5- Although the idea seems contradictory, science cannot prove a hypothesis to be true. Why?
Group of answer choices

Science is a human endeavor, and like all human endeavors, it is limited by human understanding.

All true hypotheses will be rejected by the scientific method because they can be proven false.
