Answer 1

At the 500-hour maintenance interval, inspecting the spark plugs is a common practice to assess the condition of the engine's combustion process. Other maintenance tasks may vary based on the specific schedule set by the manufacturer.

Step-by-step explanation:

At the 500-hour maintenance time interval, the activity that should typically occur is: Inspect the spark plugs. This is a regular maintenance task for many types of engines, including those in cars, trucks, and machinery. Inspecting the spark plugs can reveal the condition of an engine's combustion process. If the spark plugs are fouled or damaged, they may need to be cleaned or replaced to ensure the engine's optimal performance. Other tasks, such as replacing the engine oil, cleaning the air filter, and rotating the tires, may also be recommended at different intervals depending on the manufacturer's maintenance schedule.
