Answer:
What do you need help with on this sentence?
Explanation:
The correct answer to this question is the technological advancement of the television. Kennedy's presidential election was the first election where speeches could be broadcast by television.
The stylistic element used in the passage is incongruity. It is a form of satire or humor. Incongruity is used in an unsuitable time. For example, If a man were in a court room and belched loudly while receiving his sentence, that would be a use of incongruity. Another example would be if at a royal wedding the groom's pants fell down in the middle of the ceremony.
