Final answer:
The words opaque, vivid, brilliant, and shiny all pertain to the sense of sight, which is one of the five human senses. These adjectives are used to describe visual attributes that are perceived with our eyes.
Step-by-step explanation:
The words opaque, vivid, brilliant, and shiny all relate to the sense of sight. These adjectives describe visual qualities of objects: 'opaque' means not transparent or unable to be seen through; 'vivid' indicates something that is very clear, detailed, or expresses a strong, bright color; 'brilliant' is used for very bright or radiant light; and 'shiny' refers to something with a smooth surface reflecting light. The human senses include hearing, sight, taste, touch, and smell. In this case, the adjectives correspond to the sense of sight because they describe characteristics that we perceive with our eyes.
