Question

Passage (Michael Faraday, *The Chemical History of a Candle*, Lecture I, 1860–61, continued):

"In this wood we have one of the most beautiful illustrations of the general nature of a candle that I can possibly give. The fuel provided, the means of bringing that fuel to the place of chemical action, the regular and gradual supply of air to that place of action — heat and light — all produced by a little piece of wood of this kind, forming, in fact, a natural candle. But we must speak of candles as they are in commerce. Here are a couple of candles commonly called dips. They are made of lengths of cotton cut off, hung up by a loop, dipped into melted tallow, taken out again and cooled, then re-dipped until there is an accumulation of tallow round the cotton."

What is the function of Faraday's description of a piece of *candle-wood* in the first sentences?

Accepted Answer

B. To use a natural example that exhibits the same elements (fuel, supply of air, heat and light) as the manufactured candle, anchoring the abstract concept in something familiar.

Faraday's structure: the candle-wood illustrates *the general nature of a candle* — *fuel, means of bringing fuel, supply of air, heat and light*. He uses the familiar object to anchor the four-part abstraction. The next sentence (*But we must speak of candles as they are in commerce*) pivots to the manufactured case — making the wood serve as the natural prelude.

Answer

To argue that wood is the only natural fuel worth studying.

Answer

To distinguish naturally occurring fuels from commercially produced ones.

Answer

To recommend that listeners conduct their own experiments with wood.
