Answer to Question 1

increase in technical factors

Rationale: Pathologies such as ascites, pneumonia, congestive heart failure, edema, and rheumatoid arthritis are examples of additive pathologies that require an increase in technical factors.

Answer to Question 2

the chin was too flexed

Rationale: If the mandibular rami superimpose C1 and 2 it suggests that the patient's chin was too flexed.
