TASK DEFINITION: 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.
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: When was the city the yeshiva fled from founded? Passage:When the Bolsheviks revolted, the yeshiva was forced to flee from Lithuania to Kletsk, Poland. During his three years in Kletsk, Yechiel Michel attended the famed Talmudic lectures of Rabbi Meltzer and his son-in-law, Rabbi Aharon Kotler. Then he transferred to the Mir yeshiva, where he became a leading student of Rabbi Yeruchom Lebovitz and learned together with Rabbi Yechiel Michel Schlesinger, future rosh yeshiva of Yeshivas Kol Torah in Jerusalem, and Rabbi Yonah Karpilow of Minsk, who was killed in the Holocaust and whose Yonas Eilem was published posthumously. At this time, Rabbi Chaim Shmuelevitz and Rabbi Aryeh Leib Malin also studied in the Mir yeshiva. Despite being surrounding by such luminaries in Torah, R' Yechiel Michel was nonetheless thought of as "the genius of the yeshiva".


SOLUTION: When the Bolsheviks revolted, the yeshiva was forced to flee from Lithuania to Kletsk, Poland

PROBLEM: Question: What city is the place where Bossart graduated from? Passage:Karel Bossart was born on February 9, 1904 in Antwerp, Belgium. He graduated in Mining Engineering at the Université libre de Bruxelles in 1924. After winning a scholarship—under the Belgian American Education Foundation—to M.I.T. to study aeronautical engineering he remained in the US working for various aircraft companies. In 1945 he was chief of structures at Convair and proposed to the United States Air Force that a missile could be developed with a range of 8000 km. The Air Force was skeptical of Bossart's proposal, partly wishing to preserve the priority of Strategic Bombers, but granted him a limited contract to develop a prototype. Bossart's major innovation was the use of a monocoque design in which structural support was maintained by pressure within the inelastic fuel tanks. After a series of tests in 1947 the Air Force lost interest and Bossart was instructed to abandon the research, but by 1951 the escalation of the Cold War enabled Bossart to revive the project that became known as 'Atlas'. In 1955 the CIA reported that Soviet Russia had made swift progress on its own ICBM programme and Atlas became a crash project of the highest national importance. Bossart used this opportunity to advance work with high energy cryogenic fuels that resulted in the Centaur upper stage.


SOLUTION:
He graduated in Mining Engineering at the Université libre de Bruxelles in 1924
