Answer to Question 1

The existence of an interaction means that the effect on one factor depends on the levels of the second factor. Thus, the effect of the factor is not consistent but rather varies as the second factor changes. The main effect for the factor is obtained by averaging over all of the different effects and, therefore, probably does not accurately describe any of them.
