The aperture on a camera is a hole or an opening through which light
is admitted. Besides letting in more or less light it controls the
depth of field. A small aperture gives a greater depth of field. It is
also referred to as the f number or stops. I assume that Sabrina meant
for you to decrease the aperture to cut down the total light entering
the camera and use the flash as a fill in light. You would need to use
your camera in manual mode as in automatic it would increase the
exposure time to compensate.

One can only suck it and see.
