# Leak Test: Spatial Default Shortcut (SPATIAL Family)

You are detecting whether a question exploits spatial default assumptions as a shortcut.

## Question

{question}

## Options

{options}

## Designated Correct Answer

{answer}

## Instructions

Check if the question can be answered by relying on common spatial assumptions (e.g., "center of frame", "left to right", "foreground") without actual visual understanding.

1. Is the correct answer the "default" spatial position people would assume (e.g., center, front)?
2. Are distractor options in positions that seem intuitively unlikely (e.g., extreme edges, behind)?
3. Could a student "game" this question by always picking the spatially default/expected option?

If spatial defaults are an exploitable shortcut → verdict "fail".
If the question requires genuine spatial reasoning → verdict "pass".
