Answer to Question 1

C
An F ratio is calculated for each main effect and the interaction.

Answer to Question 2

C
Intersecting lines would indicate that the interaction is significant. Flat lines would indicate that one of the main effects was not significant. Circles are not seen on graphs of this type.
