Consider this sentence:
It seems likely that chunking is taking advantage of cues from prosody, the natural rhythms that occur in speech and that make its meaning clearer by separating into coherent phrases the continuous sequence of sounds that make up the normal speech stream.
Is "that" in "and that make its meaning clearer" viewed as a conjunction or viewed together with "and" as an informal grouping used to describe all sort of natural rhythms?
What does "that" in "that make up the normal speech stream" refer to? Is it "coherent phrases" or "sequence of sounds"?
