Question

what is a hypothesis? a well - tested explanation for a wide range of observations. an observation that is difficult to understand or explain. a proposed explanation for an observation that can be tested. a scientific fact that has been proven to be true without doubt.

Explanation:

To determine the correct definition of a hypothesis, we analyze each option:

• The first option describes a theory (a well - tested explanation for a wide range of observations).
• The second option does not fit the definition of a hypothesis; it seems to describe something that is a mystery or an unexplained observation.
• The third option: A hypothesis is a proposed explanation for an observation that can be tested. This matches the scientific definition of a hypothesis.
• The fourth option (partially visible) seems to describe a scientific fact that has been proven, which is not a hypothesis.

Answer:

The third option (the blue box with the text "A proposed explanation for an observation that can be tested")
