turn: 1
modality: image
input: text: Based on the provided empty room reference image, please place the following three pieces of furniture side-by-side horizontally within the main space of the room: a standing water dispenser, a desk, and a wastepaper basket. Ensure there is some space between them and they do not overlap or block each other.
output: evaluation_points: 1. The image must clearly contain one instance each of the three specified items: a standing water dispenser, a desk, and a wastepaper basket.

2. All three items must be arranged horizontally (left-to-right), not stacked or placed in a front-to-back line.

3. All other background elements and the room layout must remain identical to the provided empty room reference image.

4. The image must clearly appear to be a modification of the reference image (e.g., by adding objects), not a completely newly generated room.

turn: 2
modality: text
input: Observe the image generated in the previous turn. Among the three newly added pieces of furniture, which one is positioned in the middle?

Options:
A. Standing water dispenser
B. Desk
C. Wastepaper basket
D. None of the furniture is in the middle
E. None of the above.
output: answer: <DYNAMIC>

turn: 3
modality: image
input: Please remove the tallest piece of furniture from among the three newly added items in the previous image. Keep all other elements unchanged.
output: evaluation_points: 1. The visually tallest piece of furniture (the standing water dispenser) must be removed, leaving its location empty or revealing the background.

2. The positions and appearances of the two remaining pieces of furniture (the desk and the wastepaper basket) must not change.

The background and all other unrelated elements must remain consistent with the Turn 1 input image.

4. The image must clearly appear to be a modification of the reference image, not a completely new scene.

turn: 4
modality: image
input: Based on the image generated in the previous turn, please rearrange the two remaining pieces of furniture so they are aligned strictly along a single vertical (front-to-back) line. Place the shorter furniture in front and the taller furniture behind it, creating a correct visual occlusion relationship where the front item partially blocks the view of the rear item. Keep all other environmental elements unchanged. Please generate the adjusted room layout.
output: evaluation_points: 1. The image must contain only the two remaining pieces of furniture (desk and wastepaper basket). The removed standing water dispenser must not reappear.

2. The two items must be aligned along a single front-to-back axis, not offset left or right from each other.

3. The shorter furniture (wastepaper basket) must be placed in front, and the taller furniture (desk) must be placed behind it.

4. The front furniture must visually occlude part of the rear furniture, establishing a clear foreground/background relationship.

5. The style and size of the furniture must remain unchanged; only their positions and depth relationship should be altered.

The room background must remain consistent with the Turn 1 input image, and the image should appear as a continuous modification from the previous steps.
