Answer to Question 1

the chin was too flexed

Rationale: If the teeth superimpose the odontoid process, the chin needs to be extended more to align with the base of the skull

Answer to Question 2

radiographic contrast increasing

Rationale: Increased collimation of the primary beam results in: an increase in radiographic contrast, decreased radiographic density, decreased patient dose, and decrease in scatter radiation.
