This is just asking you to use your finger to trace where you are on the phase diagram. Think back to when you learned about graphs. Treat #T#, the temperature, as your #x# value, and #P#, the pressure, as your #y# value.

Now point to where #T = -57^@ "C"#, and #P = "2 atm"#. Did you point here?

So then, what single phase is here?
