а) Why haven't we emigrated? it we live in Italy, the weather id much better

Объяснение:

При "We, You,They" мы ставим всегда "Are"

При "He,She,It" мы ставим всегда "Is" погода это "оно" значит будет стоят "is".

Когда стоит "We,They,You" мы не ставим окончание "ing"

например

как можно делать: He is watching TV,They aren't watch TV
