Dublin and Belfast are the two biggest cities on which island?

what a beautiful Belfast city is the people are so friendly and a nice pint of Guinness is one of the best you can drink. and a 100 miles from Belfast is Dublin just like Belfast you can injoy your time and holiday

I'm fairly sure that there are no big cities on Madagascar. Don't they teach geography in schools now?
