turn: 1
modality: image
input: text: Based on the provided reference image of an empty room, please place the following three items side-by-side horizontally within the main space of the room: a cello case, a music stand, and a metronome. 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 items: a cello case, a music stand, and a metronome.

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

3. All other background elements in the image must match the original empty room reference image.

4. The image should clearly appear to be a modification of the reference image by adding objects, not a completely newly generated room.

turn: 2
modality: text
input: Observe the image generated in the previous turn. Among these three newly added items, which one is positioned in the middle?
Options:
A. Cello Case
B. Music Stand
C. Metronome
D. None of the above.
E. None of the above.
output: answer: <DYNAMIC>

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

2. The position and appearance of the two remaining items (music stand and metronome) must not change.

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

The image should clearly appear to be a modification of the Turn 1 input image, not a completely new image.

turn: 4
modality: image
input: Based on the image generated in the previous turn, rearrange the two remaining items 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 items (music stand and metronome). The removed item (cello case) 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 (metronome) must be positioned in front, and the taller item (music stand) 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 items must remain unchanged; only their position and depth relationship should be altered.

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