Explanation:

Question 18

Shadows and wrinkles on the green screen can interfere with the keying process. Bright subjects can be keyed depending on the background. High shutter speed affects motion blur. Even lighting is good for keying.

Track targeting determines which tracks are affected by operations. If a track is targeted, it can be selected or edited. Doubling volume is a volume - related operation. Disappearing from timeline is deletion. Automatic solo is a solo - related function.

Source patching controls which source tracks will be inserted into the timeline. The program monitor output is related to the output display. Which source clips are visible is more about visibility settings. Audio ducking volume is about audio mixing.

Answer:

A. Shadows and wrinkles on the green screen
