According to the passage regarding artificial light, what is a notable characteristic of flames?

• A. They are the most environmentally-friendly form of lighting.
• B. They primarily produce heat, rather than light.
• C. They are convenient but not very efficient.
• D. They are the only source of brightness available.

Answer: (C)

Flames possess the characteristic of being convenient for providing light in certain scenarios, such as in candles or fireplaces. However, they are often considered inefficient in terms of energy use compared to modern lighting options like LEDs or fluorescents. While flames do produce light, the amount of light they provide relative to the energy consumed is lacking, which is why they are not typically used as a primary lighting source in contemporary settings. This combination of convenience and inefficiency makes the option noteworthy when discussing the advantages and disadvantages of various lighting forms.
