Answer

A Technician A Explanation 1. Evaluate Technician A's statement The valve train assembly includes valves and their operating parts, such as camshafts, lifters, pushrods, rocker arms, etc. Technician A is correct. 2. Evaluate Technician B's statement Engine displacement is determined by the bore and stroke of the engine. Extending the connecting rod does not increase displacement; it affects the stroke length but not directly the displacement. Technician B is incorrect.
