Quizplus · Accepted Answer

Bright room lighting should be controlled using constancy of conditions instead of elimination because it is a physical variable that cannot be completely eliminated without affecting the overall environment of the room. Instead, the lighting should be kept consistent throughout the experiment to ensure that it does not impact the results. For A, C, and D, these are external factors that can be eliminated or minimized through proper experimental design and control.
