Great! Your answer is right!One signal is due to the protons bound to carbon 2 and 5, the second is due to the protons bound to carbons 3 and 4.
It is the number of groups of equivalent protons that determins the number of signals in a 1H NMR spectrum.
Here is another opportunity for you to practice the identification of equivalent protons:
