Task: Question Answering
Input (English): Background Paragraph: You generally can’t see, smell, taste, hear, or feel radiation. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one pictured in the Figure below , contains atoms of a gas that is ionized if it encounters radiation. When this happens, the gas atoms change to ions that can carry an electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. 
Story: Marie is walking through the garbage dump when she spots two old drums that are used to store waste materials. Curious about what these drums contain, Marie reads the stickers on the side of each one. Drum P says "nuclear waste" on the side, and drum X says "sulfuric acid" on the side. 
Question: Which drum will cause a stronger reaction in a Geiger counter?
Output (English): Drum P.
