input: Among the following substances, which ones are characterized by being colorless or white crystalline solids at room temperature, possessing a distinct, sweet, tarry odor, and being moderately soluble in water? (Select all that apply)
A. Sodium chloride (NaCl)
B. Phenol (C6H5OH)
C. Acetic acid (CH3COOH, glacial)
D. Benzoic acid (C6H5COOH)
E. None of the above
output: answer: B, D

turn: 2
modality: image
input: It is known that the target substance is one of the correct options from the previous question and has the following additional property: it is hygroscopic, corrosive, and must be stored in an airtight, light-resistant container to prevent absorption of moisture and oxidation. Please generate an image showing this target substance stored correctly in its proper container and placed on a laboratory bench.
output: evaluation_points: 1. The container generated in the image is correct: it must be an airtight, amber glass bottle with a secure cap, consistent with the requirement for light protection and moisture prevention as described in the turn 2 input text.

2. The substance generated is indeed phenol: it should appear as colorless to white needle-like or crystalline solid chunks or powder, consistent with the description 'colorless or white crystalline solid' from turn 1 input text.

3. The substance is correctly contained within the airtight amber glass bottle, with a suitable fill level (e.g., half to three-quarters full).

4. The background is a simple laboratory bench scene, as required by the turn 2 input text.

turn: 3
modality: image
input: We will now refer to the substance you identified earlier as the 'target substance'. There are two test tubes placed side-by-side. The left test tube contains a moderate amount of Acid A = dilute hydrochloric acid (HCl, aq). The right test tube contains a moderate amount of Acid B = concentrated nitric acid (HNO3, aq). An identical solid sample of the target substance is simultaneously added to both tubes. Please generate an image representing the phenomena observed in both test tubes at the same moment during the reaction. The background is a simple laboratory bench.
output: evaluation_points: 1. The image accurately depicts exactly two test tubes, placed side-by-side (left and right), as described in the turn 3 input text. The liquid volume in each tube is safe and reasonable (e.g., 2-3 mL).

2. The solution colors match the description from the turn 3 input text: the left tube contains a colorless dilute hydrochloric acid solution; the right tube contains a colorless concentrated nitric acid solution.

3. The phenomenon in the left test tube matches the description: 'The solid phenol dissolves slowly in dilute hydrochloric acid without any vigorous reaction, gas evolution, or significant color change.' (This description is based on chemical knowledge and the turn 3 input text specifying the setup.)

4. The phenomenon in the right test tube matches the description: 'Upon contact with concentrated nitric acid, the solid phenol undergoes a vigorous nitration reaction, producing a yellow to orange/brown colored solution or mixture, potentially with slight fuming or heat evolution.' (This description is based on chemical knowledge and the turn 3 input text specifying the setup.)

5. The image background is a simple laboratory bench, as required by the turn 3 input text.

input: Based on the difference in phenomena observed in the two test tubes in the input image, what is the most fundamental cause for this difference?
A. The difference in the electrical conductivity of the two acid solutions.
B. The difference in the oxidizing strength of the two acids, with one acid acting as a strong oxidizing agent capable of nitrating aromatic rings.
C. The difference in the reaction rate due solely to the concentration of H+ ions.
D. The difference in the volatility of the two acids.
E. None of the above.
output: answer: B
