I want to know the answer to the following question:
What is the ratio of black and Asian schoolchildren to white schoolchildren?
All the background I'm provided with is that "In January 2005, a survey of London's ethnic and religious diversity claimed that there were more than 300 languages spoken in London and more than 50 non-indigenous communities with a population of more than 10,000.". Is that enough to answer the question?
Answer: no
