A. During the winter when the roads are icy or snowy,
large amounts of salt are used to create B.safer driving

During the winter when the roads are icy or snowy,
large amounts of salt are used to create safer driving
conditions. The salt used on our roads is decreasing
the quality of the roads and creating runoff that is not
good for our environment.
Which is the best hypothesis in this scenario?
If adding large amount of salt is related to the quality roads then the quality of the road decreases.
Adding large amount of salt can result to low quality of roads.
The quality of road is not related to salt.
The quality of the roads increases when adding salt on the roads.
During the winter when the roads are icy or snowy,
large amounts of salt are used to create safer driving
conditions. The salt used on our roads is decreasing
the quality of the roads and creating runoff that is not
good for our environment.
Which is the relationship of the two variables?
negative relationship
positive relationship
no relationship
unrelated relationship
