Answer to Question 1

ANS: A
The exact positions of pins and pinholes vary for each gas. Unless the pins and holes align per-fectly, the yoke nipple cannot seat in the recessed valve outlet. Six holes and pin positions con-stitute the total system. Because overlapping holes cannot be used, there are 10 possible pin com-binations.

Answer to Question 2

ANS: B
