When two or more waves with the same frequency and phase are made to superimpose, then the resultant amplitude increase. This situation is known as resonance.The bridge collapsed because it was bouncing at a large amplitude and this is the situation of resonance. Here the natural frequency of the bridge matched with the frequency of stomping boots. Hence, the right option for the 1st part is 'the same frequency as its natural frequency'.The situation explained in 2nd case also causes resonance and this resonance drove the oscillation larger and larger i.e. the amplitude increases. Hence, the correct option is 'larger and larger.If the soldiers break the step, then they are breaking the resonance so that the bridge does not bounce with large amplitude. Since, resonance only occurs when two frequency matches, therefore we can say to break the resonance, they have to march with a different frequency than the natural frequency of the bridge. Hence, the correct option is 'to a different frequency'.
