The peaks due to all the 9 aromatic Hydrogen atoms lie in the range 7 - 8 ppm.
The peaks due to the two epoxide Hydrogens lie near 4 ppm.
There is no peaks in 1H NMR spectrum before 4 ppm.

Assign the NMR peaks below DIRECTLY onto the paper,
please!!!!
The impurities are water at 2.19 ppm and acetone at 1.6 ppm. So
just ignore those peaks. The peaks for the aromatic Hydrogens can
be grouped up to one (I believe they are the left most peaks at
around 7 to 7.5 ppm. Given that please assign the rest of the
hydrogens.
