Which of the following is an example of a landmark related to surface texture?

The correct answer highlights a change in surface texture underfoot on a sidewalk as an example of a landmark related to surface texture. This is because landmarks associated with surface texture are tactile indicators that can help individuals with orientation and mobility. By feeling a change in texture, a person can gain important information about their environment, such as transitioning from a sidewalk to grass or identifying different walking surfaces that may indicate proximity to buildings or paths.

Surface texture landmarks are particularly useful for individuals with vision impairments, as they rely on touch to navigate and understand their surroundings. The sensation of different materials beneath their feet can help inform them about their location and guide their movements safely.

In contrast, the other choices involve visual or auditory landmarks, which do not directly relate to tactile perception in the same way. A building with a unique design is primarily a visual cue, while a different color of paint on a wall and a sound made by traffic also rely on visual and auditory senses, respectively, rather than tactile feedback.
