You are presented with the question "cycles of freezing and thawing water can cause what?" and the following answer choices: 
- clean county roads
 - exposure to cold
 - severely damaged roads
 - Physical weathering
 - colder weather
 - Metling snow
 - smooth safe roads
 - rough riding

Now knowing that cycles of freezing and thawing water cause ice wedging and an ordinary ice road is therefore severely damaged by cracks induced by the traffic, choose the best answer.
