Question

read this excerpt from a passage.

aquaculture is the science and practice of growing fish for food; in other words, aquaculture is fish farming. like plant farmers, fish farmers oversee the natural life cycle of what they farm. fish farmers \plant\ (or hatch) their \crops\ (fish) in \fields\ (places called hatcheries). farmers feed the tiny fish and protect them from predators. in aquaculture, as in agriculture, food is produced in a controlled environment rather than gathered from the wild.

which type of definition does this excerpt provide?

comprehensive definition
narrative definition
extended definition
formal definition

Explanation:

Analyze the definition structure

The excerpt begins with a basic definition of "aquaculture" ("the science and practice of growing fish for food") and then expands on this concept. It uses analogies to traditional farming ("Like plant farmers...", "plant (or hatch) their 'crops'"), describes the process (feeding, protecting from predators), and contrasts it with wild gathering. This multi-sentence elaboration goes beyond a simple dictionary entry to explain the concept thoroughly.

Compare definition types

Using the Types of Definitions knowledge point, we evaluate the options:

• A Formal Definition (which is a mastered concept) is typically a single sentence stating the term, its general class, and its distinguishing characteristics.
• An Extended Definition goes much further, using paragraphs, examples, analogies, and detailed descriptions to help the reader fully grasp a complex term.
• "Comprehensive definition" and "narrative definition" are not standard rhetorical terms for this type of passage.

Determine the correct option

Because the passage uses an entire paragraph filled with analogies, descriptions of daily practices, and environmental contrasts to define "aquaculture," it is an Extended Definition.

Answer:

• comprehensive definition
• narrative definition
• extended definition (Correct answer)
• formal definition
