The largest urban area by far is the Greater London Urban Area with 9 million inhabitants. Other major populations centres include Greater Manchester Urban Area (2.4 million), West Midlands conurbation (2.4 million), West Yorkshire Urban Area (1.6 million) in England, Greater Glasgow (1.2 million) in Scotland and Greater Dublin Area (1.1 million) in Ireland.[citation needed]
What percentage of the population does England have compared to the other areas in the British Isles?

The problem: Answer a question about this article:
Uranium metal reacts with almost all non-metal elements (with an exception of the noble gases) and their compounds, with reactivity increasing with temperature. Hydrochloric and nitric acids dissolve uranium, but non-oxidizing acids other than hydrochloric acid attack the element very slowly. When finely divided, it can react with cold water; in air, uranium metal becomes coated with a dark layer of uranium oxide. Uranium in ores is extracted chemically and converted into uranium dioxide or other chemical forms usable in industry.
What reacts with finely divided uranium?
****
The answer:
cold water
