Answer to Question 1

Laboratory experiments and theory show that fusion reactions produce neutrinos. Therefore, scientists predict that neutrinos should come from the Sun if fusion is occurring in its core. Theories predict how many and what type of neutrinos should be observed. Thus, the observations that confirm this prediction support the theory.

Answer to Question 2

C
