Text Structure: Problem & Solution and Description: Fifth Grade English Student Guide

Understanding problem-and-solution and descriptive text structures enables you to analyze how engineers tackle crises and how authors paint rich conceptual portraits of scientific subjects.

The Problem-and-Solution Text Structure

In a problem-and-solution text structure, the author introduces a dilemma, crisis, or challenge, and then outlines one or more methods proposed or implemented to resolve it. This structure is prevalent in engineering, environmental science, and social studies texts.

+--------------------------------------------------------------+
|             PROBLEM-AND-SOLUTION ARCHITECTURE                |
|                                                              |
|   [ THE PROBLEM / DILEMMA ]                                  |
|   Coastal cities face severe flooding from rising sea levels |
|   and storm surges.                                          |
|                                                              |
|                            |                                 |
|                            v                                 |
|   [ PROPOSED SOLUTIONS & MEASURES ]                          |
|   * Construct movable sea barriers (e.g., Thames Barrier).   |
|   * Restore natural coastal wetlands to absorb wave energy.  |
|   * Elevate roadways and reinforce sea walls with granite.   |

Signal Words for Problem and Solution

Key transitional phrases signal this structure: the dilemma, problem, crisis, difficulty, challenge, solve, solution, remedy, propose, resolve, countermeasure, and overcome.

The Descriptive Text Structure

The descriptive text structure provides detailed characteristics, features, and sensory attributes of a specific topic, person, or animal. Unlike chronological texts that follow time, descriptive texts explore a topic through spatial arrangement or categorized traits.

Signal Words for Description

Descriptive texts rely on sensory modifiers, spatial prepositions, and classification phrases: for example, characterized by, features include, consists of, for instance, in terms of size, located adjacent to, and specifically.

Exercises and Solutions

Exercise 1: Classifying Text Structures. Identify whether each passage represents a problem-and-solution structure or a descriptive structure, and cite the signal words that prove it: Passage A: "Municipal drinking water in the rural community contained hazardous levels of mineral sediment. To overcome this public health challenge, local engineers designed an innovative sand-filtration plant that removes ninety-nine percent of particulate matter." Passage B: "The monarch butterfly features distinctive orange wings edged in velvety black borders with delicate white spots. With a wingspan stretching four inches, this fragile insect possesses compound eyes and sensory antennae capable of detecting nectar odors from miles away."

Solution 1: Passage A represents a Problem-and-Solution structure; the problem is "hazardous levels of mineral sediment" in drinking water, and the solution is signaled by "To overcome this public health challenge, local engineers designed an innovative sand-filtration plant." Passage B represents a Descriptive structure; it provides sensory traits, colors, and anatomical measurements of the monarch butterfly, using descriptive language like "features," "distinctive orange wings," and "wingspan stretching four inches."

Exercise 2: Crafting a Problem-and-Solution Passage. Write a three-sentence informational paragraph using the problem-and-solution structure to describe how urban planners solve the problem of traffic congestion in growing cities.

Solution 2: Rapid population growth in modern metropolitan areas has produced severe traffic congestion, causing hours of commuter delays and dangerous vehicle emissions. To address this mounting urban dilemma, transportation planners have expanded dedicated electric light-rail networks and created protected express bus corridors. By providing residents with rapid, affordable public transit alternatives, cities have significantly decreased the volume of commuter vehicles on downtown highways.
