example one: A): I love the small town in which I lived during my childhood. B): I love the small town which I lived in during my childhood here, sentence A = sentence B (because "in which I lived" and "which I lived in" are interchangable. example two: C): This is the thread in which I enjoyed the most in this forum so far. D): This is the thread which I enjoyed in the most in this forum so far. here, both sentences are grammatically wrong because of "in". example three: E): This is the thread in which I wrote few words that were offensive. F): This is the thread which I worte in few words that were offensive. here, sentence E = sentence F (because "in which I wrote" and "which I wrote in" are interchangeble. 1): Kindly correct possible wrong-sentence-structure in the above sentences (if there is any). 2): Kindly explain what's wrong with "in" in sentence C and D (though I know it's wrong, but I don't know how to explain it). 3): Could you rewrite sentence E and F to make them more stand out! Your help is very much appreciated
