During a science lesson, students read a passage about stars and their properties. The text notes luminosity, size, temperature, mass, and composition. The passage best demonstrates which text structure?

• A. Enumeration
• B. Cause and effect
• C. Compare and contrast
• D. Problem-solution

Answer: (A)

This text structure is about listing related items in a straightforward sequence. The passage presents several star properties—luminosity, size, temperature, mass, and composition—in a simple catalog of attributes. That kind of presentation is an enumeration, where the author numbers or lists items that belong to the same category without arguing cause-and-effect, making comparisons, or presenting a problem and its solution.

If it were cause and effect, you’d see a link explaining how one property leads to another. If it were compare and contrast, there would be explicit comparisons between stars or properties. If it were problem-solution, there would be a challenge described and a remedy proposed. Here, the focus is just listing what describes stars.
