Task: Question Generation
Input (English): Passage: The poverty line in the UK is commonly defined as being 60% of the median household income. In 2007-2008, this was calculated to be £115 per week for single adults with no dependent children; £199 per week for couples with no dependent children; £195 per week for single adults with two dependent children under 14; and £279 per week for couples with two dependent children under 14. In 2007-2008, 13.5 million people, or 22% of the population, lived below this line. This is a higher level of relative poverty than all but four other EU members. In the same year, 4.0 million children, 31% of the total, lived in households below the poverty line, after housing costs were taken into account. This is a decrease of 400,000 children since 1998-1999.
Output (English): How many children, in percentage, did NOT live in households that were below the poverty line, after housing costs were taken into account, in the year of 2007-2008?
