Answer to Question 1

the two laminae

Rationale: The union of the two laminae most posteriorly will close off the posterior vertebral arch.

Answer to Question 2

the gray demonstrated by each pixel

Rationale: Bit depth influences the range of gray shades that can be demonstrated. The numerical value of the gray for each pixel is a bit. The greater the bit depth the greater the contrast resolution.
