Reading Comprehension — Argument Passages

What This Module Covers

This module focuses on argument-based RC questions — the subtype where the passage presents a short argument and asks you to Strengthen it, Weaken it, identify its Assumption, or Resolve a Paradox. These are not the same as long-passage comprehension questions. You are not reading for the big picture here — you are dissecting a tight logical structure.

Why It Matters on the GRE

Argument RC questions appear consistently on every GRE Verbal section, and they reward a different skill set than traditional reading comprehension. Students who try to "feel out" the right answer on these questions lose points to well-crafted traps. The RAMA framework — Re-phrase, Anticipate, Match, Awareness — is your antidote to that. Master the framework and you will handle every question type in this module with precision.

Core Concepts

Argument Structure — Know This Cold

Every GRE argument has exactly three parts, and identifying all three before you look at the answer choices is non-negotiable.

1. Conclusion — The main claim the author is arguing for. Watch for signal words: therefore, thus, hence, so, this suggests, consequently, it follows that. The conclusion is the destination of the argument.

2. Premises — The evidence or reasons given to support the conclusion. These are the facts the author is treating as true. Premises are your starting point for anticipation.

3. Assumption — An unstated premise the argument depends on. The assumption is the gap between the evidence and the conclusion. If the assumption is false, the entire argument collapses — even if the premises are true.

Must Know: If you can't identify the assumption, you cannot reliably weaken, strengthen, or evaluate the argument. Find the gap first.

Example: "Sales of electric vehicles rose 40% after gas prices doubled. Therefore, high gas prices are driving EV adoption." The premise is the correlation. The assumption is that the correlation is causal — that the gas price increase caused the EV sales rise, not that some third factor (like a new tax credit) drove both. Every attack on this argument goes through that assumption.

The RAMA Framework for Argument Questions

RAMA gives you a repeatable process so you never approach these questions blind.

1. Re-phrase the question — Before you read the passage, read the question stem and categorize it: Strengthen, Weaken, Assumption, Paradox/Resolve, or Purpose. Each type has a different target, and confusing them is the most common way to pick a wrong answer that "sounds right."

2. Anticipate — Before you look at the choices, ask yourself: what would the ideal answer look like? For a weaken question, ask "what gap in this argument could be attacked?" For an assumption question, ask "what does this argument silently depend on?" Pre-thinking an answer type makes you far less vulnerable to trap choices.

3. Match to choices — Scan the five choices for the one that best fits your anticipation. You are not looking for a perfect match in wording — you are looking for a functional match. Train yourself to evaluate what each choice does to the argument, not just what it says.

4. Awareness of traps — Before you commit to your answer, quickly check whether it falls into a common trap pattern. The most dangerous traps are listed in the Common Traps section below. Thirty seconds of trap-checking will save you from a lot of avoidable wrong answers.

Must Know: RAMA is not just a reading trick — it is a structural process. Apply all four steps every time, in order, until it becomes automatic.

Question Type: Strengthen

A correct Strengthen answer makes the conclusion more likely to be true. It doesn't have to prove the conclusion — it just needs to raise the probability that the conclusion follows from the premises. Think of it as plugging a hole in the argument.

Must Know: Strengthen answers often support the assumption. If the argument assumes X is true, an answer that confirms X strengthens the argument.

Question Type: Weaken

A correct Weaken answer makes the conclusion less likely to be true. The most effective attacks go after the assumption — if you show that the unstated premise is false or doubtful, the whole argument falls apart. Finding the assumption first is the fastest path to the weaken answer.

Must Know: Weaken answers do not have to disprove the conclusion. They only need to reduce confidence in it.

Question Type: Assumption (Negation Test)

The assumption is the unstated premise the argument depends on. To find it among five choices, use the Negation Test: negate each answer choice and ask whether negating it destroys the argument. If negating a choice makes the conclusion impossible or highly unlikely, that choice is the assumption. If negating a choice has no effect on the argument, eliminate it.

Must Know: You are not looking for a statement you agree with. You are looking for a statement the argument cannot survive without.

Example: Argument: "Our restaurant uses locally sourced produce, so our food is healthier than the competition." Assumption candidate: "Locally sourced produce is healthier than non-locally sourced produce." Negate it — "Locally sourced produce is NOT healthier" — and the conclusion evaporates. That's the assumption.

Question Type: Paradox / Resolve the Discrepancy

The passage presents two facts that seem to contradict each other. Your job is to find the answer that explains how both facts can be true at the same time. This is different from Strengthen/Weaken — you are not evaluating an argument, you are reconciling two observations.

Must Know: The correct answer must address BOTH contradictory facts. If a choice explains one but ignores the other, it's a trap.

Question Type: Purpose of Detail

The question asks why the author included a specific piece of information. Answer in terms of function, not content. The correct answer will say things like "to provide evidence for the main claim," "to introduce a counterexample," or "to anticipate an objection." Do not pick choices that simply describe what the detail says — pick the one that explains why it's there.

Common Traps

• Scope Creep on Strengthen/Weaken: The wrong answer addresses an issue that sounds related to the argument's topic but doesn't connect to the core conclusion. If the conclusion is about gas prices and EVs, an answer about EV charging infrastructure may sound relevant but misses the actual claim. Always ask: "Does this choice affect the specific conclusion?"

• Forgetting the Negation Test for Assumptions: Students often pick the "most true-sounding" statement rather than the necessary assumption. True-sounding ≠ necessary. Run the negation test before you commit.

• Half-Solving the Paradox: The choice explains one of the two contradictory facts but ignores the other. Read both facts carefully and confirm your answer accounts for both before selecting it.

• Too Extreme on Strengthen/Weaken: An answer that would completely prove or disprove the conclusion goes further than the question asks. Strengthen questions only need increased probability; Weaken questions only need decreased probability. Choices that say "conclusively demonstrates" or "proves beyond doubt" are almost always wrong.

• Opposite Trap: On weaken questions especially, one of the five choices will actually strengthen the argument. This is placed to catch students who are moving too fast. If a choice makes the conclusion more likely, eliminate it immediately.

GRE Strategy

• Always read the question stem before the passage. Knowing what type of question you're answering shapes how you read the argument.
• Break every argument into its three parts (conclusion / premises / assumption) before reading the choices.
• Pre-think your answer on every question. One sentence is enough: "I'm looking for something that shows the cause was X, not Y."
• Eliminate choices based on what they do to the argument — attack, support, or nothing. "Nothing" choices are always wrong.
• On Paradox questions, underline the two contradictory facts before reading choices. Then hold both in mind as you evaluate each option.

Worked Example

Question:

In a recent study, students who slept at least 8 hours the night before an exam scored 15% higher on average than those who slept fewer than 6 hours. Therefore, educators should require students to go to bed by 10 PM the night before any major exam.

Which of the following, if true, most weakens the argument above?

(A) Some students who slept 8 or more hours still performed poorly on the exam. (B) The correlation between sleep duration and performance was observed in only two schools. (C) Students who typically sleep 8 or more hours also tend to study more thoroughly throughout the semester. (D) The exams in the study covered topics of varying difficulty. (E) School administrators cannot legally require students to follow a specific bedtime.

Solution:

Step 1 — Re-phrase: This is a Weaken question. I need to find the choice that makes the conclusion less likely to follow from the evidence.

Step 2 — Anticipate: The conclusion is that educators should mandate a 10 PM bedtime. The evidence is that students who slept 8+ hours scored 15% higher. The key assumption connecting those two things is that the sleep itself caused the higher scores — that it wasn't something else going on. If I can show that some other factor actually explains the score difference, the causal claim falls apart and the bedtime mandate has no logical support. I'm looking for an alternative explanation.

Step 3 — Match: Choice (C) says that students who sleep 8+ hours also tend to study more thoroughly throughout the semester. That's a direct alternative explanation: the higher scores might be caused by better study habits, not the extra sleep. If studying is the real driver, then mandating sleep won't produce the gains the author promises — the argument's causal foundation is undermined.

Step 4 — Awareness / Eliminate the others:

• (A) is tempting but irrelevant. The argument is about averages — of course some high-sleep students still scored poorly. This doesn't attack the overall trend or the causal claim. It's out of scope.
• (B) raises a concern about sample size, but the argument doesn't depend on the study being large-scale — it just cites a correlation. This weakens the study's reliability but doesn't cut to the argument's core assumption about causation.
• (D) introduces varying exam difficulty, which could affect scores — but this affects both the high-sleep and low-sleep groups randomly and doesn't target the causal assumption. It's too vague to meaningfully weaken the conclusion.
• (E) is a practical objection (legal authority), not a logical attack on the argument. The argument's logic could still be valid even if administrators happen to lack the legal authority to enforce it. This doesn't weaken the reasoning, only the implementation.

Answer: (C)

Choice (C) directly attacks the assumption that sleep caused the higher scores by introducing a confounding variable — study habits — that could explain both the longer sleep and the better performance. If studious students both sleep more and study more, the sleep is just correlated with, not responsible for, their success. The bedtime mandate would then have no logical basis.
