Question

After completing 10 years of experimentation, a scientist reports a new scientific theory explaining the movement of sand on beaches. How do you know that this information is valid?

There were too few years of data.
The initial hypothesis was incorrect.
The problem was not important enough.
Theories develop through repeated experimentation.

Answer 1
