Identifying Text Structure Assessment worksheet featuring three passages with corresponding text structure options.

Let's solve the "Identifying Text Structure Assessment" by analyzing each passage and determining its text structure. The four possible structures are:

- Sequence – describes a series of steps or events in order.
- Cause and Effect – explains why something happens (cause) and what results from it (effect).
- Problem and Solution – presents a problem and then offers a way to fix it.
- Compare and Contrast – shows how two or more things are similar and/or different.

1. "Hunters of the Sea"

Passage Summary:
This text talks about sharks and orcas. It points out their similarities (both are carnivores, have smooth bodies, sharp teeth) and differences (sharks lay eggs, orcas give live birth; orcas have bones, sharks have cartilage).

Analysis:
The passage clearly compares sharks and orcas by listing what they have in common and how they differ.

✔ Correct Text Structure: Compare and Contrast

2. "Volcanic Eruption!"

Passage Summary:
This is a step-by-step guide on how to make a volcano erupt using baking soda, vinegar, food coloring, and dirt. It gives instructions in order: set up the bottle, add ingredients, pour vinegar, watch the result.

Analysis:
The passage follows a clear chronological order of actions — it’s a how-to or procedural text.

✔ Correct Text Structure: Sequence

---

3. "Disappearing Forests"

Passage Summary:
It starts with people cutting trees for wood. Then it explains that when trees are cut too fast, animals lose homes, rain washes dirt into streams, new trees can’t grow, fish can't survive — leading to barren landscapes.

Analysis:
This passage explains what happens when trees are overcut (problem), and then details the chain of negative consequences (effects). It shows cause (deforestation) and effect (ecological damage).

✔ Correct Text Structure: Cause and Effect

---

✔ Final Answers:

1. Hunters of the Sea → Compare and Contrast
2. Volcanic Eruption! → Sequence
3. Disappearing Forests → Cause and Effect

📝 Explanation Recap:

- Compare and Contrast: Used when discussing similarities and differences between two subjects (e.g., sharks vs. orcas).
- Sequence: Used when describing steps in a process (e.g., making a volcano).
- Cause and Effect: Used when explaining how one event leads to another (e.g., deforestation → soil erosion → loss of habitat).

These structures help readers understand how information is organized in nonfiction texts.
