Task: Question Generation
Input (English): Background Paragraph: Soil is well developed in the forest as suggested by the thick humus layers, rich diversity of large trees and animals that live there. In forests, precipitation exceeds evapotranspiration which results in an excess of water that percolates downward through the soil layers. Slow rates of decomposition leads to large amounts of fulvic acid, greatly enhancing chemical weathering. The downward percolation, in conjunction with chemical weathering leaches magnesium (Mg), iron (Fe), and aluminum (Al) from the soil and transports them downward, a process known as podzolization. This process leads to marked contrasts in the appearance and chemistry of the soil layers. 
Story: Brad and Frank are two cousins. they both own land in the same county. Frank's parcel is a pine forest, while Brad's is a nice dry grassland with wild flowers and  a few shrubs.
Output (English): Which parcel has an excess of water that percolates downward through the soil layers?
