Question

scientists have always been fascinated by dinosaurs... (passage with ocr errors) what is the difference between a theory and a scientific law?

• a theory has been tested many times; a law has never been tested.
• a theory is proven true under all conditions; a law is a simple explanation of phenomena... (remaining options with ocr errors)

Explanation:

To determine the difference between a theory and a scientific law, we analyze each option:

• Option 1: Incorrect. A theory is not "just a hunch" and a law is not "always tested" in the way described. Theories are well - supported explanations, and laws describe phenomena.
• Option 2: Incorrect. The description of theory and law here is reversed. Theories explain phenomena (often with many conditions considered), and laws describe what happens (often under all conditions).
• Option 3: Incorrect. A theory is a well - supported explanation (not an "educated guess" in a negative sense) and a law is a description of a phenomenon that is always true under the right conditions.
• Option 4: Correct. A theory is a widely accepted explanation of a phenomenon (it is based on a large body of evidence and explains why things happen). A law is a statement that describes a natural phenomenon and is always true under the conditions it applies to (it describes what happens).

Answer:

D. A theory is a widely accepted explanation; a law is always true under the conditions. (Note: Assuming the last option is D as per the standard multiple - choice formatting where the fourth option is the correct one based on the analysis. If the option labels were different, adjust accordingly, but based on the content, the option with the description "A theory is a widely accepted explanation; a law is always true under the conditions" is correct.)
