input: The target substance is one of the correct options from the previous question. It is a gas that must be stored in a gas cylinder or a gas collection bottle, typically with the container mouth oriented downwards. Please generate an image showing this target substance being stored correctly in its appropriate container and placed on a laboratory bench.
output: evaluation_points: 1. The container depicted is correct: a gas cylinder or a gas collection bottle (e.g., a gas jar or a bottle with a ground glass stopper).

3. The gas is stored in the container with the container mouth oriented downwards, as hydrogen is less dense than air and this positioning helps prevent its escape.

4. The background is a clean, uncluttered laboratory bench scene.

2. The flame color is a pale blue or nearly colorless flame, which is characteristic of the clean combustion of hydrogen gas in air. (The target substance is hydrogen gas (H₂), as determined by the correct answer from Turn 1).
