I want to know the answer to the following question:
For how many years in a row has Melbourne held the top position in a survey of the world's most liveable cities?
All the background I'm provided with is that "For five years in a row (as of 2015) it has held the top position in a survey by The Economist Intelligence Unit of the world's most liveable cities on the basis of a number of attributes which include its broad cultural offerings.". Is that enough to answer the question?
Answer: yes
