Select the sentence or pair of sentences that shows wordiness. Africa's rainforests are home to a vast variety of medicinal plants. Some of these plants are so rare that they are only found in these rainforests. These plants have very distinct health benefits that are difficult, but not impossible, to replicate. The herbal medicine industry relies on resources from the African rainforests for a majority of their raw materials. However, sometimes extracting these plants can be too difficult to be worthwhile. To avoid the difficulty of extracting these rare plants, people may look for substitutes for these rare plants that they can use instead. African rainforests are also home to a number of exotic animals that are not found in other parts of the world. These animals would not be able to survive in another location because they are so precisely adapted to their natural habitat.
