I want to know the answer to the following question:
From 1990 to 2010 what was improvement in piped water supply to urban areas?
All the background I'm provided with is that "Among the achievements are an increase of piped water supply between 1990 and 2010 from 89% to 100% in urban areas and from 39% to 93% in rural areas despite rapid population growth, the elimination of open defecation in rural areas during the same period, and in general a relatively high level of investment in infrastructure.". Is that enough to answer the question?
