input: Generate a concise chemical laboratory bench scene: A substance is contained in a <correct and appropriate laboratory container type>. This substance must have the following observable appearance: <must include color + physical state (solid/liquid/gas) + form (powder/lump/crystal/solution, etc.) + optional luster/transparency; the name, chemical formula, or element symbol of the substance is prohibited>. The background should be a <laboratory environment: bench surface, outlines of basic equipment only, avoid clutter and text labels>.
output: evaluation_points: 1. The container generated in the image is correct and is indeed a watch glass.

2. The color and appearance (powder/crystal/lump/solution, etc.) of the target substance conform to 'bright yellow, solid, fine powder'.

3. The substance is appropriately contained on the watch glass in a suitable quantity.

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 has the following properties: 1) It is insoluble in water but soluble in carbon disulfide. 2) It melts at a relatively low temperature (around 115°C) to form a mobile dark red liquid. 3) It burns in air with a pale blue flame, producing a pungent, choking gas. Which of the following substances is it most likely to be?

Options:
A. Iron(III) oxide powder (Fe₂O₃)
B. Sodium chloride crystals (NaCl)
C. Sulfur powder (S)
D. Copper(II) sulfate pentahydrate crystals (CuSO₄·5H₂O)
E. None of the above
output: answer: C

modality: image
input: We will subsequently refer to the substance you identified earlier as the 'target substance'. When <preparing a solution of the target substance in carbon disulfide for a reaction or solubility test> the laboratory instrument <fume hood> is used. Please generate an image representing the correct use of this instrument in this scenario. The background is a simple laboratory bench.
output: evaluation_points: 1. The correct laboratory instrument, a fume hood, is generated in the image, and its placement is reasonable.

2. The reaction or procedure depicted (preparing a solution in carbon disulfide) and the conditions (use of a volatile, toxic solvent) are consistent with the scenario described in the prompt.

3. The fume hood is shown being used correctly: the sash is at a safe working height, apparatus is placed well inside the hood, and it is operational (implied by airflow).

4. The background is a simple laboratory bench scene.

input: Based on the instrument and operational scene in the input image, determine which of the following statements about this instrument and its usage protocols are correct.

Options:
A. This instrument is primarily used to protect the user from inhaling toxic fumes or gases.
B. It is acceptable to store large, unused chemical bottles inside this instrument permanently.
C. The transparent front panel (sash) should always be fully raised to its maximum height during use for best visibility.
D. Experiments involving volatile organic solvents should always be conducted inside this instrument.
E. The airflow indicator, if present, should be checked regularly to ensure proper operation.
F. This instrument can completely eliminate the need for wearing personal protective equipment like safety glasses.
G. None of the above are correct.
output: answer: A, D, E
