Question: Was Erich von Drygalski married when he led the German Antarctic expedition? Passage 1:After the success of Walt Disney Productions' first feature-length animated film Snow White and the Seven Dwarfs (1937), filmmaker Walt Disney himself made several attempts to adapt the fairy tale "Beauty and the Beast" by Jeanne-Marie Leprince de Beaumont into one of the studio's earliest animated feature films during the 1930s and 1950s. However, the project was continuously abandoned due to the fairy tale's "static" plot and main characters. The filmmaker was also concerned about the "unnecessary intensity" required to depict Belle's imprisonment. Inspired by the unprecedented success of The Little Mermaid (1989), Walt Disney Studios chairman Jeffrey Katzenberg green-lit another attempt at adapting "Beauty and the Beast" under the direction of Richard Purdum. However, Katzenberg did not approve of Purdum's dark, somber version of the fairy tale, and ultimately ordered that it be restarted from scratch in favor of creating a Broadway-style musical film starring a strong heroine, more similar to The Little Mermaid. Opting instead for a "feminist twist" on the original story, largely in response to critics' negative reception to Ariel regarding her pursuit of Eric being her overall character, Katzenberg hired television writer Linda Woolverton, who had never written an animated film before, to write the film's screenplay.
 Passage 2:Liverpool began their preseason in the same manner as last year, a visit to Tranmere Rovers on 12 July. Liverpool won 0–4 with goals from James Milner (from the penalty spot), Marko Grujić, Pedro Chirivella, and Ben Woodburn (from the penalty spot as well.) The Reds next trip was to Wigan Athletic on 14 July where they drew 1–1 going 1–0 down early, but the equalizing goal coming in first half stoppage time from new signing Mohamed Salah. On 19 July, Liverpool played their first match of the 2017 Premier League Asia Trophy friendly tournament in Hong Kong against Crystal Palace. The Reds won 2–0 thanks to goals from another new signing, Dominic Solanke, and Divock Origi. The Reds advanced to the final, played on 22 July, the day after announcing new signing Andrew Robertson on a deal from Hull City, against Leicester City. Liverpool won the tournament defeating Leicester in the final 2–1, despite conceding first, due to goals from Salah and Philippe Coutinho.
 Passage 3:While Borchgrevink, steering towards the Southern Cross, was on target for Antarctica, a German, Swedish and British expedition was prepared for the Southern Ocean. Germany built the expedition ship Gauss for 1.5 million marks at the Howaldtswerke in Kiel. On the model of the Fram, the Gauss, which weighed 1,442 tonnes (1,419 long tons) and was long, had a round hulk in order to withstand the ice pressure. The Gauss had three masts and one auxiliary engine of 275 horsepower (205 kW). With a 60-strong crew, it could operate for almost three years without any help. From 1901 until 1903, Erich von Drygalski led the German Antarctic expedition and carried out extensive studies mainly in the southern part of the Indian Ocean. The Swedish expedition under the command of Otto Nordenskjöld used the old Antarctic weighing only 353 tonnes, which had already been used by Borchgrevink in 1895. The expedition intending to overwinter at the Antarctic Peninsula was ill-starred from the beginning. In 1902, the Antarctic sank. Fortunately, the Argentine gunboat Uruguay rescued all crewmembers. Also Great Britain prompted Dundee Shipbuilders to build a ship for Robert Falcon Scott's expedition. The Discovery weighed 1620 tonnes, was long and had an auxiliary motor of 450 horsepower. Nevertheless, during the research the ship froze in. Only the relief ship Morning, sent by the British Admiralty, was able to free the Discovery and with Terra Nova escorted the Discovery back home. The reunion with the Antarctic ice was undertaken by a Scottish expedition led by the naturalist William Speirs Bruce. Bruce had worked with the whale catchers Balaena and Active in the Southern Ocean in 1892 to 1893. He hoped that he could acquire the field-tested Balaena but found the ship too expensive, buying instead the Norwegian whale catcher Hekla for £2,620, a ship that had sailed under the Danish flag along Greenland's coast in 1891 and 1892. For another £8,000 he had the ship repaired and provided it with a new engine. Under the new name Scotia, this ship completed its way into the Southern Ocean and was very successful thanks to dredging and trawl catches at great depth in the Weddell Sea and off the coast.
