Composite materials are synthetic materials made by combining multiple materials that have differing chemical compositions, and the resultant material has chemical properties that differ significantly from those of any of the original materials and is stronger, less heavy, and less expensive than conventional materials. While composites have been commonly used throughout history to construct building materials, they are actually predated by natural composites such as shellac, which are cheaper than synthetic materials. Therefore, to minimize expenses, natural composites should be used whenever possible.
Which of the following would it be most useful to know in determining whether using natural composites would minimize expenses?
A. Whether some natural composites cost more than synthetic composites
B. Whether the long term costs of maintaining buildings made using natural composites is significantly higher than those made using synthetic composites
C. Whether some composites have properties that do not differ significantly from the properties of the base materials used to create the composite
D. Whether either natural or synthetic composite have used in markets other than the one for building materials
E. Whether there are any natural composites that predate shellac
