Identify Method Of Reasoning — Describe the method of...

SECTION 1

Historical Context & Motivation

The ability to identify how an argument is constructed—rather than merely evaluating whether its conclusion is true—has deep roots in the history of logic and rhetoric. From Aristotle's systematic categorization of syllogistic reasoning in the Organon to the modern analytical philosophy tradition's emphasis on argument mapping, scholars have long recognized that understanding the method of reasoning is a prerequisite for evaluating its soundness. The GMAT's Critical Reasoning section inherits this tradition by requiring test-takers to do more than simply agree or disagree with a conclusion; instead, candidates must articulate the structural strategy an argument employs—an exercise that mirrors the kind of analytical thinking expected in graduate business programs. The introduction of boldface questions on the GMAT elevated this skill further by isolating specific sentences within an argument and asking test-takers to describe their structural roles.

~350 BCE

Aristotle's Syllogistic Logic

Aristotle formalized the study of argument structure by categorizing valid reasoning patterns—premises, conclusions, and their logical relationships—establishing the foundation for all future argument analysis.

1958

Toulmin's Argumentation Model

Stephen Toulmin published a model of practical reasoning that distinguished claims, grounds, warrants, and backing—a framework that mirrors how GMAT arguments decompose into premises, assumptions, and conclusions.

1994

GMAT Introduces Critical Reasoning

The Graduate Management Admission Council (GMAC) formalized the Critical Reasoning question type, requiring candidates to analyze argument structure, identify assumptions, and evaluate logical strategies.

~2005

Boldface Questions Appear

GMAC introduced boldface-style questions that highlight specific sentences in an argument and ask test-takers to describe the role each bolded statement plays, raising the bar for structural analysis.

2023

GMAT Focus Edition

The updated GMAT Focus Edition retains Critical Reasoning in its Verbal Reasoning section, confirming that method-of-reasoning and boldface questions remain core competencies for graduate admission.

The central question these developments address is deceptively simple: How does an argument attempt to persuade? Answering this question requires you to step outside the content of the argument and view its architecture from above—recognizing which statements serve as evidence, which function as intermediate conclusions, and which represent the author's main point. Boldface questions take this one step further by pinpointing specific structural elements and demanding precise labels for each.

SECTION 2

Core Principles & Definitions

Before dissecting any method-of-reasoning question, you must internalize the vocabulary of argument structure. Every Critical Reasoning stimulus contains an argument—a set of statements in which some statements (premises) are offered in support of another statement (the conclusion). Between the premises and the conclusion, there may be intermediate conclusions, background context, counterarguments, and concessions. Mastery of these structural roles is the foundation upon which all method-of-reasoning analysis rests.

Premise

A statement offered as evidence or a reason to believe the conclusion. Premises are the building blocks of support; they are presented as given or established facts, data, observations, or principles.

Conclusion

The claim the argument is trying to establish. The conclusion is the statement that the premises collectively support. It may be the main conclusion or an intermediate conclusion that feeds into the main one.

Intermediate Conclusion

A statement that is both supported by premises and used as support for the main conclusion. It functions as a logical stepping stone, bridging evidence and the argument's ultimate claim.

Counter-Premise / Objection

A statement that opposes or complicates the argument's conclusion. Authors often introduce counter-premises to acknowledge opposing viewpoints before refuting them, thereby strengthening their position.

Background / Context

Information that sets the scene but does not directly function as evidence for or against the conclusion. Background statements provide necessary context—definitions, historical facts, or situational details—without performing a logical role.

Method-of-reasoning questions on the GMAT come in two distinct formats. The first is the general method-of-reasoning format, in which the question stem asks you to describe the overall argumentative strategy—for example, "The argument proceeds by" or "Which of the following best describes the method of reasoning used in the argument?" The second is the boldface format, in which one or two statements in the stimulus are printed in boldface and the question asks you to identify the role that each bolded statement plays within the argument's structure. Boldface questions are generally considered more challenging because they require precise labeling of individual components rather than a holistic description.

✦ KEY TAKEAWAY

Think of an argument like a building's blueprint. The conclusion is the roof—the thing the entire structure is meant to support. Premises are the load-bearing walls. Intermediate conclusions are the floors between stories, simultaneously resting on walls below and supporting the roof above. Background is the landscape around the building—it tells you where the building sits but doesn't hold anything up. A counter-premise is like an inspector's objection: acknowledging it and then resolving it is part of proving the building is sound. Method-of-reasoning questions ask you to describe the blueprint; boldface questions point to specific beams and ask, "What does this piece do?"

SECTION 3

Visual Explanation: Argument Anatomy

The diagram below maps the anatomy of a typical GMAT argument that might appear in a boldface question. It shows how background context, premises, counter-premises, intermediate conclusions, and the main conclusion relate to one another in a hierarchical flow. Understanding this visual structure is essential for quickly categorizing each bolded statement.

This diagram illustrates the hierarchical relationships among argument components. Blue boxes represent premises (evidence), the violet box represents an intermediate conclusion (a claim supported by premises and supporting the main conclusion), the pink box is a counter-premise, the amber box is background context, and the green box is the main conclusion. Boldface questions ask you to assign each bolded statement to one of these roles.

Notice that the diagram places the main conclusion at the bottom of the support chain—everything above it feeds into it. When you encounter a boldface question, your first task is to identify the main conclusion of the argument, even if it is not one of the bolded statements. Once the main conclusion is located, you can classify every other statement relative to it: does this statement support the main conclusion directly (premise), support it indirectly (intermediate conclusion), oppose it (counter-premise), or merely set the stage (background)?

SECTION 4

How Method-of-Reasoning Questions Work

Recognizing the Question Stem

The first step in any Critical Reasoning question is reading the question stem before engaging with the stimulus. Method-of-reasoning questions use distinctive phrasing that sets them apart from strengthen, weaken, or assumption questions. General method-of-reasoning stems include variants such as "The argument proceeds by," "Which of the following describes the technique of reasoning used above?" or "The argument does which of the following?" Boldface stems typically state: "In the argument given, the two boldface portions play which of the following roles?" or "The first boldface statement plays which of the following roles in the argument?" Recognizing these stems immediately tells you that your job is descriptive—you must characterize the argument's structure, not evaluate its truth.

The Four-Step Approach

A systematic approach reduces the risk of falling for trap answer choices. The following four-step framework is designed for both general method-of-reasoning and boldface variants.

Identify the Main Conclusion

Read the entire stimulus and determine the author's ultimate claim. Look for conclusion indicator words—therefore, thus, consequently, it follows that, hence—and opinion language. The main conclusion is the statement that nothing else in the argument supports.

Map the Premises

Identify the evidence offered in support of the conclusion. Premises often follow words like because, since, given that, or after all. Ask: which statements are presented as established facts or data points?

Label Each Boldface Statement

For boldface questions, assign a structural role to each bolded sentence: premise, counter-premise, intermediate conclusion, main conclusion, or background. Check whether the bolded statement supports or opposes the main conclusion.

Match to Answer Choices

Evaluate each answer choice against your structural labels. Eliminate any choice that misidentifies even one boldface role. For general method questions, match the described strategy to the argument's actual logical technique.

Common Reasoning Methods on the GMAT

General method-of-reasoning questions require you to name the argumentative strategy. The most frequently tested methods include: analogy (arguing that because two situations share key features, what holds for one holds for the other), counterexample (refuting a general claim by presenting a specific case that contradicts it), elimination of alternatives (showing that competing explanations fail, leaving only the author's position), and reductio ad absurdum (demonstrating that an opposing position leads to an absurd or contradictory outcome). Familiarity with these patterns allows you to quickly match the argument's strategy to the correct answer choice without getting lost in content-level details.

SECTION 5

Boldface Role Classification

Boldface questions demand precise classification, and the GMAT uses a relatively predictable set of role descriptions in its answer choices. The table below catalogs the most common boldface role labels, their definitions, and the signal clues you can use to identify them within a stimulus. Mastering this taxonomy ensures that you can quickly match bolded statements to their correct structural descriptions.

This decision tree walks you through the classification process for any bolded statement. Begin by determining whether the statement is a claim (an assertion) or evidence (a factual observation). If it is a claim, determine whether it belongs to the author or to an opponent. If it is the author's claim, determine whether it is the main conclusion or merely an intermediate conclusion. The bottom panel lists common GMAT answer-choice phrasings you will encounter.

Common boldface role classifications and their identification cues

Boldface Role	Definition	Signal Clues
Main Conclusion	The ultimate claim the argument aims to establish; no other statement in the argument supports something beyond it.	Therefore, thus, hence, consequently; often the final sentence or preceded by supporting evidence.
Intermediate Conclusion	A claim that is supported by premises and itself provides support for the main conclusion.	Appears between evidence and the main conclusion; may be preceded by "so" or "this means" and followed by further reasoning.
Premise (Evidence)	A factual claim, statistic, observation, or principle offered as a reason to believe the conclusion.	Because, since, given that, after all; data points, study results, or established facts.
Counter-Premise / Opposing Position	A claim or piece of evidence that opposes the argument's conclusion; the author typically introduces it to refute it.	Some argue, it has been claimed, opponents contend; often followed by "however" or "but" as the author pivots to rebut.
Background / Context	Contextual information that sets the scene without directly serving as evidence for or against the conclusion.	Opening sentences providing definitions, historical facts, or situational framing that do not drive the logical chain.

SECTION 6

Worked Example

The following worked example demonstrates how to apply the four-step framework to a GMAT-style boldface question. Read the stimulus carefully, then follow each step.

📝 STIMULUS

Some economists have argued that raising the minimum wage invariably leads to higher unemployment among low-skilled workers. However, a recent study of 15 metropolitan areas that implemented significant wage increases found that employment levels among low-skilled workers remained stable or even increased over the subsequent three years. This result suggests that factors such as increased consumer spending and reduced employee turnover can offset the higher labor costs. Therefore, the claim that higher minimum wages necessarily reduce employment is overly simplistic.

❓ QUESTION STEM

In the argument above, the two boldface portions play which of the following roles?

Step-by-Step Solution

Step 1 — Identify the Main ConclusionThe word "Therefore" in the final sentence is a strong conclusion indicator. The main conclusion is: "the claim that higher minimum wages necessarily reduce employment is overly simplistic." This is the second bolded statement. The argument's ultimate goal is to discredit the opposing view.

Second boldface = Main Conclusion

Step 2 — Map the PremisesThe study of 15 metropolitan areas is the primary evidence. It provides data showing that employment remained stable or increased after wage hikes. The sentence about increased consumer spending and reduced turnover is an intermediate explanation that connects the study data to the main conclusion. Both of these unbolded statements serve as premises supporting the main conclusion.

Study data and economic explanation = Premises

Step 3 — Label Each Boldface StatementThe first bolded statement—"raising the minimum wage invariably leads to higher unemployment among low-skilled workers"—is attributed to "some economists" and the argument proceeds to challenge it. This is the position the author opposes: a counter-premise or opposing position. The second bolded statement, as identified in Step 1, is the main conclusion of the argument.

First boldface = Position the argument opposes (counter-premise)

Step 4 — Match to Answer ChoicesWe need an answer choice that describes the first boldface as a position the argument challenges and the second boldface as the conclusion the argument draws. The correct answer would read something like: "The first is a position that the argument challenges; the second is the main conclusion of the argument." Any answer that calls the first boldface a premise supporting the conclusion, or that calls the second boldface an intermediate conclusion, would be incorrect.

Correct: First = opposing position; Second = main conclusion

⚠️ COMMON TRAP

A frequent wrong answer on boldface questions reverses the roles—calling the opposing position the author's conclusion and vice versa. Always verify whose view each bolded statement represents. Attribution language ("some argue," "critics contend," "proponents claim") is your most reliable signal. Another trap describes one boldface statement with a role that is approximately correct but mischaracterizes its relationship to the other boldface statement.

SECTION 7

Common Traps & Elimination Strategies

Method-of-reasoning questions—particularly boldface variants—are notorious for answer choices that sound plausible but contain subtle mischaracterizations. Understanding the most common trap patterns accelerates your elimination process and prevents costly errors under time pressure. The table below contrasts effective strategies with the pitfalls they address.

Common trap answer types and how to eliminate them

Trap Type	How It Misleads	Elimination Strategy
Role Reversal	Swaps the roles of two boldface portions—e.g., calling the premise a conclusion and the conclusion a premise.	Check each half of the answer independently. If even one half is wrong, the entire answer is wrong.
Wrong Author	Attributes a boldface statement to the argument's author when it actually represents an opponent's position, or vice versa.	Pay close attention to attribution language: "some believe," "critics argue," versus unattributed assertions which belong to the author.
Scope Shift	Describes the boldface statement's content accurately but misidentifies its structural function—e.g., calling a premise "the main conclusion" because it sounds important.	Always ask: "Does any other statement in the argument support this one?" If yes, it may be a conclusion. If it supports another statement, it is a premise.
Intermediate vs. Main Confusion	Labels an intermediate conclusion as the main conclusion. Intermediate conclusions are supported by premises AND support the main conclusion.	Trace the support chain: does the bolded claim feed into a further, broader claim? If so, it is intermediate, not main.
Method Mislabel	In general method-of-reasoning questions, describes a strategy the argument does not actually use—e.g., saying it uses analogy when it actually uses counterexample.	Before looking at answers, write a brief mental summary of the argument's strategy in your own words; then find the answer that matches.

✦ KEY TAKEAWAY

Think of trap answer choices like decoys in a lineup: they share surface-level features with the correct answer but differ in one crucial detail. Your job is not to find the answer that "sounds right" in isolation—it is to find the one that accurately describes both boldface roles (or the overall method) with zero mischaracterizations. Eliminating answers with even a single incorrect element is faster and more reliable than trying to confirm the correct answer directly.

SECTION 8

Connection to Advanced Argument Structures

While most method-of-reasoning and boldface questions test straightforward argument structures, the most challenging variants introduce layered arguments—arguments within arguments, multiple competing positions, or complex evidential chains. Recognizing these advanced patterns is what separates 700+ scorers from the rest of the field. In these complex stimuli, you may encounter arguments where the author responds to an objection to a response to an original position, creating a three-tier structure that requires careful tracking of who said what and why.

Standard vs. Advanced boldface question characteristics

Feature	Standard Boldface Question	Advanced Boldface Question
Number of positions	One author + one opposing view	Two or more distinct positions, possibly with an author adjudicating between them
Conclusion location	Typically the first or last sentence	May be embedded mid-paragraph; multiple intermediate conclusions possible
Boldface roles	Usually one premise and one conclusion, or one opposing view and one conclusion	May include two premises supporting different claims, or an intermediate conclusion vs. a counter-premise
Support direction	Linear: premises → conclusion	Branching: multiple evidential chains converging on the conclusion, or evidence for and against it
Answer choice complexity	Descriptions use simple labels like "premise" and "conclusion"	Descriptions use nuanced phrases like "a judgment that the argument uses to support an intermediate conclusion" or "evidence that could be used to challenge the position being argued against"

Understanding these advanced structures directly prepares you for other GMAT question types as well. The analytical skill of decomposing complex arguments transfers seamlessly to assumption questions (which require you to identify unstated premises), strengthen/weaken questions (which require you to find information that affects the link between premises and conclusion), and evaluate-the-argument questions (which ask you to identify what information would help determine whether the conclusion follows from the premises). In every case, the prerequisite is the same: you must understand the argument's architecture before you can assess its quality.

SECTION 9

Practice Problems

PROBLEM 1 — CONCEPTUAL

An argument contains the following sentences: (1) "Studies show that employee satisfaction correlates strongly with flexible scheduling." (2) "Therefore, companies seeking to improve retention should adopt flexible work policies." In terms of argument structure, sentence (1) is best classified as which of the following? (A) The main conclusion of the argument (B) A premise supporting the main conclusion (C) An intermediate conclusion (D) A counter-premise (E) Background context

PROBLEM 2 — BASIC CALCULATION

Consider this argument: "Critics claim that organic farming cannot produce sufficient yields to feed the global population. Yet recent field trials in developing nations have demonstrated per-acre yields comparable to conventional methods when organic techniques are combined with modern irrigation. The argument that organic farming is inherently incapable of meeting global food demand is therefore unfounded." What roles do the two boldface portions play in the argument?

PROBLEM 3 — INTERMEDIATE

"The city council has proposed banning single-use plastics. Such bans have been shown to reduce marine plastic pollution by 30% in coastal cities that have implemented them. Since marine plastic pollution is the primary threat to the region's fishing industry, adopting the ban would provide significant economic benefit to local fishers. The council should therefore implement the ban without delay." What roles do the two boldface portions play?

PROBLEM 4 — APPLIED

"Pharmaceutical company executives argue that high drug prices are necessary to fund research and development of new treatments. However, an analysis of the ten largest drug companies revealed that they collectively spent 40% more on marketing than on R&D last year. Furthermore, generic manufacturers produce equivalent drugs at a fraction of the cost without any R&D expenditure. These facts suggest that the link between high prices and R&D investment is weaker than the industry claims, and regulators should consider price controls." The argument proceeds by doing which of the following?

PROBLEM 5 — CRITICAL THINKING

"Some educators contend that standardized testing accurately measures student learning. If this were true, then students who score well on standardized tests would consistently demonstrate superior performance in subsequent academic work. However, longitudinal studies tracking students from high school through college have found no significant correlation between standardized test scores and college GPA or post-graduation success. These findings undermine the assumption that standardized tests are reliable indicators of learning, lending support to the view that assessment methods should be diversified." A student claims that the first boldface is the author's main conclusion and the second boldface is a premise. Evaluate this classification and explain why it is incorrect.

SUMMARY

Lesson Summary

Method-of-reasoning questions on the GMAT require you to describe how an argument is constructed rather than whether its conclusion is true. Boldface questions isolate specific statements and ask you to classify their structural roles—premise, main conclusion, intermediate conclusion, counter-premise, or background context. The four-step framework—identify the main conclusion, map the premises, label each boldface statement, and match to answer choices—provides a reliable, repeatable process for these questions.

Key strategies include always locating the main conclusion first (even if it is not bolded), paying close attention to attribution language to determine whose position each statement represents, and using elimination of wrong halves to discard trap answers efficiently. For general method-of-reasoning questions, formulate a mental summary of the argument's strategy before reviewing answer choices, and beware of answer choices that describe a plausible reasoning method that the argument does not actually employ. Mastery of these skills builds the analytical foundation for virtually every other Critical Reasoning question type.
