SAT English Practice Question

The following text is adapted from a 19th-century travelogue by explorer Richard Francis Burton. Burton writes about his travels across Africa, describing the inhabitants and landscapes that he encounters. "A great deal of the country is mere swamp, or what is known as the *sudd*. This is a mass of vegetation, chiefly papyrus reeds, growing so thickly that it is almost impossible to penetrate it. The *sudd* is so dense and widespread that it forms a network of channels through which navigation is slow and dangerous. I am told that it is difficult to clear it, as the dense reeds are of a very tenacious quality."
