There are roughly 21 distinct question types in LSAT Logical Reasoning, but they cluster into just seven functional groups. Once you know which group a question belongs to, you already know what to do. Below is the complete breakdown: every type, its core task, and the standard path you should follow.

Group 1: Structure Questions

Main Conclusion

Core Task: Identify the author's primary claim—the one sentence everything else supports.

Standard Path:

1. Read the stimulus and locate conclusion indicators (therefore, thus, hence, consequently).
2. Apply the "Because Test": link candidate sentences with "because." The sentence that works as the reason is the premise; the other is the conclusion.
3. Confirm by asking "So what is the author ultimately arguing?" and match to the answer choice that paraphrases that claim.

Role in Argument

Core Task: Describe the structural function of a specific bolded or referenced statement.

Standard Path:

1. Label every sentence's role: main conclusion, intermediate conclusion, premise, opposition, concession, context, or qualifier.
2. Focus on the targeted statement. Ask: "Does this support something, get supported by something, or do neither?"
3. Match the role you identified to the answer choice that describes the same structural function, ignoring choices that describe a different role.

Group 2: Patterns and Flaws

Method of Reasoning

Core Task: Describe the argumentative technique the author uses.

Standard Path:

1. Identify the conclusion and the type of evidence used (example, analogy, principle, counterexample, elimination of alternatives).
2. Characterize the move: "The author does X to establish Y."
3. Pick the answer that accurately describes that move in abstract terms.

Parallel Reasoning

Core Task: Find the answer whose argument structure mirrors the stimulus.

Standard Path:

1. Map the stimulus structure: number of premises, type of reasoning, and conclusion type (conditional, causal, comparison, etc.).
2. Note the conclusion's strength (absolute vs. qualified) and polarity (positive vs. negative).
3. Eliminate answers that differ in structure, then confirm the remaining choice matches element-by-element.

Flaw

Core Task: Name the reasoning error committed in the argument.

Standard Path:

1. Find the conclusion and the evidence. Identify the gap between them.
2. Classify the gap using your flaw taxonomy: conditional error, causal error, equivocation, sampling error, appeal to authority, part-to-whole, ad hominem, false dichotomy, circular reasoning, etc.
3. Match the classification to the answer choice that names or describes that specific error.

Parallel Flaw

Core Task: Find the answer that commits the same type of reasoning error as the stimulus.

Standard Path:

1. Identify the flaw in the stimulus using the Flaw method above.
2. Scan the answer choices for arguments that commit the same category of error.
3. Verify that the structural pattern of the flaw (not just the topic) matches.

Group 3: Evaluate / Help / Hurt

Evaluate the Argument

Core Task: Identify the question whose answer would help determine whether the argument is strong or weak.

Standard Path:

1. Find the conclusion and the key assumption or gap.
2. For each answer, test: "If the answer to this question is yes, does it affect the argument? If no?" The correct answer matters either way.
3. Eliminate choices where the answer would be irrelevant regardless of the response.

Strengthen

Core Task: Find the answer that most supports the argument's conclusion.

Standard Path:

1. Identify the conclusion and the gap between the evidence and that conclusion.
2. Pre-phrase: "What additional fact would help bridge this gap?"
3. Pick the answer that, if true, makes the conclusion more likely. It does not need to prove the conclusion—just nudge it.

Weaken

Core Task: Find the answer that most undermines the argument's conclusion.

Standard Path:

1. Identify the conclusion and the gap.
2. Pre-phrase: "What fact would exploit this gap and make the conclusion less likely?"
3. Pick the answer that, if true, damages the link between the evidence and the conclusion. It does not need to destroy the argument—just weaken it.

Sufficient Assumption

Core Task: Find the answer that, if added as a premise, makes the conclusion follow with certainty.

Standard Path:

1. Identify the conclusion and list every premise.
2. Find the logical gap—the missing link that, once supplied, would make the argument airtight.
3. Pick the answer that, combined with the existing premises, guarantees the conclusion. This is often the most powerful (and broadest) answer.

Necessary Assumption

Core Task: Find the answer that the argument requires to be true—without it, the argument falls apart.

Standard Path:

1. Identify the conclusion, evidence, and gap.
2. Pre-phrase what the author must be taking for granted.
3. Apply the Negation Test: negate each answer choice. If negating it destroys the argument, it is a necessary assumption. If the argument survives the negation, eliminate that choice.

Group 4: Principle Questions

Principle — Strengthen

Core Task: Find the general rule that, if true, most justifies the argument.

Standard Path:

1. Organize the argument into evidence and conclusion.
2. Pre-phrase the gap as a general rule: "If [situation described], then [conclusion drawn]."
3. Pick the answer whose "if" matches the evidence and whose "then" matches the conclusion.

Principle — Illustrate

Core Task: Given a general principle in the stimulus, find the specific scenario that correctly illustrates it.

Standard Path:

1. Translate the principle into a conditional or rule.
2. For each answer, check: does the scenario meet the rule's conditions, and does the outcome match what the rule prescribes?
3. Pick the answer that is a valid application of the rule.

Principle — Apply

Core Task: Apply a general principle from the stimulus to reach a specific conclusion.

Standard Path:

1. Translate the principle into clear conditional logic.
2. Identify which facts in the scenario trigger the principle.
3. Determine the conclusion that the principle, applied to those facts, produces. Match to an answer.

Group 5: Inference Questions

Most Strongly Supported (MSS)

Core Task: Find the answer best supported by the stimulus—but not necessarily proven by it.

Standard Path:

1. Read the stimulus as a set of facts (not an argument to critique).
2. For each answer, ask: "Does the stimulus give me good reason to believe this?"
3. Eliminate answers that go beyond the stimulus, contradict it, or are unsupported. Prefer the most cautious, well-grounded choice.

Fill in the Blank

Core Task: Complete the argument's final sentence so the reasoning is logically sound.

Standard Path:

1. Read the stimulus up to the blank. Determine whether the blank is a conclusion or a premise based on context clues.
2. If the blank is a conclusion, ask what logically follows from the evidence. If it is a premise, ask what fact is needed to support the stated conclusion.
3. Pick the answer that makes the argument coherent and complete.

Must Be True (MBT)

Core Task: Find the answer that is guaranteed by the stimulus.

Standard Path:

1. Treat the stimulus as a set of premises. Look for conditional chains, overlapping quantifiers, or deductive structures.
2. Combine the premises to see what necessarily follows.
3. Pick the answer that cannot be false given the information provided.

Must Be False (MBF)

Core Task: Find the answer that is directly contradicted by the stimulus.

Standard Path:

1. Treat the stimulus as a set of premises.
2. For each answer, check if it conflicts with any stated or deducible fact.
3. Pick the answer that cannot be true given the information.

Group 6: Paradox / Resolve

Paradox (Explain / Resolve)

Core Task: Find the answer that explains how two apparently conflicting facts can both be true.

Standard Path:

1. Identify the two facts that seem to contradict each other.
2. Ask: "What additional information would make both facts simultaneously possible?"
3. Pick the answer that bridges the gap and removes the apparent contradiction without denying either fact.

Group 7: Dialogue Questions

Point of Agreement

Core Task: Find the claim that both speakers would endorse.

Standard Path:

1. Read both speakers' positions and identify their premises, conclusions, and assumptions.
2. For each answer, confirm that Speaker 1 would agree AND Speaker 2 would agree. If either would disagree or be neutral, eliminate.

Point of Disagreement

Core Task: Find the claim that one speaker would accept and the other would reject.

Standard Path:

1. Read both speakers and identify where their positions diverge.
2. For each answer, confirm that Speaker 1 holds one position and Speaker 2 holds the opposite. Both must have a committed stance—if either is silent on the issue, eliminate.

How to Use This Cheat Sheet

When you sit down with a Logical Reasoning section, read the question stem first. Classify it into one of the seven groups above. Then follow the standard path for that type. Over time, classification becomes instant and the standard paths become second nature. That is when your accuracy and speed both improve together.
