A key step in developing a new explanation is:

A) making observations about a place or process
B) asking questions about the observations
C) proposing an interpretation that can be tested
D) collecting new observations to test predictions

These steps are fundamental to the scientific method and are interconnected in the process of developing and refining explanations and theories.
