LIGHT: BLIND 1 pointA. speech: dumbB. language: deafC. tongue: soundD. voice: vibration

The question seems to be a type of analogy question often found in IQ or standardized tests. The analogy is "LIGHT: BLIND". This means that light is to blind as what is to what?

The answer is A. speech: dumb.

The reasoning is that light is something that cannot be perceived by someone who is blind, just as speech is something that cannot be produced by someone who is dumb (in the old-fashioned sense of the word meaning unable to speak).

The other options do not fit the analogy. For example, a deaf person can still use language, just not through the auditory channel. A tongue produces sound, but sound is not equivalent to speech. And a voice produces vibration, but vibration is not equivalent to speech.
