ответ:

sincebecause any it did you visit should not hasn't ever traveled shouldn't have you sent they went may is cooking

объяснение:

конструкция has lived here времени present perfect говорит о действии, которое началось когда-то в прошлом, но продолжается и сейчас. значит, карен жила здесь с какого-то года.когда акцент направлен на причину, то используется слово because.когда мы говорим об отсутствии предмета, используется any.речь о погоде. значит, it.нужно что-то в past simple. did you visit идеально подходит.
