Final answer:
Carla can use her olfactory sense and binocular depth cues to enjoy and navigate the carnival. The opponent-process theory of color perception may affect how she perceives colors.
Step-by-step explanation:
Carla can use her olfactory sense to enjoy the carnival by experiencing the pleasant smells of cotton candy, popcorn, and other delicious treats. However, if she has a supertaster ability, some strong flavors might be overwhelming for her, which could hurt her enjoyment. To successfully navigate the carnival, Carla can use binocular depth cues to estimate distances and perceive depth, helping her avoid bumping into people or objects. The opponent-process theory of color perception may not have a direct impact on Carla's enjoyment or navigation, but it could affect how she perceives the vibrant colors of the carnival.
