How to Pre-Phrase LSAT Answers (Before You Read the Choices)

Pre-phrasing means deciding, in your own words, roughly what the correct answer should say before you look at the five choices. You read the stimulus, understand the argument, and form a short prediction. Then you read the answers looking for the one that matches.

It is not about guessing the exact wording. The test writers will phrase the correct answer in language you would never choose. Pre-phrasing is about knowing the job the right answer has to do — weaken this exact gap, describe this exact flaw, fill this exact assumption.

The payoff is speed and resistance to trap answers. When you walk into the answer choices with a prediction, the tempting-but-wrong options have far less pull on you.

Step 1 — Read the question stem first. Knowing whether you are weakening, strengthening, or finding an assumption tells you what kind of prediction to make. A weaken prediction looks for the gap; a main-point prediction looks for the conclusion.

Step 2 — Find the conclusion and the support, then name the gap between them. Most Logical Reasoning answers live in that gap. If you can say "the argument assumes X," you are most of the way to the answer.

Step 3 — State your prediction in a half-sentence. For a weaken question: "Something that shows the cause could be reversed." For an assumption question: "That the survey group represents everyone." Keep it short and conceptual.

Stimulus: "Sales of our energy bars rose the month after we changed the wrapper. The new wrapper clearly drove the increase."

Question: Which of the following, if true, most weakens the argument?

Pre-phrase: The argument assumes nothing else caused the sales jump. So the answer should name another cause — a price cut, a competitor going out of stock, a seasonal spike.

Now the choices feel easy. An option that says "The company also ran its first-ever television ad that month" matches your prediction instantly. You do not have to agonize over the four wrong answers, because you already know what right looks like.

Pre-phrasing is strongest on question types with predictable answer shapes: necessary assumption, weaken, strengthen, flaw, and main conclusion. These reward a clear prediction because the correct answer has a defined logical job.

It is also valuable on questions you find hard. The harder the stimulus, the more a prediction protects you from being swayed by a fluent, confident-sounding wrong answer.

Some question types resist pre-phrasing. Most strongly supported and must-be-true inference questions can have many valid-looking conclusions, so a narrow prediction may cause you to reject the correct answer because it is not what you imagined.

On those, pre-phrase loosely — predict the direction, not the destination — and lean more on eliminating answers that go beyond the stimulus. If your prediction does not appear among the choices, do not force it. Switch to elimination and ask which answer survives scrutiny.

Predicting wording instead of function. You are predicting what the answer must accomplish, not the sentence it will use.

Refusing to let go. If no choice matches your prediction, your prediction may have been too specific. Re-read the stimulus and switch to elimination rather than picking the closest-sounding option.

Skipping the conclusion. A prediction built on a misread conclusion sends you to the wrong answer with full confidence. Always confirm what the argument is actually trying to prove first.

Q: Does pre-phrasing slow me down? At first, yes. With practice it speeds you up, because you spend less time comparing five answers and more time confirming one.

Q: What if my prediction is wrong? Then elimination catches you. Pre-phrasing and elimination are partners, not rivals — use the prediction to move fast, and elimination to verify.

Q: Should I write the prediction down? On timed sections, a mental half-sentence is enough. During untimed practice, writing it out builds the habit faster.

Pre-phrasing is a habit, and habits form through repetition with feedback. Verbloom's Logical Reasoning drills include explanations that show the gap in each argument, so you can check whether your prediction matched the logical job the answer needed to do.
