turn: 1
modality: image
input: Please generate a simple chemical laboratory bench scene: A substance is contained in a suitable laboratory container. The substance must have the following observable characteristics: It is a dark red solid in the form of a powder, with a dull, non-metallic appearance. The background should be a laboratory environment with a bench and basic equipment outlines, avoiding clutter and text labels.
output: evaluation_points: 1. The generated container is correct and is indeed a reagent bottle or a watch glass, suitable for holding a solid powder.

2. The color and appearance of the target substance (dark red, dull, fine powder) match the described morphological features.

3. The substance is appropriately contained in the vessel (e.g., not overflowing, not a single lump).

4. The background is a simple laboratory bench scene.

input: Based on the appearance of the substance in the input image, and given that this substance is known to have the following properties: (1) It is insoluble in water and common organic solvents. (2) It is relatively stable in air at room temperature but can ignite upon strong heating. (3) It is a non-conductor of electricity. Which of the following substances is it most likely to be?
Options:
A. Copper(II) oxide (CuO) - a black solid powder
B. Sulfur (S) - a yellow solid powder
C. Potassium permanganate (KMnO₄) - dark purple, almost black crystals
D. Iodine (I₂) - shiny, dark gray to purple-black crystals
E. None of the above
output: answer: E

input: We will subsequently refer to the substance you identified earlier as the 'target substance'. The target substance can undergo a reaction where it is heated strongly in the presence of air/oxygen. Please generate the state of the experiment on the bench during this normal reaction (experimental apparatus, substance states, and reaction phenomena should be reasonable and self-consistent).
output: evaluation_points: 1. The selection, connection, and use of experimental instruments are correct and match the combustion reaction of the target substance (e.g., a crucible or evaporating dish on a clay triangle over a Bunsen burner).

The target substance is generated in the correct form (dark red, dull, fine powder) in the correct location (e.g., inside the crucible).

3. The reaction atmosphere (air/oxygen) is implied by the open setup.

4. The reaction phenomenon matches 'vigorous combustion producing dense white fumes/smoke'.

The picture background is a simple laboratory bench scene, consistent with the background in the Turn 1 output image.

input: If, in the above normal reaction, the experimental setup is incorrectly changed to 'heating the substance in a sealed container', what is the most likely accident to occur?
Options:
A. The substance fails to react due to lack of oxygen.
B. The container ruptures due to a rapid pressure increase from gas production.
C. The substance melts and flows out of the container.
D. A toxic, colorless gas is released without warning.
E. None of the above.
output: answer: B

turn: 5
modality: text
input: Regarding the experimental accident described in the previous question, what is the most correct way to handle it?
Options:
A. Immediately open the sealed container to release the pressure.
B. Evacuate the area, allow the container to cool completely before cautiously inspecting it from a distance, and wear appropriate PPE.
C. Submerge the hot, sealed container in cold water to cool it down rapidly.
D. Use a fire extinguisher to spray the container directly.
E. None of the above.
output: answer: B
