National Postal Museum in Washington, D.C., where it hangs today. One month after making the delivery, he died on February 22, 1995.


SOLUTION: That final route was from Gambell to Savoonga and was run by Chester Noongwook

PROBLEM: Question: What is the seating capacity of the Gaddafi Stadium in Lahore? Passage:The England national cricket team, organised by Marylebone Cricket Club (MCC), toured India, Pakistan and Ceylon from October 1961 to February 1962. They played five Test matches against the India national cricket team, with India winning two matches and the other three being drawn; and three Tests against the Pakistan national cricket team, with England winning the first match and the other two drawn. The itinerary was unusual in that England began in Pakistan with three matches, including the first Test at the Gaddafi Stadium in Lahore, and then went on an extensive five-Test tour of India before crossing into East Pakistan (now Bangladesh), where they played their second Test against Pakistan at the Dacca Stadium in Dacca. For the third Test against Pakistan, they travelled to the National Stadium, Karachi before completing the tour in February with three games in Ceylon. Ceylon (now Sri Lanka was not a Test-qualified team at that time and played a single first-class match against MCC in Colombo which was won by MCC.
