A rotary mower cuts grass when the whirling mower blade ___ the grass.

Explanation:
Rotary mower cutting happens when the blade makes contact with the grass. The blade is spinning very fast, and its sharp edge strikes the grass as it whirls by, shearing it off to create the cut. The air flow helps bring the grass into contact and supports the cutting action, but the actual cut comes from that impact of the blade against the grass. Pushing would move grass without cutting, lifting describes the air action rather than the cut, and while slicing is related to the edge’s action, the essential moment that creates the cut is the blade’s impact.
