56.
A scientist is performing an experiment with an object falling in air. His hypothesis is that the time the object takes to fall will be directly proportional to the height from which the object is dropped; if this is true, a graph of fall time versus height will be a straight line. When he graphs his data, the graph is clearly curved, not a straight line. He decides that there must be an error in his measurements and concludes that the hypothesis should be accepted.

Explain how three of the four limitations of science apply to this experiment and to the scientist's conclusion.
