turn: 1
modality: image
input: text: Based on the provided reference image of an empty room, please place the following three pieces of furniture side-by-side horizontally within the main space of the room: an operating room lamp, an operating table, and an instrument tray. Ensure there is some space between them so they do not overlap or block each other.
output: evaluation_points: 1. The image must clearly contain one of each of the three specified items: an operating room lamp, an operating table, and an instrument tray.

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 reference image.

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

turn: 2
modality: text
input: Please observe the image generated in the previous turn. Among these three newly added pieces of furniture, which one is positioned in the middle?
Options:
A. Operating room lamp
B. Operating table
C. Instrument tray
D. None of the above
E. None of the above.
output: answer: <DYNAMIC>

turn: 3
modality: image
input: Please remove the tallest piece of furniture from the three items added in the previous image. Keep all other elements unchanged.
output: evaluation_points: 1. The visually tallest furniture item (the operating room lamp) must be removed, leaving that area blank or revealing the background.

2. The position and appearance of the two remaining items (operating table and instrument tray) must not change.

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

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

turn: 4
modality: image
input: Based on the image from the previous turn, please rearrange the two remaining pieces of furniture so they are strictly aligned along a single vertical (front-to-back) line. Place the shorter item in front and the taller item behind it, creating a correct visual occlusion where the front item partially blocks the view of the back 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 furniture items (operating table and instrument tray). The removed lamp must not reappear.

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

3. The shorter item (instrument tray) must be positioned in front, and the taller item (operating table) must be positioned behind it.

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

5. The style and size of the furniture items must remain unchanged; only their position and depth order 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.
