Analyze Source Arguments — Analyze reasoning and credibility in source texts.

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.

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.

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.

Visual Explanation — Anatomy of an Argument

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.

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.

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).

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.

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).

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.

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.

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.

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.

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.
