Consider the following dialogue between two people:

User 1: Hi, I'm having some trouble with my computer.
User 2: What seems to be the issue?
User 1: I don't really know how to describe it.
User 2: Is it a display issue?

There are three phases of this dialogue: problem identification, joint solution exploration, and gathering of additional information. Of those three phases, which phase is this dialogue currently in? I want the entire output in JSON format.
