Task: Question Answering
Input (English): passage: One litre of liquid water has a mass of almost exactly one kilogram, because the kilogram was originally defined in 1795 as the mass of one cubic decimetre of water at the temperature of melting ice. Subsequent redefinitions of the metre and kilogram mean that this relationship is no longer exact.
 question: is 1 liter of water equal to 1 kg?
Output (English): Yes
