16. Comets do not give off their own light but reflect light from other sources, such as the Sun. Scientists estimate the mass of comets by their brightness by their brightness: the greater a comet’s mass, the more light that comet will reflect. A satellite probe, however, has revealed that the material of which Halley’s comet is composed reflects 60 times less light per unit of mass than had been previously thought.

The statements above, if true, give the most support to which one of the following?

(A) Some comets are composed of material that reflects 60 times more light per unit of mass than the material of which Halley’s comet is composed.
(B) Previous estimates of the mass of Halley’s comet which were base on its brightness were too low.
(C) The total amount of light reflected from Halley’s comet is less than scientists had previously thought.
(D) The reflective properties of the material of which comets are composed vary considerably from comet to comet.
(E) Scientists need more information before they can make a good estimate of the mass of Halley’s comet.

答案B，我觉得B好像说翻了，C可以。请大家指教。

Totally a math question.
Formula: light=k * mass.
Now the value of light is constant, but k'= k/60, real mass surely should be 60 times than the estimated mass.

谢谢版主解答，我把light作为变量，实际变量是单位物质反射光，不小心就会落入鬼子陷阱。如果此题给出公式可出成Math文字题。也许那样我就会作了。
