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.

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.

Question: Who commanded the 13th Hussars when Anstruther-Gray joined as a second lieutenant? Passage:He joined the Militia's Fife Artillery as a Sub-Lieutenant (Supernumerary) on 16 December 1876. He served for four years until he joined the 13th Hussars as a second lieutenant in 1880, served in India and Afghanistan in 1880-1881 and was promoted to lieutenant on 1 July 1881, before transferring to the Royal Horse Guards in 1885. He was Aide-de-Camp to the Earl of Kintore, Governor of South Australia, from 1889-1891, was promoted to captain on 30 December 1893, and to major on 1 May 1897. He served in South Africa from 1901-1902 where he was commandant of the district of Knysna in 1901, and Inspector of Concentration Camps in Transvaal in 1902. Following the end of the war in June 1902, he returned to the United Kingdom in the SS Dunottar Castle, which arrived at Southampton in July 1902.

Question: Which of the Beatles who used the Gibson J-160E were older when they died? Passage:Both John Lennon and George Harrison used the Gibson J-160E, an acoustic guitar with an electric pickup at the base of the fretboard. The resonant character of the full acoustic body, combined with the electric pickup, meant that this guitar was susceptible to feedback, employed to great effect on the intro to "I Feel Fine". Lennon also used a Framus Hootenanny twelve-string acoustic, which can be seen in the movie Help! and heard on the title song and "You've Got to Hide Your Love Away". This twelve-string guitar accounted for audibly richer rhythm guitar parts on songs like these, in comparison to the six-string Gibsons. After Sgt. Pepper's Lonely Hearts Club Band, Lennon moved on to a Martin D-28 from C. F. Martin & Company (alternating between the J-160E and the D-28 for The White Album) while Harrison upgraded to a Gibson J-200 Jumbo (which Lennon used on "Two of Us" and other acoustic tracks on Let It Be).
