Hi all. Hope you are all having a great beginning of the week.<br/><br/>I came to wonder if there is any subtle difference when the preposition locates before relative pronoun. See the eg below;<br/><br/>A:Their pool in which kids can swim safely is 50 years old.<br/>B:Their pool which kids can swim in safely is 50 years old.<br/><br/>A:Imagine life is a game in which you are juggling five balls.<br/>B:Imagine life is a game which you are juggling five balls in.<br/><br/>A:I know the place in which i was grown up.<br/>B:I know the place which i was grown up in.<br/><br/>I tried to list as many example sentences as possible just in case some of them are incorrect.<br/><br/>Ok, my question was, if there is any nuance difference or usage difference btw A and B? <br/><br/>Thanks for your help in advance.
