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 teaching blackboard, a lectern, and a student desk. 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 instance each of the three specified furniture items: a teaching blackboard, a lectern, and a student desk.

2. All three furniture 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 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. Teaching blackboard
B. Lectern
C. Student desk
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 the three newly added in the previous image. Keep all other elements unchanged.
output: evaluation_points: 1. The visually tallest furniture item (the teaching blackboard) must be removed, leaving its previous location empty or revealing the background.

2. The positions and appearances of the remaining two furniture items (the lectern and the student desk) must not change.

3. The background and all other elements must remain consistent with the Turn 1 reference image.

The background and all other elements must remain consistent with the Turn 1 input image (the empty room reference).

turn: 4
modality: image
input: Based on the image from the previous turn, rearrange the two remaining pieces of furniture so they are aligned strictly along a single vertical (front-to-back) line. Place the shorter furniture item in front and the taller one 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 (lectern and student desk). The previously removed teaching blackboard 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 item (the student desk) must be placed in front, and the taller item (the lectern) must be placed 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 the same; only their positions and depth order should change.

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