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).

Question: What was the date of the Siege of Port Arthur? Passage:The cruiser Bayan (Russian: Баян) was the name ship of the four armoured cruisers built for the Imperial Russian Navy in the first decade of the 20th century. The ship had to be built in France because there was no available capacity in Russia. Bayan was assigned to the First Pacific Squadron after completion and based at Port Arthur from the end of 1903. She suffered minor damage during the Battle of Port Arthur at the beginning of the Russo-Japanese War of 1904–05 and supported destroyers as they patrolled outside the harbour. After bombarding Japanese positions in July 1904, the ship struck a mine and was out of action for the next several months. Bayan was sunk during the Siege of Port Arthur and was then salvaged by the Japanese after the war.
