1		Humans developed almost all rosebushes sold today. Some roses might have very desirable characteristics, such as color, disease resistance, or flower size, but they do not grow well because they have very weak root systems. Other rose plants have very strong roots but bloom poorly. So buds from the attractive roses are grafted onto the healthy roots of another bush. The rosebush that results has all the good qualities of both plants. Which of the following statements best summarizes the information in the above paragraph?
			A)	Today’s rosebushes have shallow roots.
			B)	Today’s rosebushes are resistant to disease.
			C)	Rosebushes available today have a strong root system but lack appealing color and flower size.
			D)	Most of today’s commercially available rosebushes are grafted plants and have characteristics of beauty and color as well as a strong root system.
			E)	Nearly all rosebushes do not grow well.
