Hi.<br/><br/>This is the dialogue from the movie 'Day after tomorrow'.<br/><br/>A:<i>This is the picture of Scotland when the temperature dropped.</i><br/><br/>B<i>:This thing looks just like a hurricane.</i><br/><br/>A<i>:<u>Only hurricanes don't form over the land.</u></i><br/><br/>Does the underlined sentence above mean: <i>Hurricanes can't form over the land without any other causes</i>?
