Why are scientific theories are modified?
A) Theories more than ten years old are usually out of date
B) New evidence that supports a revision prompts scientists to modify earlier theories
C) Scientists want to prove that the work of other scientists is wrong
D) So much information is available today that it is harder to focus research and disprove theories

How does publishing a theory help science?

B) His theory could not be accepted for two years.
C) Discussions and communication within the scientific community helped identify and address errors in his atomic model.
D) Communicating about his hard work to the scientific community forced him to share credit for his work with Bohr.
C) Discussions and communication within the scientific community helped identify and address errors in his atomic model.

If you were to propose a theory and research stated that part of it was wrong what would be the next course of action?
A) The researchers should propose modifications to the existing theory that take into account their new discoveries.
B) The researchers should propose disregarding the new results as they likely result from mistakes in the research.
C) The researchers should propose that different scientists conduct the same experiment to verify the original theory is wrong.
D) The researchers should propose the need for a completely new theory based on the latest research.
