Common Wrong Answers
“A clock”
While a clock measures time and has a face, it does not serve by being devoured and is not affected by wind in the same way a candle is.
“A light bulb”
A light bulb provides light, but it is not consumed or devoured like a candle, and its lifespan is not measured in hours of burning.
“A piece of toast”
Though toast can be devoured, it does not serve a purpose in measuring time and is not affected by wind in a relevant way.
