21 The intellectual foundation of science is rejection of all observations that disagree with theory. observation, faith, and acceptance. logical derivation entirely from fundamental principles. observation, logic, and skepticism. 22 Which of the following statements best represents the overall rationale for scientific investigation? Reality is comprehensible, and a limited number of fundamental principles governs the nature and behavior of the universe. There are certain patterns in nature from which future events can be predicted, but there are no underlying basic principles or laws. The universe is a hodgepodge of unrelated things behaving in unpredictable ways, but we must continue to observe it in case this behavior threatens Earth. The behavior of the whole universe is governed by our observation of it in such a way as to hide the fundamental truth. 23 One important characteristic of a scientific theory is that it is mathematical. consists of at least three separate hypotheses. can be tested by observation. need not have a connection with physical reality. 24 In science, if new observations disagree with a well established theory, then the new observations should be accepted as part of the overall incomprehensibility of the universe, and both the observations and the theory should be retained. the theory must be discarded immediately. the theory must be modified. the observations must be discarded. 25 A scientist observes a new phenomenon that disagrees with the scientist's own explanation or hypothesis.Following the scientific method, the correct procedure is to accept the disagreement as part of the fundamental incomprehensibility of the universe. modify the hypothesis. wait until someone develops an adequate
