A student who had once lived in Alaska describes the following personal experience: The shaking of the ground beneath my house caused compaction of the particles, which caused a later mass movement resulting in my house breaking apart.

Evaluate this statement.
A) It is probably true, except that it is unlikely that the mass movement would be strong enough to break a house apart.
B) It is probably false. Most breaking action occurs during an earthquake, not after the earthquake.
C) The entire statement is true.
D) It is more likely that liquefaction, caused by shaking regolith that contains water, caused the mass movement than it is likely that it was caused by compaction.

A) compaction, both wet and dry.
B) liquefaction, both wet and dry.
C) compaction when wet, and liquefaction when dry.
