I was listening to McCain 's nomination acceptance speech on the radio on the way to the airport yesterday and it sounded so different than it did in the arena . I actually got to hear the fiery end to the speech , the part where he said : Stand up , stand up , stand up and fight . Nothing is inevitable here .
Why did the speech sound so different ?
- Because McCain was having trouble with his voice .
 - Because of the trouble with the microphone .
 - Because of the acoustics in the arena .
 - None of the above choices .


Because of the acoustics in the arena .
