Answer

Brief Explanations:

The Mercalli scale rates an earthquake based on the observed effects and damage it causes at different locations. It has 12 levels of intensity, not twenty. The scale that rates an earthquake based on total energy released is the Richter - like magnitude scales. Using data from three or more seismographs is related to determining the epicenter and magnitude on other scales, not the Mercalli scale's main characteristic.

Answer:

The scale rates an earthquake according to how much damage it causes.
