Explanation:

First Sentence (The scientists did an experiment to ____ speech using brain waves for listening.)

To determine the correct word, we analyze the context. The experiment is related to speech and brain waves for listening. The word "listen to" makes sense here as the scientists are doing an experiment to listen to speech using brain waves. So the first blank is filled with "listen to".

Second Sentence (The scientists asked volunteers to __ a series of __.)

For the first blank in this sentence, we consider the action the scientists asked volunteers to do. "Produce" fits as in producing speech (or related to the experiment). For the second blank, "words" makes sense as volunteers would produce a series of words. So the first blank is "produce" and the second is "words".

Third Sentence (The patterns of the volunteers' ____ were recorded while they listened.)

The context is about recording patterns related to volunteers and listening. "Brain waves" are what would have patterns recorded during listening, so this blank is filled with "brain waves".

Filled Sentences:

1. The scientists did an experiment to listen to speech using brain waves for listening.
2. The scientists asked volunteers to produce a series of words.
3. The patterns of the volunteers' brain waves were recorded while they listened.

Answer:

s for each blank (in order of the blanks):

1. listen to
2. produce; words
