A woman using a whisk to blend the liquid contents in a measuring cup.
The woman prepares eggs for an omelet.
Just because a woman is using a whisk to blend the liquid contents in a measuring cup doesn't mean that the woman prepares eggs for an omelet.  The woman could be blending liquid contents for reasons other than preparing eggs for an omelet.
