21. Efficiency and redundancy are contradictory characteristics of linguistic systems: however, they can be used together to achieve usefulness and reliability in communication. If a spoken language is completely efficient, then every possible permutation of its basic language sounds can be an understandable word. However, if the human auditory system is an imperfect receptor of sounds, then it is not true that every possible permutation of a spoken languageâ€™s basic language sounds can be an understandable word.

If all of the statements above are true, which one of the following must also be true?

(A) Efficiency causes a spoken language to be useful and redundancy causes it to be reliable.
(B) Neither efficiency nor redundancy can be completely achieved in spoken language.
(C) If a spoken language were completely redundant, then it could not be useful.
(D) If the human auditory system were a perfect receptor of sounds, then every permutation of language sounds would be an understandable word.
(E) If the human auditory system is an imperfect receptor of sounds, then a spoken language cannot be completely efficient.

E is the only answer that makes sense since for a language to be efficient then every possible permutation of its sounds CAN be an understanble word and thats possilbe only if the human auditory system if a perfect receptor of sound

All others make assumptions that are not GIVEN in the text

It is E

D is incorrect because, for every permutation of language sounds to be an understandable word, the auditory system should be perfect receptor and the language should be efficient. Since the language efficiency is missing D cannot be inferred.
