Final answer:
The sentence that should be revised for clarity in the passage is sentence (6). After the war, some places in the United States switched back to standard time, while others continued with daylight saving time.
Step-by-step explanation:
The sentence in the passage that should be revised for clarity is sentence (6): some places in the United States went back to standard time after the war, but others Repedaylight saving time.
This sentence is unclear and appears to have a typographical error with the word 'Repedaylight'.
A revised and clearer version of the sentence could be: After the war, some places in the United States switched back to standard time, while others continued with daylight saving time.
