Create an outline of this passage from the article, "A Profitable Business." Sheep raisers will cite advantages of raising sheep over other types of livestock. One of the advantages is that sheep are one of the few farm animals that produce two crops a year, lambs and wool. In addition, sheep are excellent weed destroyers and eat a greater variety of plants than do other types of livestock. Sheep are thrifty grazers and will eat ninety percent of the common weeds in the pastureland. Cows will eat only fifty percent of such weeds. Therefore, sheep can graze on range plants not eaten by other animals and utilize acres of wasteland not suitable for cattle grazing.
