[{"role": "user", "content": "I'm trying to learn Italian and I stumbled upon the sentence 'Who did this to you?' and I'm having trouble translating it. Can you help me find the correct Italian translation?"}, {"role": "assistant", "content": "The correct Italian translation for 'Who did this to you?' is 'Chi ti ha fatto questo?' or more formally 'Chi le ha fatto questo?' depending on the level of formality you want to use. The 'le' in 'Chi le ha fatto questo?' is a formal way to say 'to you', whereas 'ti' in 'Chi ti ha fatto questo?' is more informal."}]
