Answer to Question 1

B

Answer to Question 2

The process of science involves asking a question and then forming testable hypotheses in order to gather evidence either to support or to refute it. So-called cherry picking of evidence to support an idea and ignoring evidence that may refute it does not advance knowledge and is not the scientific method.
