Example Input: Question: Of the two artists who influenced Jones, which was the eldest? Passage:Carroll Nathaniel Jones III (July 2, 1944 - June 22, 2017) was an artist in the style of American realism. Carroll grew up in New Providence, New Jersey where his father, an illustrator for Life (magazine), was his first art teacher. He taught Carroll techniques of the Old Masters, who emphasized light, perspective, and composition. Carroll went to school in New York City (NYC) and enrolled in the Phoenix School of Design at age 17. He later attended Hartford Art School and became a commissioned portraitist for 10 years. His work, Church Window was recognized in the New York Times, and he moved away from portraits to recreate scenes that sparked memories of his childhood. He was most influenced by Andrew Wyeth and Edward Hopper. The Coe-Kerr Gallery of NYC and Whistler's Daughter Gallery of New Jersey represented him, as well as contemporaries Wyeth and Hopper. Malcolm Forbes, Frederick R. Koch, Stephen Sondheim, William Schuman, and Jean Shepherd held private collections of his work. He exhibited at Newark Museum and Trenton Art Museum in New Jersey, and in universities, galleries and museums in seven states by his mid-thirties. His work is part of the permanent collections of Seton Hall University and Newark Museum. Art critic Marion Filler considered his work Magic realism, a quiet movement made popular in America beginning in the 1920s by Hopper, and related to Surrealism.

Example Input: Question: Of the women the song was compared to in Slant Magazine, who was born first? Passage:Kerri Mason of Billboard called the song a harmonious ballad which, along with the single "4 Minutes", "might be some of her best work yet". She also said that the song sounded familiar and compared it with Timbaland's remix of the 2008 single "Apologize". Caryn Ganz from Rolling Stone believed the song has a "melancholy pining". Stephen Thomas Erlewine from Allmusic held the view that "the icy heartbreak of 'Miles Away'" was "a worthy successor of Justin Timberlake's 2006 single 'What Goes Around.../...Comes Around'". Sal Cinquemani of Slant Magazine said that the song has the typical ensuring quality of the production of Timbaland and Justin Timberlake, and bears the "pair's distinct, modern stamp, making Hard Candy more than just a throwback to Donna Summer, Anita Ward, and Quaaludes." Chris William from Entertainment Weekly made the observation that "Miles Away" was one of the "few actual confessions on this dance floor [Hard Candy]enough to give the tabs speculative fodder." He also compared the song to "What Goes Around.../...Comes Around". Jim Farber of the New York Daily News called it the album's most beguiling tune.
