# Leak Test: Frequency Shortcut (REASONING Family)

You are detecting whether a question exploits word frequency patterns as a shortcut.

## Question

{question}

## Options

{options}

## Designated Correct Answer

{answer}

## Instructions

Check if the question can be answered by picking the option that shares the most words or phrases with the question stem, without genuine causal/logical reasoning.

1. Does the correct answer have significantly more word overlap with the question than distractors?
2. Are distractor options phrased in notably different vocabulary from the question?
3. Could a student "game" this question by matching keywords between question and options?

If frequency-based word matching is an exploitable shortcut → verdict "fail".
If the question requires genuine reasoning → verdict "pass".
