# Leak Test: Option Length Shortcut (ENUMERATION Family)

You are detecting whether a question exploits option length patterns as a shortcut.

## Question

{question}

## Options

{options}

## Designated Correct Answer

{answer}

## Instructions

Check if the question can be answered by exploiting the length or specificity of options, without actually understanding the video content.

1. Is the correct answer notably longer or more specific than distractors?
2. Are distractor options clearly shorter, vaguer, or less detailed than the correct answer?
3. Could a student "game" this question by always picking the longest/most-detailed option?

If option length is an exploitable shortcut → verdict "fail".
If options are roughly balanced in length and specificity → verdict "pass".

## Response Format (strict JSON)
