Answer:
1. Some benefits of being in the EU are trade deals with other countries and we can get some amounts of money from them.
2. Being a member of the EU means that we have to give large amounts of money towards the EU every year.
3. I think the UK made this decision because we don't have to deposit large amounts of money towards the EU anymore; the UK can control their own water (English Channel) and only the UK can fish there.
