Segall's research indicates that people who come from carpentered environments are ______.

A) less susceptible to the Müller-Lyer illusion
B) more susceptible to the Müller-Lyer illusion
C) more susceptible to the horizontal-vertical illusion
D) less susceptible to the horizontal-vertical illusion

Segall's research found that people from carpentered environments, which are characterized by straight lines, right angles, and square corners, are more susceptible to the Müller-Lyer illusion. This is because their visual system is accustomed to interpreting angles and lines in a certain way, making them more likely to be deceived by the illusion.
