Final Answer : B, Explanation :  Observations are used chiefly to confirm (or disconfirm) hypotheses; what observations should be made is often determined by what hypothesis is being tested. Observations do not always need be made directly by human beings. Instruments such as telescopes, barometers, and tape recorders can be used to aid in making observations.
