turn: 1
modality: text
input: Which of the following substances are characterized by being a soft, silvery-white metal that reacts violently with water and must be stored under an inert liquid to prevent contact with air and moisture?

Options:
A. Potassium metal
B. Calcium carbonate powder
C. Sodium metal
D. Concentrated sulfuric acid
E. Iodine crystals
F. Magnesium ribbon
G. None of the above
output: answer: A, C

turn: 2
modality: image
input: It is known that the target substance is one of the correct options from the previous question. Furthermore, this substance is stored under a layer of mineral oil or kerosene in a sealed glass container to prevent its oxidation and violent reaction with atmospheric moisture. Please generate an image showing this target substance stored correctly in its proper container, placed on a laboratory bench.
output: evaluation_points: 1. The container generated in the image is correct; it is indeed a sealed glass jar or bottle.

2. The substance generated in the image is indeed sodium metal, with a color and appearance (silvery-white, soft, solid chunks) consistent with the described characteristics.

3. The substance is correctly contained within the jar, submerged under a clear layer of mineral oil or kerosene, with an appropriate amount of the substance visible.

4. The background is a simple laboratory bench scene.

turn: 3
modality: image
input: We will subsequently refer to the substance you identified earlier as the 'target substance'. The target substance can react with water at room temperature, producing a flammable gas and a strongly alkaline solution. Please generate the state of the laboratory bench during this normal reaction, with experimental apparatus, substance states, and reaction phenomena all being reasonable and self-consistent.
output: evaluation_points: 1. The selection, connection, and use of experimental apparatus are correct and match the reaction of sodium with water (e.g., a beaker, forceps, safety screen).

2. The target substance (sodium metal) is generated in the correct form (a small, silvery-white chunk) at the correct location (e.g., on the surface of the water or just dropped in), with color and state consistent with its characteristics.

3. The reactant (water) in the beaker is generated correctly as a clear, colorless liquid.

4. The reaction phenomenon is consistent with the described 'production of a flammable gas and a strongly alkaline solution', which may be depicted as vigorous bubbling/effervescence, the sodium metal moving rapidly on the water surface, and possibly the formation of a colorless solution.

5. The image background is a laboratory bench.

turn: 4
modality: text
input: If, in the normal reaction described above, the water is mistakenly replaced with a large volume of concentrated hydrochloric acid, what is the most likely accident to occur?

Options:
A. A slow, controlled reaction producing a salt solution.
B. A violent, explosive reaction due to the rapid generation of hydrogen gas and significant heat.
C. The formation of a dense, white precipitate.
D. No visible reaction occurs.
E. None of the above.
output: answer: B

turn: 5
modality: image
input: Please generate the scene of the experimental accident described in the previous question and show the correct way to handle this accident.
output: evaluation_points: 1. The image correctly depicts the aftermath of the accident: a violent reaction scene with possible splashing of acid, rapid gas evolution, and heat (suggested by steam or vigorous bubbling).

2. The image shows the correct accident handling method, which involves using a dry chemical (Class D) fire extinguisher or smothering with dry sand to extinguish any metal fire, and NOT using water.

The background and other unrelated elements remain consistent with the laboratory bench scene from turn 2's output image, with no significant changes.

The image is clearly a modified version of the reaction scene from turn 3's output image, not a completely newly generated picture (e.g., same bench setup but with added fire/smoke/extinguisher).
