Resonance: In designing buildings to be erected in an area prone to earthquakes, what relationship should the designer try to achieve between the natural frequency of the building and the typical earthquake frequencies?
A) The natural frequency of the building should be exactly the same as typical earthquake frequencies.
B) The natural frequency of the building should be very different from typical earthquake frequencies.
C) The natural frequency of the building should be almost the same as typical earthquake frequencies but slightly higher.
D) The natural frequency of the building should be almost the same as typical earthquake frequencies but slightly lower.

To avoid resonance, which can amplify the effects of an earthquake and cause significant damage, the natural frequency of the building should be very different from the typical earthquake frequencies. This reduces the risk of the building entering into resonance with the earthquake's vibrations.
