premise: Grey<br>I went to the store to buy a new phone. The one I wanted was available. The salesperson showed me three different colors. I had a hard time choosing. I finally decided on the grey model.
hypothesis: They bought the grey model, but didn't deliberate for very long. 
reason: From the context we can see that they did deliberate for a while because it states they had a hard time choosing. The system likely could not equate hard time choosing with a long deliberation.
