Task: Question Generation
Input (English): Background Paragraph: Robert Boyle (1627-1691), an English chemist, is widely considered to be one of the founders of the modern experimental science of chemistry. He discovered that doubling the pressure of an enclosed sample of gas while keeping its temperature constant caused the volume of the gas to be reduced by half. Boyle’s law states that the volume of a given mass of gas varies inversely with the pressure when the temperature is kept constant. An inverse relationship is described in this way. As one variable increases in value, the other variable decreases. 
Story: Brian has two identical containers of the same gas sitting on his kitchen table. He has a device that allows him to increase the pressure of any container he wants. He brings the device up to container B but decides not to use it. He then goes over to container A and activates the device to increase the pressure.
Output (English): Which container's gas has less volume?
