Question

Quizplus · Accepted Answer

A scientific law is a summary of a pattern in nature that is observed repeatedly, and it does not explain why the pattern occurs. Therefore, option E is the correct statement, as it describes the nature of a scientific law. Option A is incorrect because a scientific law summarizes observations, but it does not necessarily provide factual information. Option B is also incorrect because a theory is a well-substantiated explanation of natural phenomena, but it is not considered an absolute fact. Option C is incorrect because a hypothesis is a testable prediction based on observations, and it is not necessarily difficult to test. Option D is incorrect because an observation simply describes a phenomenon and does not provide an explanation.
