Parallel resonance by varying frequency
I understood how it responds by varying the other parameters (L , C...) but how does it respond to changes in frequency? (Honestly speaking, I barely get a thing they're trying to say in my textbook)

What do you mean by changing the frequency?
You change the loads (resonant) frequency by changing L, R, C etc.
You change the source frequency by changing the frequency of the A.C. input.
When they match resonance occurs.

The current in the inductor comes from the capacitor, and the current in the capacitor comes from the inductor, and very little current is drawn from the external circuit at resonance. It is this high circulating current between L and C that is responsible for the high peak in voltage levels at parallel resonance.
