Before starting the engine in a cold environment, a two-step warming procedure is recommended. How many steps does it include?

• A. One
• B. Three
• C. Four
• D. Two

Answer: (D)

A two-step warming procedure means there are two distinct actions to take before starting the engine in a cold environment. The term itself indicates the exact number of steps, so two is the correct count. Doing two steps helps ensure engine oil and coolant circulate and start warming up before the engine faces load, which reduces wear and improves starting reliability in cold weather. Saying there are any other number of steps would contradict the idea of a two-step process, so one, three, or four steps don’t fit.
