Linguists believe that select one:

(a) only 120 languages are now spoken in the world.
(b) the number of languages spoken in the world is increasing rapidly.
(c) nothing can be done to preserve linguistic diversity.
(d) all people should study english in order to facilitate cross-cultural communication.
(e) the world's linguistic diversity has been cut in half over the past 500 years.

The correct answer is letter E

Linguistic diversity, in this case, is related to the existence and coexistence of different languages. The concept defends respect for all languages and promotes the preservation of those that are on the verge of extinction due to the lack of speakers.

A language disappears when the last member of the speaking social group dies. In these cases, transmission from generation to generation through which parents teach their children's mother tongue fails. The disappearance of the language implies a very important and irrecoverable loss of knowledge: that is why linguistic diversity is equally relevant.

It is estimated that there are more than 6000 languages in the world. Oceania is the continent with the greatest linguistic diversity due to the fact that there are numerous Aboriginal groups that defend their native language. In other regions of the world, on the other hand, a dominant language has prevailed over the rest. This is the case, for example, in the United States of America, where English led to the extinction of the languages of most native inhabitants.
