Question

the cylinder leakage gauge tells you the ______ of air leaking from the cylinder. select one: a. percentage b. volume c. approximate fraction d. speed

Explanation:

A cylinder leakage gauge measures the percentage of air leaking from the cylinder. It is a common diagnostic tool in engine analysis. Volume is not typically measured in this context as the gauge is more about proportion. An approximate fraction is too vague compared to a percentage measurement. Speed is not relevant as the gauge is about the amount (in percentage terms) of leakage, not how fast the air is escaping.

Answer:

a. Percentage
