Tom has three sister. All of them are married.
Is it correct to rewrite like this: 'Tom has three sister, all of whom are married.' ?
One more question: Can these two sentences
That car belongs to Dr.Clark. Its engine is very good.
be rewritten like this: 'Dr.Clark has a car the engine of which is very good' ?
As a ready check in such sentences, simply substitute the personal pronoun “he/him”, “she/her” or “they/them” for “who/whom.”, it/that for ‘which’. If he. She or they would be the correct form, the proper choice is who.” If “him”, “her” or ’them’ would be correct, use “whom.” In case of which use 'it' or 'that' to find the correct form.
'Tom has three sister, all of whom are married. (All of them/(they) are married)
'Dr.Clark has a car the engine of which is very good' (The engine of that/(it) is very good.)
