Example Input: Question: Was Forbes or the Guardian founded first? Passage:"The Lazy Song" has received generally mixed reviews from contemporary music critics. Eric Henderson of Slant Magazine noted that in song Mars "paints a portrait of Al Bundy as a young man" and Andy Gill of The Independent classified the song as a "laidback acoustic groove". Tim Sendra of AllMusic said it was one of the tracks from Doo-Wops & Hooligans that captured the laid-back groove. Scott Mervis of the Pittsburgh Post-Gazette described the song as a "Jason Mraz/Sugar Ray-style reggae." Sean Fennessey, a reviewer of The Washington Post, felt the song was written in a "quality that is both endearing and damning". A mixed review came from Digital Spy reviewer Lewis Corner, who commented that the song is a "summery ditty more head-boppable than a Churchill nodding dog, which, given his current state of mind, is probably about all he could muster", giving it three stars out of five. and from Blues & Soul magazine who called it "reggae tinged" and found it to be "somewhat of a filler but for the likes of Peter Andre" is great. Entertainment Weeklys Leah Greenblatt considered that "other modes suit him less well; The Lazy Song is perhaps better left to Jason Mraz". Alexis Petridis of The Guardian, gave the song a negative review, writing that "The Lazy Song" "gets no further than the second verse before Mars – nothing if not keen to keep his fans abreast of his every activity in a world of 360-degree connectivity – announces that he's planning on having a wank". Nick Messitte writing for Forbes criticized the single for copying the "happy-go-lucky meanderings of Jason Mraz's "I'm Yours", but also using the same pattern as Travie McCoy and Mars' "Billionaire" (2011).

Example Input: Question: Did Masashi make his debut before Tosanoumi? Passage:Oso was interested in sumo from a young age, as his father was the director of the Ibaraki Prefecture sumo association. He won national amateur titles at high school and at Senshu University, where he was a rival of Tosanoumi. He made his professional debut in January 1993 in the third makushita division, as due to his amateur achievements he had been given makushita tsukedashi status. He breezed through makushita undefeated with two consecutive 7–0 scores to earn promotion to the second jūryō division, whereupon he changed his shikona from Oso to Musōyama, meaning "twin warrior mountain." He made his debut in the top makuuchi division in September 1993. It took him only seven tournaments from his professional debut to make the san'yaku ranks, debuting at sekiwake in March 1994. In September he won his first eleven matches, finishing as runner up to Takanohana with a fine 13–2 record. Over the next few years he was regularly ranked at either sekiwake or komusubi, but was unable to make the next step up. He suffered a number of injuries, including a dislocated shoulder and a persistent problem with his left big toe which affected his speed of movement.
