premise: Lost Mom<br>Danielle loves to travel with her mom. One year they went to Mt Pilatus in Switzerland. At the top Danielle got separated from her mom. After two hours of searching she gave up and went down to the bottom. There was her mom relaxing in a local cafe.
hypothesis: Danielle's mother left the peak of Mt. Pilatus as soon as she reached it.
reason: The original statement does not state that Danielle's mother never reached the peak of Mt. Pilatus, only that Danielle was separated from her at the peak. Danielle's mother could have left the peak as soon as she reached it, assuming her daughter would realize she was leaving.
