premise: Mini golf<br>Ann and her friend went mini golfing. The two had fun back and forth. Ann was winning at first. But then she hit the ball and it went in the water. She thought it was hilarious and got another ball.
hypothesis: Ann did not retrieve her ball that went in the water.
reason: The text says that Ann got a different ball after hitting her first ball into the water.  This means she didn't get her first ball out of the water and continue playing with it.  This is hard because the text mentions her hitting her ball into the water.
