Answer

Providing absolute proof of all scientific claims.

Question 20

The role of theories in predicting natural phenomena is:

Accepted Answer

Essential for the advancement of scientific knowledge.

Answer

Overstated, as theories can only provide tentative explanations.

Answer

Unimportant, as empirical data alone is sufficient for understanding nature.
