Here are the mistakes: 1. The film who -> The film that (or which) - 'who' is used for people, 'that' or 'which' for things. 2. I like that shirt whom -> I like that shirt which - 'whom' is the object of a verb, 'which' is used for things. 3. The only house to be paint -> The only house to be painted - missing 'ed' in the verb. 4. Do you get on with the person which -> Do you get on with the person who - 'who' is used for people. 5. A dictionary is a book whom -> A dictionary is a book that - 'whom' is the object of a verb, 'that' is used for things. 6. He is the most handsome boy whose -> He is the most handsome boy I have ever met - 'whose' is not necessary here. Alternative: He is the most handsome boy who I have ever met - 'who' is used for people. 7. I can't speak English, whom -> I can't speak English, which - 'whom' is the object of a verb, 'which' is used for things, or better: English is not my strong point. Alternative: Not speaking English is a disadvantage. 8. The policeman must try to catch those people whom -> The policeman must try to catch those people who - 'who' is used for people. 9. The man about who -> The man I told you about - 'about' is not used with 'whom' like this, instead use 'about' without 'who'. Alternative: The man whom I told you about - formal, or 'The man I was telling you about'. 10. Father's Day is the day where -> Father's Day is the day when - 'when' is used for specific times. 11. Do you know the reason when -> Do you know the reason why - 'why' is used for asking about reasons or explanations. 12. The man whose -> The man who - 'whose' is a possessive pronoun, use 'who' to refer to the subject of the clause.
