Analyze Source Arguments — Analyze reasoning and credibility in source texts. - GED Reasoning Through Language Arts

SECTION 1

Historical Context & Motivation

The ability to analyze arguments is one of the oldest intellectual skills in human history. Ancient Greek philosophers recognized that not every statement deserves equal trust, and they developed formal systems to distinguish sound reasoning from faulty logic. Rhetoric — the art of persuasion — became a core subject in classical education, and students were expected to both construct and critique arguments as part of civic life. Today, the GED Extended Response tasks carry that tradition forward by asking you to read two source texts and evaluate the strength of each author's position.

~350 BCE • Aristotle's Rhetoric

Aristotle identified three pillars of persuasion — ethos (credibility), pathos (emotion), and logos (logic) — creating the first systematic framework for analyzing arguments.

1690 • Locke's Essay Concerning Human Understanding

John Locke emphasized that claims must be supported by observable evidence rather than authority alone, laying groundwork for modern critical thinking.

1941 • Propaganda Analysis Movement

During World War II, educators in the United States developed curriculum to help citizens recognize propaganda techniques and biased reasoning in media.

2014 • GED Extended Response Introduced

The redesigned GED test added the Extended Response, requiring test-takers to analyze paired source texts and evaluate which author presents the stronger argument supported by evidence.

In our current information-rich environment, the question is no longer whether you can find an argument — it's whether you can tell a strong argument from a weak one. On the GED Extended Response, you'll be given two texts on the same issue and asked to determine which author builds a more convincing case. This lesson will equip you with the analytical tools to do exactly that — and show you how to express your analysis in a well-organized written response.

SECTION 2

Core Principles of Argument Analysis

Before you can evaluate a source argument, you need to understand the building blocks that make up any argument. Every argument consists of a claim (the main point the author wants you to accept), evidence (the facts, examples, or data used to support the claim), and reasoning (the logical connection between the evidence and the claim). When any of these elements is missing or weak, the argument loses its persuasive power.

Claim

The author's main assertion or position on the issue. A strong claim is specific, debatable, and clearly stated. Look for it in the introduction or conclusion of the text.

Evidence

The supporting material — statistics, expert opinions, historical examples, case studies, or personal anecdotes. Strong evidence is relevant, specific, and comes from credible sources.

Reasoning

The logical bridge connecting evidence to the claim. Good reasoning shows clearly how the evidence proves the point. Watch for logical fallacies that break this bridge.

Credibility

The trustworthiness of the author and sources cited. Credibility depends on expertise, objectivity, and the quality of evidence. Biased or unqualified sources weaken the argument.

Counterarguments

Acknowledgment of opposing views. Strong arguments address counterarguments directly and explain why their own position is still stronger, rather than ignoring the other side entirely.

✦

KEY TAKEAWAY

Think of an argument like a bridge. The claim is one side of the river, and the reader's agreement is the other side. Evidence provides the steel beams, and reasoning is the engineering that holds those beams together. If the steel is flimsy (weak evidence) or the engineering is sloppy (faulty logic), the bridge collapses — and the reader never crosses over to agree.

SECTION 3

Visual Explanation — Anatomy of an Argument

This diagram shows how a well-constructed argument flows from a central claim through multiple pieces of evidence, each connected by clear reasoning to a persuasive conclusion. When you analyze a source text, trace this flow and look for any missing or weak connections.

When reading a source text on the GED, your first task is to identify the author's claim. This is usually stated explicitly in the opening or closing paragraph. Next, scan for evidence — look for numbers, named experts, historical events, or real-world examples. Finally, examine how the author connects each piece of evidence back to the claim. If the author simply lists facts without explaining their relevance, the reasoning is weak even if the evidence itself is solid.

SECTION 4

How Argument Analysis Works — The Evaluation Framework

The GED Extended Response: Format and Scoring

Before learning how to analyze source arguments, it helps to understand exactly what the GED Extended Response asks you to do — and how your response will be graded. The Extended Response is a 45-minute, computer-based writing task. You will type your response into a text box on screen. You are given two source texts on a debatable issue and asked to write a response of approximately 4–7 paragraphs explaining which author makes the stronger argument. Your response must use evidence drawn from the source texts themselves — not from your personal knowledge or outside experience. This task directly mirrors the reading and writing skills targeted by the GED Reasoning Through Language Arts test: closely reading informational texts, comparing the quality of evidence and reasoning across two passages, and producing a well-organized, evidence-based written analysis.

ℹ

OFFICIAL GED SCORING TRAITS

Your Extended Response is scored on three official scoring traits defined by GED Testing Service: Trait 1 — Creation of Arguments and Use of Evidence (0–2 points): Does your response identify which argument is stronger and support that judgment with specific evidence from the texts? Trait 2 — Development of Ideas and Organizational Structure (0–2 points): Is your response clearly organized, with a logical flow from introduction through body paragraphs to conclusion? Do your ideas develop and connect smoothly? Trait 3 — Clarity and Command of Standard English Conventions (0–2 points): Is your writing clear, with correct grammar, punctuation, spelling, and sentence structure? The maximum raw score is 6 points. Understanding these traits helps you focus your writing on what scorers actually look for.

A Reading and Analysis Process for the Extended Response

Because you have only 45 minutes, you need an efficient, repeatable process for moving from reading the source texts to writing your response. The steps below give you a practical approach that maps directly onto the three scoring traits: first understand the arguments (Trait 1), then plan your structure (Trait 2), then write carefully (Trait 3).

Step 1 — Read Actively (~8 min)

Read each source text and identify the main claim. On your second pass, note the evidence and how it connects to the claim. Use the on-screen highlighting or take scratch notes.

Step 2 — Annotate the Elements (~5 min)

Label each part: Claims, Evidence, and Reasoning. Note any logical fallacies or emotional appeals. Jot down which text uses stronger, more credible evidence.

Step 3 — Compare the Sources (~5 min)

Place the two arguments side by side in your notes. Which uses more specific evidence from the texts? Which addresses counterarguments? Decide which is the stronger argument.

Step 4 — Write Your Response (~25 min)

Write 4–7 paragraphs: an introduction stating your thesis, body paragraphs that use evidence from the texts to support each point, and a conclusion. Stay grounded in the texts — avoid inserting outside knowledge.

Credibility Checklist

Credibility is not just about whether you like the author's position — it's about whether the author has earned your trust through the quality of their argument. When evaluating source credibility, ask yourself four key questions: Does the author cite verifiable sources? Does the author have relevant expertise or authority? Is the tone fair and balanced rather than purely emotional? Does the author acknowledge the other side of the debate? An author who checks all four boxes is more credible than one who relies solely on personal opinion or emotional language.

💡

GED TEST TIP

On the GED Extended Response, you are not being asked for your personal opinion on the issue. You are being asked to analyze which author builds a stronger argument using evidence from the texts. Focus on the quality of reasoning and evidence in the passages, not on whether you agree or disagree with the position — and never bring in facts or examples from outside the source texts.

SECTION 5

Common Logical Fallacies & Evidence Quality

One of the most powerful ways to evaluate a source argument is to identify logical fallacies — errors in reasoning that make an argument seem convincing on the surface but actually weaken it when you look more closely. Recognizing these fallacies is a critical skill for the GED Extended Response because it allows you to pinpoint exactly where an author's reasoning breaks down, which directly supports Trait 1 scoring (Creation of Arguments and Use of Evidence).

This diagram illustrates six common logical fallacies you may encounter in source texts, along with an evidence quality spectrum ranging from weak (personal opinion) to strong (data and studies). Use these as a checklist when evaluating GED source passages.

Keep in mind that the presence of emotional language does not automatically make an argument weak. Skilled authors often combine emotional appeals with solid evidence and logical reasoning. The problem arises when emotion is the only tool the author uses, substituting feelings for facts. Similarly, anecdotes can be powerful illustrations when paired with broader data, but they are insufficient as standalone evidence because a single story cannot prove a general trend.

SECTION 6

Worked Example — Evaluating Paired Source Texts

Let's walk through a realistic GED-style analysis. Imagine you've read two short passages about whether schools should require students to wear uniforms. Author A argues in favor; Author B argues against. On the actual GED, you would read the full texts on screen, then type your response in 45 minutes. Here we focus on the analysis process that drives strong Trait 1 scoring.

ℹ

PASSAGE SUMMARIES

Author A claims that school uniforms reduce bullying and increase academic focus. Author A cites a 2015 study from the National Center for Education Statistics showing a 12% decrease in behavioral incidents at uniform-requiring schools. Author A also quotes a school principal who reports improved classroom behavior. Author B claims that school uniforms violate students' freedom of expression and are an unnecessary expense for families. Author B shares a personal story about a student who felt "stifled" by uniform requirements and describes uniforms as "an outdated relic of authoritarian thinking."

Analyzing Which Author Has the Stronger Argument

1
Step 1 — Identify Each Author's Claim

Author A claims that school uniforms benefit students by reducing bullying and improving academic focus. Author B claims that school uniforms harm students by limiting self-expression and burdening families financially. Both claims are clearly stated and debatable, which is a good starting point.

Both claims are clear and specific.
2
Step 2 — Evaluate the Evidence

Author A provides a specific statistic from a named, credible source (the National Center for Education Statistics) and includes an expert quote from a school principal. This evidence is verifiable and relevant. Author B, on the other hand, relies on a single personal anecdote about one student's experience. While this story is emotionally compelling, it represents only one person's perspective and cannot prove a broader trend.

Author A's evidence is stronger — it is specific, data-driven, and from a credible source.
3
Step 3 — Assess the Reasoning

Author A draws a logical connection: if a national study shows fewer behavioral incidents at schools with uniforms, then uniforms likely contribute to a more focused learning environment. This reasoning follows logically from the evidence. Author B's reasoning contains a fallacy — calling uniforms "an outdated relic of authoritarian thinking" is loaded language that appeals to emotion rather than providing a logical argument. Author B does not explain how uniforms specifically limit expression in a way that harms students.

Author A's reasoning is more logically sound; Author B relies on emotional language.
4
Step 4 — Check for Counterarguments

Author A briefly acknowledges that "some may feel uniforms limit creativity" but argues that the academic and behavioral benefits outweigh this concern. Author B does not address any of the potential benefits of uniforms. By acknowledging the opposing view, Author A demonstrates a more thorough and fair-minded approach to the issue.

Author A addresses counterarguments; Author B does not.
5
Step 5 — Form Your Evaluation and Plan Your Response

Based on this analysis, Author A presents the stronger argument. Author A's evidence is more credible (a national study vs. a single anecdote), the reasoning is more logical (data-driven conclusion vs. emotional language), and Author A demonstrates fairness by acknowledging the opposing position. In your Extended Response, you would state this conclusion in your opening paragraph as a clear thesis, develop it with text-based evidence across 3–5 body paragraphs, and close with a concise conclusion — all within the 45-minute time limit. Remember: every claim you make in your response must be supported by evidence from the source texts.

Author A has the stronger argument due to superior evidence, logical reasoning, and acknowledgment of counterarguments. This conclusion becomes your thesis for the written response.

SECTION 7

Comparing Strong and Weak Arguments

Understanding the contrast between strong and weak arguments helps you quickly evaluate source texts under the time pressure of the GED exam. The following table summarizes the key differences across the elements you've learned.

Element	Strong Argument	Weak Argument
Claim	Specific, debatable, and clearly stated	Vague, overly broad, or hidden within the text
Evidence	Data, expert citations, verifiable facts from credible sources	Anecdotes, unsupported generalizations, or no evidence at all
Reasoning	Logical connections between evidence and claim; no fallacies	Logical fallacies, leaps in logic, or evidence that doesn't support the claim
Tone	Measured, fair, and confident without being dismissive	Overly emotional, mocking, or one-sided
Counterarguments	Acknowledges opposing views and refutes them with evidence	Ignores or misrepresents opposing views entirely
Credibility	Cites reputable, relevant sources; author has expertise	Sources are unnamed, irrelevant, or absent; author lacks authority

Key differences between strong and weak arguments across six analytical elements.

✦

KEY TAKEAWAY

Think of analyzing an argument like being a judge in a courtroom. You're not deciding whether you personally believe the defendant is guilty or innocent — you're evaluating which lawyer made a stronger case based on the evidence presented. The GED Extended Response works the same way: set aside your opinion and focus on which author's "case" is better built. Then write that evaluation clearly, using evidence from the texts, in a well-organized response within your 45-minute window.

SECTION 8

Connecting to College-Level Critical Analysis

The argument analysis skills you develop for the GED are not just test strategies — they form the foundation of college-level critical thinking. In college courses, you'll be expected to evaluate sources in research papers, analyze peer-reviewed studies, and critique arguments made by established scholars. The difference is mainly one of complexity: college texts may use more sophisticated vocabulary and denser evidence, but the core process of identifying claims, evaluating evidence, and testing reasoning remains the same.

Skill Area	GED Level	College Level
Source Types	Two paired passages on a social or policy issue	Peer-reviewed journals, books, primary documents, databases
Claim Analysis	Identify the main argument and supporting points	Evaluate thesis statements, hypotheses, and implied assumptions
Evidence Evaluation	Assess relevance and credibility of cited facts and examples	Analyze methodology, sample sizes, statistical significance, and bias
Written Response	45-minute, computer-based essay (4–7 paragraphs) evaluating the stronger argument using evidence from the source texts	Research papers, literature reviews, and analytical essays with citations

How GED argument analysis skills scale to college-level expectations.

Earning your GED credential demonstrates that you have the reading, writing, and critical thinking skills needed for college and career success. If you can consistently identify logical fallacies, weigh the quality of evidence, articulate why one argument outperforms another, and express that analysis in a clear written response, you already possess the critical skills that many entering college students are still developing. These are also valuable abilities in everyday life — from evaluating news articles to making informed decisions as a consumer and citizen.

SECTION 9

Practice Problems

Question 1: CONCEPTUAL

What are the three essential components of an argument, and why is each one important? Explain in your own words.

Show answer

The three essential components are the claim, the evidence, and the reasoning. The claim is the author's main position — without it, the reader doesn't know what the author is trying to prove. The evidence provides the factual support — without it, the claim is just an opinion. The reasoning is the logical connection between the evidence and the claim — without it, even strong evidence fails to prove the point because the reader can't see how the facts relate to the argument. All three must work together for an argument to be persuasive. On the GED Extended Response, identifying these three components in each source text directly supports Trait 1 scoring: Creation of Arguments and Use of Evidence.

Question 2: BASIC CALCULATION

An author writes: "Ninety percent of dentists recommend this toothpaste, so it must be the best product available." Identify the type of evidence used and explain one weakness of this argument.

Show answer

The author uses a statistic ("ninety percent of dentists") as evidence. One weakness is that the source of this statistic is not identified — we don't know who conducted the survey, how many dentists were asked, or how "recommend" was defined. Additionally, this argument commits a logical leap: even if most dentists recommend the product, that doesn't necessarily mean it is "the best" — there could be several equally recommended brands. The claim goes beyond what the evidence actually proves.

Question 3: INTERMEDIATE

Author X argues for stricter pollution regulations by citing EPA data showing a 30% increase in respiratory illness near industrial zones over ten years. Author Y opposes stricter regulations by saying: "My grandfather worked in a factory his whole life and lived to be 95." Which author presents a stronger argument, and what specific analytical criteria support your evaluation?

Show answer

Author X presents a stronger argument based on several criteria. First, evidence quality: Author X cites EPA data — a credible, government-backed source — with a specific statistic (30% increase) over a defined time period (ten years), while Author Y relies on a single personal anecdote. Second, reasoning: Author X draws a logical connection between pollution exposure and health outcomes using population-level data, while Author Y commits the fallacy of using one individual's experience to disprove a broad trend. Third, credibility: Author X's source (the EPA) is a recognized authority on environmental health, while Author Y's evidence is purely subjective. Author Y's argument is essentially a hasty generalization — using one case to dismiss widespread data. In a GED Extended Response, you would build your thesis around this conclusion and support it with specific references to each author's evidence from the texts.

Question 4: APPLIED

You are reading an editorial that argues: "Social media is destroying teenagers' mental health. A recent survey of 500 high school students found that 65% report feeling anxious after using social media for more than two hours daily. Furthermore, psychologist Dr. Elena Martinez notes that 'the constant comparison inherent in social media platforms correlates with increased rates of depression among teens.' However, some argue that social media helps teens build communities and stay connected. While this may be true for some users, the weight of evidence suggests that the harms outweigh the benefits for most adolescents." Evaluate the strength of this argument by identifying its claim, evidence, reasoning, and how it handles counterarguments.

Show answer

Reading and analysis: The claim is that social media is harming teenagers' mental health. The evidence includes a survey with a specific sample size (500 students) and a concrete finding (65% report anxiety), plus an expert quote from Dr. Elena Martinez, a psychologist. The reasoning connects these data points to the broader claim about harm. The author also addresses a counterargument (social media helps build communities) before explaining why the overall evidence still supports the claim. Evaluation: This is a strong argument. The evidence is specific and quantified (survey data), the expert source is relevant (a psychologist specializing in mental health), and the author demonstrates intellectual honesty by acknowledging the opposing view. The argument could be stronger with peer-reviewed studies rather than just a survey, but it effectively uses multiple evidence types and addresses the other side. In a GED Extended Response, this analysis would score well on Trait 1 (identifying the argument and using text evidence), and presenting it in clearly organized paragraphs would support Trait 2 (organizational structure).

Question 5: CRITICAL THINKING

Consider a scenario where both authors in a GED passage use logical fallacies, but one also includes some strong, well-sourced evidence. How would you approach writing your Extended Response in this situation? Should you claim one argument is "perfect"? Explain your strategy and what your thesis statement might look like, keeping in mind the three official GED scoring traits.

Show answer

In this situation, you should never claim either argument is perfect — the GED scorers reward nuanced analysis under all three official scoring traits. Your strategy would be to acknowledge the weaknesses in both arguments while still determining which one is relatively stronger. Identify the specific fallacies in each text, then explain why the author who combines fallacies with strong evidence still presents a more persuasive overall case than the author who uses fallacies without credible support. A strong thesis might read: "While both authors weaken their arguments through logical fallacies, Author A presents the stronger case because their use of verifiable data and expert sources provides a foundation of credible evidence that Author B's argument lacks entirely." This approach shows that you can think critically about imperfect texts, weigh relative strengths and weaknesses, and arrive at a justified conclusion — which is exactly what Trait 1 (Creation of Arguments and Use of Evidence) rewards. Organizing this analysis into clear paragraphs with specific text references will also earn points under Trait 2 (Development of Ideas and Organizational Structure).

SUMMARY

Lesson Summary

Summary

Analyzing source arguments is the central skill tested on the GED Extended Response — a 45-minute, computer-based writing task in which you read two paired source texts and write approximately 4–7 paragraphs explaining which author makes the stronger argument. Your response must draw evidence exclusively from the source texts. It is scored on three official traits: Trait 1 — Creation of Arguments and Use of Evidence (0–2 pts), Trait 2 — Development of Ideas and Organizational Structure (0–2 pts), and Trait 3 — Clarity and Command of Standard English Conventions (0–2 pts) — for a maximum of 6 points.

Every argument in the source texts consists of three building blocks: a claim (the author's main position), evidence (the facts and data supporting that position), and reasoning (the logical connection between the evidence and the claim). To evaluate which author builds the stronger case, read each text actively, annotate the argument elements, compare the two sources, and then write your response. Pay close attention to credibility — look for named, reputable sources and expert authority — and watch for logical fallacies such as ad hominem attacks, straw man distortions, false dilemmas, appeals to emotion, bandwagon reasoning, and slippery slopes.

The GED does not ask for your personal opinion on the issue — it asks you to objectively assess which author's argument is better constructed, using only evidence from the texts. Strong arguments use specific, verifiable evidence, connect that evidence to the claim through sound reasoning, and demonstrate fairness by acknowledging counterarguments. These analytical and writing skills extend far beyond the test — they are the foundation of college-level critical thinking, informed decision-making, and effective communication in any field.
