What you'll learn
In plain words: structure is the plan of a text — what comes first, next and last, and why.
Think of a house. Before the walls and paint, there is a frame that holds it all up. Every piece of writing has a skeleton like that: the way the author arranges ideas from beginning to end. That skeleton is called text structure. In this lesson you will learn to:
- name the most common structures: sequence/chronological, compare-contrast, cause-effect and problem-solution;
- spot the signal words that reveal each structure;
- explain how one sentence, paragraph or section fits into the whole text and why the author put it there.
How it shows up on the GED. The Reasoning Through Language Arts (RLA) test is built around passages. These include articles, workplace memos, letters, speeches and short stories. Several questions on every test ask about structure. They usually sound like this:
- "Which statement best describes the overall structure of the passage?"
- "How does paragraph 3 contribute to the passage?"
- "Why does the author include the sentence '...'?"
- "Paragraphs 4 and 5 are mainly organized to..."
You will see these in three formats: multiple-choice questions, drag-and-drop tables (match each paragraph to its role) and drop-down sentences. The good news: structure questions follow patterns. Once you learn the patterns, you can answer them quickly and confidently.
Key terms
- text structure — the way a text is organized (a memo that lists steps uses sequence).
- sequence / chronological order — events or steps told in the order they happen (First... next... finally).
- compare-contrast — showing how two or more things are alike and different (two health plans, side by side).
- cause-effect — explaining why something happens (cause) and what happens as a result (effect). (Heavy rain → flooding.)
- problem-solution — describing a problem, then one or more ways to fix it (Traffic is bad → add bus lanes).
- signal words (transitions) — words that show how ideas connect (however, because, for example, then).
- topic sentence — the sentence, usually first, that states what a paragraph is about.
- flashback — a scene in a story that jumps back to an earlier time.
- climax — the most intense or important moment in a story.
- contribute / function / role — what a part does for the whole (paragraph 3 gives an example).
The four big structures and their signal words
In plain words: most texts follow one of four plans. Small "signal words" tell you which one.
Most nonfiction on the GED uses one main structure. Sometimes it has a smaller one inside it. Learn each one with its "tell-tale" words.
| Structure | What the author is doing | Signal words | Typical text |
|---|---|---|---|
| Sequence / chronological | Telling steps or events in order | first, next, then, after, later, finally, in 1990, by noon | instructions, history, biography, stories |
| Compare-contrast | Showing likenesses and differences | both, similarly, also, like / however, but, unlike, by contrast, on the other hand, differ | product or plan comparisons, two viewpoints |
| Cause-effect | Explaining why and what happens | because, since, so, therefore, as a result, consequently, led to, due to | science articles, history, reports |
| Problem-solution | Naming a problem, then fixes | problem, issue, challenge / solution, one answer, to fix, strategy, proposal | editorials, proposals, community articles |
Look at the figure:
Example. Read these sentences: "Many renters cannot install solar panels. One answer is a community solar garden." The word cannot signals a problem. One answer signals a solution. So this is problem-solution.
Structures can nest, like boxes inside a bigger box. A problem-solution article often explains the causes of the problem first (cause-effect). Then it offers solutions. When a question asks about the overall structure, choose the big pattern that covers the whole text. When it asks about one paragraph, choose the pattern of that paragraph.
How a part contributes to the whole
In plain words: every paragraph is there for a reason. Your job is to name that reason.
The most common GED structure question asks what one part does. Think of a text like a team: every player has a job. Here are the jobs you will see most often:
- Introduces the topic, problem or main claim (often paragraph 1).
- Provides background — history or context the reader needs.
- Gives an example — makes a general idea concrete, often with one person or case ("Consider...", "For example...").
- Explains causes or effects.
- Presents a solution or proposal.
- Adds a limitation or counterpoint — "However, these solutions are not perfect."
- Restates or clarifies — "In other words..."
- Concludes — sums up, calls readers to action, or looks to the future.
Method: label as you read. Give each paragraph a two- or three-word label, in your head or on your noteboard. Examples: problem, causes, example, fix, limits, wrap-up. When a question asks about paragraph 4, you already know its job.
Example. An article about food deserts has this paragraph 3: "Take Ruth Dawson, 71, who rides two buses to buy fresh vegetables." Paragraphs 1 and 2 explained food deserts in general. Paragraph 3's job: give a specific example of how the problem affects a person.
Sentence-level questions work the same way. Ask: What would be lost if this sentence were deleted?
Structure in workplace documents
In plain words: work documents put the most important thing first, so busy people can act fast.
The GED often uses memos, emails, policies and instructions. These texts are organized so busy readers can act quickly. Common patterns:
- Purpose first. The first paragraph says what the document is about and why it matters ("Open enrollment runs from October 15...").
- Similarities, then differences. A comparison of two options may first cover what is the same. Then readers can focus on what is different.
- Numbered or sequenced steps. "First, log in... Next, review... Finally, save."
- Headings such as Eligibility, Amount, How to Apply. Each heading is a clue to the section's role.
- Closing action. Contact information, deadlines, or a reminder to act.
Example. A safety notice reads: "(1) Starting May 1, all forklift drivers must complete a refresher course. (2) Last year, the warehouse had six forklift accidents, three of them involving new hires. (3) To register, sign up at the front desk by April 20." Paragraph 1 states the new rule. Paragraph 2 explains why (the cause). Paragraph 3 gives the steps to follow.
Structure in literary texts
In plain words: stories are built in an order, too — and sometimes they jump back in time.
Stories have structure too. The GED may ask how a scene, paragraph or detail fits into a story.
- Chronological plot: exposition (setting and characters) → rising action → climax → falling action → resolution.
- Flashback: the story jumps to an earlier time, then returns. Look for triggers that start it (a smell, a photo, a song). Look for exit signals that end it (a sudden noise, a character blinking or looking up).
- Foreshadowing: an early detail hints at something later.
- Placement of key details: authors often save the most emotional discovery for the end. By then, the character's thoughts have prepared the reader.
- Short paragraphs often mark a turning point (a shift in time, place or mood).
Worked example 1: Overall structure
(1) Every spring, the Millbrook River floods low-lying streets. (2) The flooding happens because new parking lots and roads have replaced fields that once soaked up rainwater. (3) To reduce flooding, the town plans to build a rain garden along Front Street and to require new parking lots to use pavement that lets water drain through.
Question: Which best describes the structure of the passage? A. a comparison of two rivers B. a sequence of historical events C. a problem, its cause, and proposed solutions D. an argument followed by a rebuttal
Think-aloud:
- Label each sentence. Sentence 1: problem (floods). Sentence 2: "happens because" → cause. Sentence 3: "To reduce flooding, the town plans" → solutions.
- My labels read: problem, cause, solution. That matches C.
- Eliminate: only one river (not A); no dates or events in order (not B); no opposing side is answered (not D).
Answer: C.
Worked example 2: Role of a paragraph
(1) Online banking has made it easier than ever to pay bills. (2) Scammers have noticed. Last year, Americans reported losing millions of dollars to fake bank texts. (3) Consider Ray, a retired mechanic. He received a text that looked like it came from his bank and asked him to "confirm" his password. He did, and his account was emptied within an hour. (4) To protect yourself, never click links in unexpected texts, and call your bank using the number on the back of your card.
Question: How does paragraph 3 contribute to the passage?
Think-aloud:
- Before paragraph 3, the author talks about scams in general (millions of dollars lost).
- Paragraph 3 starts with "Consider Ray," a signal for an example. It shows exactly how one scam works on one person.
- Paragraph 4 gives the solution (advice).
- So paragraph 3's job: it gives a specific example. The example makes the general danger feel real. It also shows why the advice in paragraph 4 matters.
- Wrong answers to expect: "It offers advice" (that's paragraph 4), "It explains why banks went online" (not in the text), "It argues that online banking should end" (the author never says that).
Answer: It provides a concrete example of how a text-message scam harms a real person.
Worked example 3: Signal words
Electric cars cost more to buy than gasoline cars. However, they usually cost less to fuel and maintain. Over ten years, many owners spend about the same or less in total.
Question: The word "However" signals that the second sentence A. gives an example of the first sentence B. presents a contrasting point C. states the cause of the first sentence D. lists the next step in a process
Think-aloud:
- However belongs to the contrast family (but, however, on the other hand).
- Check the meaning: sentence 1 says electric cars cost more to buy; sentence 2 says they cost less to run. The ideas point in opposite directions, so this is a contrast.
- Eliminate: no example (A), no "because" relationship (C), no steps (D).
Answer: B.
Worked example 4: A detail's place in a story
(1) Grace had driven past the old ballfield a thousand times without stopping. (2) Today she pulled over. The bleachers were rusted, and weeds grew through home plate. (3) She remembered her father crouched behind that plate, calling, "Eye on the ball, Gracie!" every Saturday for six summers. (4) She walked to the fence and found, still scratched into the paint, two sets of initials: G.M. and Dad.
Question: Why does the author place the detail about the initials at the end of the passage?
Think-aloud:
- Structure check: sentences 1-2 are the present; sentence 3 is a memory (flashback); sentence 4 returns to the present.
- The memory tells us how close Grace and her father were. Then the initials appear as physical proof that the past was real.
- Saving the initials for the end gives the passage its emotional high point. If they came first, they would not mean much, because we would not yet know about the Saturdays.
- Wrong answers to watch for: "to show the ballfield needs repairs" (a detail, not the purpose), "to introduce a conflict" (nothing is in conflict).
Answer: To create an emotional climax: after the memory, the initials show that the bond with her father is still present in the place.
Common traps
- Mixing up the part and the whole. Wrong: "The passage is organized as an example," because paragraph 3 is an example. Right: Overall structure must cover every paragraph; paragraph 3 is only one part.
- Trusting one signal word too much. Wrong: "I saw first, so the whole passage is sequence." Right: First may only introduce the first of several reasons. Check the meaning around the signal word.
- Choosing a job that belongs to a different paragraph. Wrong answers often describe a real paragraph, just not the one asked about. Right: Go back and reread the exact paragraph number in the question.
- Mixing up cause-effect and sequence. Wrong: "Then the river flooded" means cause. Right: Then only shows time. Cause needs a reason: because, so, as a result.
- Reading too much into a story detail. Wrong: In a moving-day story, a car horn pulls a character out of a memory, so "the horn means a fight with the movers is coming." Right: Stick to what the text shows. A sound often just ends a flashback.
- Picking the answer that sounds most impressive. The right answer is the one you can prove with words in the passage. It is not the one with the fanciest vocabulary.
Test-day strategy
- Read the question stem first so you know whether it asks about the whole passage, one paragraph or one sentence.
- Label each paragraph with a two- or three-word job as you read. This takes seconds and answers most structure questions.
- Find the topic sentence. The first sentence of a paragraph usually announces its role ("The causes are...", "One solution is...").
- Circle signal words mentally and sort them into families: sequence, contrast, cause-effect, example, restatement.
- Use the "delete test" for sentence questions: what would the reader lose if the sentence disappeared?
- Eliminate answers that describe a different paragraph. This is the most common trap on structure questions.
- For drag-and-drop tables, place the tiles you are sure of first; the leftovers become easier.
- Watch the clock. Labeled paragraphs make structure questions some of the fastest on the test.

Cooling Down the Hottest Blocks
(1) On a July afternoon in many American cities, the temperature on one block can be ten degrees higher than the temperature a mile away. Scientists call this the urban heat island effect. It is not just uncomfortable. Extreme heat sends thousands of people to emergency rooms each summer, and it is especially dangerous for older adults, outdoor workers, and people who cannot afford air conditioning.
(2) The causes are mostly built into the city itself. Dark asphalt and rooftops absorb sunlight during the day and release that heat slowly at night, so neighborhoods never fully cool off. Cars, air conditioners, and factories add even more heat. Meanwhile, blocks with few trees lose the natural cooling that shade and leaves provide. As a result, the hottest neighborhoods are often the ones with the most pavement and the least green space.
(3) Consider the experience of Marisol Vega, a home health aide in the fictional city of Eastport. She walks between her clients' apartments all day. "By noon, the sidewalk feels like a stove," she says. On her route, there is almost no shade for six blocks. She now carries two bottles of water and plans her visits so that she is indoors during the hottest hours.
(4) Cities have begun to fight back with several strategies. The first is planting trees. A mature street tree can shade a sidewalk and cool the air around it as water evaporates from its leaves. A second strategy is "cool roofs," which are painted white or coated with reflective material so they bounce sunlight away instead of absorbing it. A third is replacing some asphalt with lighter pavement or with grass and plants.
(5) None of these solutions is instant. A young tree may need fifteen years to grow a wide canopy, and it needs watering and care in its first few summers. Cool roofs cost money, although they can lower a building's cooling bills. For these reasons, some planners argue that cities should start with the blocks that are hottest and have the most vulnerable residents.
(6) The heat island problem took decades of building to create, and it will take years to undo. But each shaded sidewalk and each reflective roof makes a measurable difference for the people who live and work below.
Which statement best describes the overall structure of the passage?
Hint
Look at what each paragraph does in order: first what is wrong, then why, then what is being done about it.
Step-by-step solution
Trace the job of each paragraph. Paragraph 1 names a problem: "Scientists call this the urban heat island effect" and explains that extreme heat "sends thousands of people to emergency rooms." Paragraph 2 gives the causes: "The causes are mostly built into the city itself." Paragraph 3 shows how the problem affects one worker. Paragraph 4 turns to solutions: "Cities have begun to fight back with several strategies." Paragraph 5 notes limits of those solutions, and paragraph 6 wraps up.
So the passage describes a problem, explains why it happens, and then presents ways to solve it. That is a problem-solution structure (with a cause-effect section inside it).
The correct answer is A.
The other choices name real structures, but not this one. Only one city (a fictional one) is described, so it is not a comparison of cities. There are no dates moving forward in order, so it is not a history. And the author never sets up an opinion just to argue against it.
Tip: For "overall structure" questions, write a two- or three-word label beside each paragraph (problem, causes, example, solutions). The pattern in your labels is the answer.

How does paragraph 3 contribute to the passage?
Hint
Paragraph 3 is about one person. Why would an author put one person's story right after a list of causes?
Step-by-step solution
Paragraph 3 focuses on a single person: "Consider the experience of Marisol Vega, a home health aide." It describes her day ("By noon, the sidewalk feels like a stove") and how she has changed her habits ("She now carries two bottles of water").
Paragraphs 1 and 2 explain the heat island effect in general terms (temperatures, asphalt, rooftops). Paragraph 3 makes those general facts concrete by showing how the heat affects a real working person. The phrase "Consider the experience of" is a classic signal that an example is coming.
The correct answer is B.
Why not the others? The solutions (trees, cool roofs, lighter pavement) do not appear until paragraph 4. The scientific causes are explained in paragraph 2, not 3. And Marisol's story supports the author's point that heat is dangerous; it does not argue against it.
Tip: When a paragraph tells one person's story inside an informational text, its usual job is to give a concrete example of the general idea that came just before it.
Summary
- Text structure is how an author organizes ideas: sequence, compare-contrast, cause-effect, problem-solution (and flashback in stories).
- Signal words reveal the structure: first/then (sequence), however/by contrast (contrast), because/as a result (cause-effect), one solution (problem-solution).
- To explain how a part contributes, name its job. Jobs include: introduce, give background, give an example, explain causes, propose solutions, add limits, conclude.
- Overall-structure answers must cover the whole text; paragraph answers must match that exact paragraph.
- In stories, watch for flashbacks, turning points and key details saved for the end.
- Label paragraphs as you read; it is the fastest route to the right answer.
