Incandescent lamps, like the sun, produce light by burning; the light they emit is a by-product of heat. Only a tiny percentage — 5 percent or less — of the energy used by an incandescent lamp produces light. The balance of the energy used produces heat, so incandescent lamps are supremely inefficient. But, like the sun, incandescent sources emit the visible wavelengths as a continuous band. Candlelight, firelight, and incandescent lamplight are sensed as familiar and comforting because they provide light in the same way the sun does. The apparent whiteness of the light given off by an incandescent lamp depends on the temperature at which it burns, called its color temperature.
1. What can be inferred about incandescent lamplight from the passage?
(A) So far, humanity has not been able to develop an electric source of light that is more efficient than lamplight.
(B) While incandescent lamps may produce heat, many people will continue use them because the light is familiar and comforting.
(C) Incandescent lights burn energy in the same way the sun does.
(D) Incandescent lamplight, a fire, and candlelight produce virtually the same emotional response.
(E) It would beneficial to find a way to harvest and keep the heat produced by incandescent lamplight.

(B) Incandescent lamps give off a very white light.
(C) Despite their inefficiencies, there are reasons why incandescent lamps remain popular.

3. How much is the energy of an incandescent lamp spent on tasks other than giving off light?
Explanation
So long as you read the question carefully and take a moment to a brief calculation, you’ll choose correctly. If 5 percent or less of the lamp’s energy is given to producing light, that means that 95 percent or more is given to other tasks. Choice (C) is best.

1. What can be inferred about incandescent lamplight from the passage?
Difficulty Level: 700
Explanation
With an inference question, you always want to make a short jump, not a long leap. Choice (D) represents a long leap — it may be true, but it’s not implied in the passage. Choice (B), however, is a very small hop that even uses words from the passage, making it the best choice.
