Which of the following best explains why scientific knowledge is considered long-lasting?

• It is based on unchanging facts.

• It is open to change as new evidence or interpretations are encountered.

• It is always correct and never questioned.

• It is based solely on historical data.

How does empirical evidence contribute to scientific explanations?

• It provides a single observation that supports a theory.

• It is the cumulative body of observations of a natural phenomenon.

• It is based on assumptions rather than observations.

• It is used to confirm pre-existing beliefs.

What role does debate and confirmation play in the development of scientific knowledge?

• It prevents any changes to existing theories.

• It ensures that scientific knowledge is the result of thorough examination and agreement.

• It allows for the immediate acceptance of new ideas without scrutiny.

• It discourages collaboration among scientists.

How can empirical evidence be used to challenge an existing scientific theory?

• By providing anecdotal evidence that contradicts the theory.

• By presenting a single observation that supports the theory.

• By accumulating a body of observations that do not align with the theory.

• By ignoring the existing theory altogether.
