Explanation
A. The passage does not claim that English is supplanting native languages due to Internet use, nor does it state that this has reversed the resurgence of native languages. This is not presented as the main point in any part of the passage.
B. (Correct Response) The main point of the passage is that native language radio programming is instrumental in preserving native languages. This is supported in paragraph two, where radio is described as a particularly effective tool due to the oral traditions of indigenous cultures. The passage also recognizes the threat of the Internet to native languages and implies that radio might help counter this threat.
C. The passage (paragraphs one and two) does not argue that radio is the only viable means for preserving native languages, just that it is a particularly effective one due to its alignment with the oral traditions of indigenous cultures.
D. While the passage does argue for incorporating cultural context into language preservation, it does not present this as the overarching main point; instead, it is mentioned as a part of effective programming described in paragraph two on the right side.
E. The passage (paragraph two) mentions that radio engages older people in preserving their languages but does not claim this as the primary reason for its success, nor does it establish this as the main point.
The second paragraph of the passage explicitly discusses the value of native language radio programming as a vital tool for the preservation of native languages. It suggests that this method aligns well with the oral traditions of indigenous cultures and provides a widely accessible means for diffusion. The same paragraph also acknowledges the potential threat posed by the Internet to the preservation efforts of native languages, indicating that radio might be a counter to this new challenge.
