Correct Answer: B
Rationale: The female pubic arch is wider (greater subpubic angle, ~90-100°) than the male’s (~50-60°) for childbirth. This makes 'False' correct.

Correct Answer: A
Rationale: The support function of the skeleton involves providing a framework to shape the body, support structures, and bear weight (e.g., standing). B is movement, C is protection, and D is storage, making 'The body is shaped by the skeleton...' the support function.
