Input: Consider Input: Passage: The Lookout Mountain Incline Railway is a inclined plane funicular railway leading to the top of Lookout Mountain from the historic St. Elmo neighborhood of Chattanooga, Tennessee. Passengers are transported from St. Elmo's Station at the base, to Point Park at the mountain summit, which overlooks the city and the Tennessee River. It is just a short drive to three of Chattanooga's main tourist attractions, Ruby Falls, Cavern Castle, and Rock City. The railway is approximately in length (single-track except for a short two-track passing loop at the midway point, allowing operation of two cars at one time). It has a maximum grade of 72.7%, making it one of the world's steepest passenger railways. It obtained Historic Mechanical Engineering Landmark status in 1991. The cable system for the cars was made by the Otis Elevator Company.

Input: Consider Input: Passage: American singer and songwriter Mary J. Blige began her career as a backing vocalist for Uptown Records in the early 1990s. She has released 13 studio albums, eight of which have individually achieved worldwide multi-platinum status. The Queen of Hip-Hop Soul and Queen of R&B (publications often refer to her as both honorific titles), Mary J. Blige is uniquely credited as the first singer to release an album singing over hip-hop beats, which created the genre "hip hop soul" which fuses elements of soul, R&B and gospel style vocals over hip hop beats. Blige's genre-changing sound, in many ways, changed and shaped the sound for modern day R&B and blue-eyed soul artists. In September 1999, Rolling Stone bestowed her first album, What's the 411? (1992), as "genre-creating". Her discography consists of 14 top 10 Billboard 200 studio albums, two live albums, two remix albums and over eighty singles—including more than 20 as a featured artist. In 2009, Billboard magazine ranked Blige as the most successful female R&B/hip-hop artist of the past 25 years. In March 2017, Billboard magazine ranked her 2006 song "Be Without You" as the most successful R&B/hip-hop song of all time, as it spent an unparalleled 75 weeks on the Hot R&B/Hip-Hop Songs chart, 15 of those weeks at number one. In 2011, VH1 ranked Blige as the 80th greatest artist of all time. Moreover, she was ranked 100th on the list of "100 Greatest Singers of All Time" by Rolling Stone magazine. In 2012, VH1 ranked Blige ninth among "The 100 Greatest Woman in Music" listing.

Input: Consider Input: Passage: Witold Wilkosz was born on 14 August 1891 in Kraków to parents Jan, a Polish teacher, and Józefa née Vopalko. He showed a considerable talent for mathematics and languages since early childhood. He passed his final school-leaving Matura exam at the John III Sobieski High School (known in Poland as Gimnasium). He was a friend of fellow mathematician Stefan Banach. Before graduating from high school, he had written an article on semitology for which he was offered a scholarship and membership from Morgenländische Gesselchaft Scienctific Society, which enabled him to study at the University of Beirut. After a few months, he returned to Kraków and took up philology studies at the Jagiellonian University. After two years, he decided to change the course to mathematics, which he studied in Kraków and Turin. He received his doctoral degree on the basis of his dissertation on Lebesgue integrals and started to work as an academic teacher at his alma mater. In 1920, he obtained a habilitation and in 1936 he became a professor. He was arrested on 6 November 1939 by Nazi Germans alongside other prominent intellectuals and professors of Kraków in the infamous Sonderaktion Krakau. However, due to a serious illness, he was soon released together with nine other professors on 9 November. He returned home and began to work as a teacher. To supplement his income, he accepted another job at the Powszechny Zakład Ubezpieczeń Wzajemnych insurance company. In the following years, his health seriously deteriorated. He died of pneumonia on 31 March 1941.
