[EX Q]: Passage: 'Robert D. Raiford (December 27, 1927 – November 17, 2017) was an American radio broadcaster and actor, best known for his political/social commentaries delivered during The John Boy and Billy Big Show, a morning radio program heard on stations throughout the American South. He was from Concord, North Carolina and majored in communication at the University of South Carolina. Raiford got his start in broadcasting in 1944 by calling play by play at baseball games. His first real radio job was at WEGO (AM) in Concord, North Carolina. Raiford has appeared in 28 movies, often portraying judge characters. He frequently closed his commentaries with the line "Who says that? I say that!", which also served as the title of a book containing excerpts from these segments. Early in his career, Raiford worked for WTOP radio and WTOP-TV, both CBS News affiliates in Washington, D.C.. His best-known work was a live radio broadcast on WTOP, a CBS Radio affiliate, covering the state funeral of President John F. Kennedy. He also worked at Charlotte radio station WBT. Raiford also hosted a show on WIST, which aired Charlotte's first telephone talk radio format. He later taught Communications at the University of North Carolina at Charlotte. From 1978 to 1986, Raiford was a news anchor and talk show host for Charlotte's NBC television affiliate. It was known as WRET-TV and then WPCQ-TV during his tenure there; it is now WCNC-TV. On the June 9, 2016, episode of The John Boy and Billy Big Show, John Isley ("John Boy") announced that Raiford had retired from the show, due to suffering a stroke the previous August that greatly affected his speech and mobility. Raiford had not delivered any commentaries during the intervening months, choosing to focus on his recovery instead.

[EX Q]: Passage: There were 45 entrants for the race, but only the quickest 30 drivers during the elimination trials would qualify for the race. The first day of trials was completed on the Monday before the race, 25 May. Caleb Bragg set the fastest official time on the first day, recording 1:36.8, though it was reckoned that Howdy Wilcox went quicker, but his time was not officially recorded. Ralph DePalma, a crowd favourite, struggled in his Mercedes and could only manage a quickest time of 1:47.4, slower than the 1:45 that it was predicted drivers would have to beat in order to qualify. Only fifteen of the drivers ran on the first day, and they continued with two session on the Tuesday. On the second day, three drivers set record times around the Speedway: first the 1912 winner, Joe Dawson, set an unofficial lap time of 1:34.8. Later in the day Teddy Tetzlaff completed a lap in 1:33.4, while Jules Goux finished the day as the fastest driver, with a time of 1:31.7. Tetzlaff's lap was completed in a Maxwell which was fuelled with a 50:50 mix of gasoline and kerosene; the other Maxwell, driven by Billy Carlson, set a time of 1:36.6 fuelled by a combination of kerosene and lucubrating oil, with no gasoline. Ray Harroun, who had won the inaugural Indianapolis 500 in 1911, designed the Maxwell car, and was given $10,000 () by the company's president as a reward for the cars qualifying with sub-1:37 times.

[EX 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.
