What is the main argument regarding artificial light made in the passage?

• A. Flames produce more carbon pollution than required.
• B. Flames are primarily a source of warmth and comfort.
• C. The brightness of flames is due to incandescence of carbon.
• D. All forms of artificial light are dangerous.

Answer: (C)

The main argument about artificial light highlighted in the passage emphasizes that the brightness of flames can be attributed to the incandescence of carbon. This assertion focuses on the scientific explanation for why flames emit light, showcasing the physical processes involved. Incandescence refers to the light produced by heating a material until it glows; in the case of flames, it is the carbon particles that emit light when they reach a high temperature. This choice effectively captures the essence of the discussion around the properties of light generated by flames, distinguishing it from other forms of artificial lighting and their mechanisms. Additionally, it provides insight into the characteristics of flames as a source of light rather than focusing solely on their environmental impact, warmth, or perceived dangers.
