Answer to Question 1

glabella

Rationale: The CR is directed to exit the glabella on the PA skull to ensure the vertex is included.

Answer to Question 2

long scale contrast

Rationale: Higher kVp will increase the production of scatter radiation, which contributes to an image with a long scale contrast.
