Answer

Decrease

Work Step by Step

We know that $\omega=\frac{1}{\sqrt{LC}}$. This equation shows that the resonance frequency is inversely proportional to the capacitance. Thus, when a second capacitor is added in parallel with the first capacitor the total capacitance is increased and consequently the resonance frequency decreases.
