Answer the following question given this paragraph: 

There are sometimes signs that a large earthquake is coming. There may be small quakes, called foreshocks . These can occur a few seconds to a few weeks before a major quake. Unfortunately, foreshocks are not very useful for predicting large earthquakes. Many quakes do not have foreshocks. Also, small earthquakes are not necessarily followed by a large earthquake.


Q: A small quake preceding a large quake is called what?

 Choices:

- aftershock

- warning shock

- preshock

- foreshock

A:
foreshock
