Native speakers perceive sentences of their own language as sequences of separate words. But this perception is an illusion. This is shown by the fact that travelers who do not know a local language hear an unintelligible, uninterrupted stream of sound, not sentences with distinct words.
Which one of the following is an assumption on which the argument depends?
(A) It is impossible to understand sentences if they are in fact uninterrupted streams of sound.
(B) Those who do not know a language cannot hear the way speech in that language actually sounds.
(C) People pay less close attention to the way their own language sounds than they do to the way an unfamiliar language sounds.
(D) Accomplished non-native speakers of a language do not perceive sentences as streams of sound.
(E) Native speakers' perceptions of their own language are not more accurate than are the perceptions of persons who do not know that language.

Conclusion:
Native speakers’ perception that speech is made of separate words is an illusion.
Evidence:
Non-native speakers hear the same speech as an uninterrupted sound stream.
Pre-thinking (gap in argument):
The argument assumes that:
Option check:
A) Impossibility of understanding continuous sound
→ Not needed; irrelevant to illusion claim → eliminate
B) Non-speakers cannot hear actual sound correctly
→ Too strong, and not required → eliminate
C) Attention difference in listening
→ Not about truth/accuracy → eliminate
D) Accomplished non-native speakers perception
→ Not central comparison → eliminate
E) Native speakers are not more accurate than non-speakers
→ Required assumption to treat native perception as “illusion” based on outsider experience → Correct
Native speakers’ perception that speech is made of separate words is an illusion.
Evidence:
Non-native speakers hear the same speech as an uninterrupted sound stream.
Pre-thinking (gap in argument):
The argument assumes that:
- Non-native perception is more “reality-like” or at least equally valid.
- Otherwise, we cannot conclude native perception is an illusion just because non-natives perceive differently.

Native speakers perceive sentences of their own language as sequences of separate words. But this perception is an illusion. This is shown by the fact that travelers who do not know a local language hear an unintelligible, uninterrupted stream of sound, not sentences with distinct words.
Which one of the following is an assumption on which the argument depends?
The argument says native speakers are mistaken because non-speakers hear the language as one uninterrupted stream. The key assumption is that non-speakers’ perception is not less accurate than native speakers’ perception. Otherwise, the evidence from travelers would not prove that native speakers are experiencing an illusion.
(A) It is impossible to understand sentences if they are in fact uninterrupted streams of sound.
This is not required. The argument is about whether words are perceived as separate in the sound stream, not whether uninterrupted speech can be understood.
(B) Those who do not know a language cannot hear the way speech in that language actually sounds.
This weakens the argument. If non-speakers cannot hear the speech accurately, their perception gives no reason to doubt native speakers’ perception.
(C) People pay less close attention to the way their own language sounds than they do to the way an unfamiliar language sounds.
This is not required. The argument does not depend on differences in attention.
(D) Accomplished non-native speakers of a language do not perceive sentences as streams of sound.
This does not help. The argument is based on travelers who do not know the local language, not accomplished non-native speakers.
(E) Native speakers' perceptions of their own language are not more accurate than are the perceptions of persons who do not know that language.
This is correct. If native speakers’ perceptions are more accurate, then the travelers’ perception of an uninterrupted stream would not show that native speakers are mistaken. The argument depends on denying that native speakers have a more accurate perception here.
