Final answer:
The sentence should be corrected to option a) 'The old car with a flat tire was pulled down the street' for clarity and logical sentence structure.
Step-by-step explanation:
The correct rewrite of the sentence 'Old car was pulled down the street that had a flat tire' by correcting mistakes is 'a) The old car with a flat tire was pulled down the street'. This sentence clearly indicates that the old car had a flat tire and it was the one being pulled down the street, establishing a logical subject-verb-object order.
Option b) wrongly implies the flat tire pulled the car, which is illogical. Option c) uses an inverted sentence structure that is grammatically correct but less common. Option d) incorrectly suggests the street was pulled by the old car, which is nonsensical.
