30、In 1772,Captain Cook set sail to look for a theorized great southern continent.Although they could not manage to reach the Antarctic owing to the ice,he predicted that if it did exist,it would have to be a wasteland.6 In 1776,Captain Cook started his third Pacific voyage,searching for the Northwest

42、reason I think it was the greatest sea escape.LP:When you put it that way I suppose it was a great achievement.Captain Bligh was certainly excellent in the way he kept the men occupied and tried to take their minds off their troubles.In addition he treated everyone the same when it came to food or w
