b.Huang He
c.Ganges
d.Brahmaputra

Based on the available information, the main factor contributing to this river’s great sediment load must be ______. This factor is also evident in the sediment load, or amount of material suspended per cubic meter of water, in the Ching branch.

Table 11B-1 is a list of the major sediment-transporting rivers of the world along with their mean annual discharge (cubic meter per second), drainage area (thousands of square kilometer), mean annual sediment
transport (millions of tons per year), and sediment load (in kilogram per cubic meter). (For more on river locations with source and outflow information, see Link 11B-1.)
