The Müller-Lyer illusion exists in cultures in which there are ________.

A) more men than women
B) more women than men
C) lots of telephone poles
D) buildings with lots of corners

The Müller-Lyer illusion is more prevalent in cultures with environments that have many straight lines and right angles, such as those found in urban areas with buildings that have lots of corners. This is because the illusion is thought to be influenced by the visual context of one's environment, particularly those with carpentered corners, which are common in many buildings.
