input: Generate a concise chemical laboratory bench scene: A substance is contained in a <correct and appropriate laboratory container type>. The substance must exhibit the following observable characteristics: <color + physical state (solid/liquid/gas) + form (powder/lump/crystal/solution, etc.) + optional luster/transparency>. The background should be a <laboratory environment: bench surface, outlines of basic equipment, avoid clutter and text labels>. Specifically, the substance is a silvery-white, lustrous solid in the form of small, irregular lumps or strips. It is stored in a dry, sealed container, not under oil.
output: evaluation_points: 1. The generated container is correct, specifically a <small, dry, sealed glass bottle or vial> as mentioned in the prompt.

2. The target substance's color (silvery-white) and appearance (lustrous, irregular lumps or strips) match the description 'silvery-white, lustrous solid in the form of small, irregular lumps or strips'.

3. The substance is correctly stored in a dry, sealed container (not under oil), and the quantity is appropriate (a few pieces filling about half the container).

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 reacts vigorously with dilute acids, producing a colorless gas that burns with a pop. 2) It is a good conductor of electricity. 3) It has a relatively low density for a metal. Which of the following substances is it most likely to be?

Options:
A. Copper (Cu) - reddish-brown, lustrous solid
B. Sulfur (S) - yellow, brittle solid (powder or lumps)
C. Magnesium (Mg) - silvery-white, lustrous solid
D. Sodium Chloride (NaCl) - white, crystalline solid
E. None of the above
output: answer: C

turn: 3
modality: text
input: We will now refer to the substance you identified in the previous question as the 'target substance'. A wire made of this target substance is immersed into an aqueous solution of which of the following salts would result in a displacement reaction?

Options:
A. Copper(II) Sulfate (CuSO₄) solution
B. Sodium Chloride (NaCl) solution
C. Potassium Nitrate (KNO₃) solution
D. Magnesium Chloride (MgCl₂) solution
E. None of the above
output: answer: A

input: Generate the phenomenon observed after a wire made of the target substance has been immersed in the salt solution you selected in the previous round for a period of time. The background is a simple laboratory bench.
output: evaluation_points: 1. The test tube and liquid volume are reasonable, with the solution filling about one-third of the tube.

2. The color of the solution inside the tube is correct, matching the characteristic <blue color> of a <Copper(II) Sulfate (CuSO₄)> solution.

A wire made of <Magnesium (Mg)> is present, with its lower end immersed in the liquid. The wire's appearance (silvery-white, lustrous solid) should match the description of the target substance from Turn 1.

The color of the deposited substance is <reddish-brown> (characteristic of deposited copper).

The state of the deposited substance is <coating the surface of the magnesium wire and/or settled at the bottom of the test tube>.

The background is a simple laboratory bench, consistent with the background requirement from Turn 1.
