I'm sorry but I still fail to understand the answer
Maybe I should try explaining my reasoning:
A, B, and C I eliminated right off the bat.
A- The issue is that the native speakers perception of sounds are an illusion. If anything this strengthens it, because the native speakers perceptions might be faulty themselves!
B- I eliminated this one because it hints at the idea that the traveler's perceptions aren't accurate
C- I didn't understand the relevance of this answer choice so I quickly eliminated.
D- I picked this and this is my reasoning for it being incorrect: If accomplished non-native speakers didn't perceive sentences as streams of sounds, then this could add to the evidence that the perceptions of native speakers (and people who speak language correctly) is more correct than those who do not. However, if you negate this, then you get evidence that DOES seem to have to be assumed? I'm confused by this answer choice. According to the negation,
Accomplished non-natives DO perceive sentences in streams of sounds, and this gives credibility to the idea that native speakers are illusionary percepts...they seem to be the only ones who perceive sentences as separate words. Does this make the argument fall apart? I'm confused....
E- This is correct because it cannot be the case that the natives are more accurate. But I'm still unsatisfied. What if they are JUST as accurate? I guess I'm not used to assumption questions where the right answer doesn't make the argument bulletproof...
