Final answer:
The word that best replaces 'dilapidated' without changing the meaning is 'run-down'.
Step-by-step explanation:
The word that best replaces the word 'dilapidated' without changing the overall meaning of the passage is 'run-down'. Both words convey the idea that the building is in a state of disrepair and in need of renovation. 'Repaired', 'rebuilt', and 'renovated' all imply that the building has been fixed or improved, which would change the meaning of the passage. Therefore, 'run-down' is the best alternative.
