I didn't see any discontinuity. Maybe the OP corrected the image?
EDIT: NM I see your point. The wording is horrible. The problem is not fully stated no matter how you rearrange the given data. The tuning fork frequency is obviously needed. The 3 Hz is a beat, not the tuning fork frequency. Etc.

why I couldnt hear 3hz tuning fork?
