Analyze the past participle of "run"
The past perfect construction "hadn't [verb]" requires the past participle form of the verb "run".
- Simple past: ran
- Past participle: run
Therefore, "hadn't run" is grammatically correct, while "hadn't ran" is incorrect.
Analyze the past participle of "fall"
The conditional perfect construction "wouldn't have [verb]" requires the past participle form of the verb "fall".
- Simple past: fell
- Past participle: fallen
Therefore, "wouldn't have fallen" is grammatically correct, while "wouldn't have fell" is incorrect.
Identify the correct sentence
Combining the correct past participle forms ("hadn't run" and "wouldn't have fallen") yields:
"If he hadn't run, he wouldn't have fallen."
