Sometimes, new but well-tested experimental result may go against commonly accepted scientific ideas. which statement best justifies the need to revise the existing ideas when this happens? a) scientific theories continually change over a period of time. b) a scientific theory must explain as many findings as possible. c) accepted scientific ideas are usually based on the latest experiments. d) the new results usually show that the accepted ideas were completely wrong.

The correct answer is A) Scientific theories continually change over a period of time.
Throughout the history of science, there have been numerous theories and experiments that were well-tested and explained but were contradicting the current scientific consensus. It is often very difficult for the scientific community to accept revolutionary ideas like Darwin's theory of natural selection, or Einstein's theory of relativity because those ideas challenge the common understanding of science. But, in order for science to progress and thrive, new ideas and findings should always be taken into consideration.
