Question

in a large aquarium, which staff member is interacting with a midlevel category member? a marine biologist studying the function of gills an ocean rehabilitation expert who is working with a freshwater electric eel an aquarium cleaner who has been watching their favorite fish an intern investigating mammals that reside in the ocean

Explanation:

A midlevel category member is a specific, common example within a broader category (here, "fish" is the midlevel category, as it is more specific than "aquatic organisms" but broader than a single species like electric eel or a trait like gills). The cleaner interacting with their "favorite fish" refers to a general fish (midlevel category), while the other options focus on specific traits (gills), a non-marine species (freshwater electric eel), or a narrower subcategory (ocean mammals).

Answer:

C. an aquarium cleaner who has been watching their favorite fish
