Quizplus · Accepted Answer

Without depth perception, distance and depth would be impossible to judge accurately, making it difficult to discern any 3D aspects of the world. This would make driving, cycling or navigating around a room difficult. It would also make threading a needle hard, as judging the distance between the needle and thread would become challenging. Therefore, all options are correct, making Choice D the correct option.
