Which of the following illustrates the need for materials engineers to study different materials? Materials engineers can find new methods to combine or process different materials by researching the properties of individual substances.

Materials engineers need to be aware that ceramic, wood, and plastic, though useful for most prototypes, do not fit the needs of all designs.

Materials engineers should continually develop materials that are 100% natural and eco-friendly, when possible, to increase sustainability.

Materials engineers need to research different materials because they can eventually lead to compound materials, which are essential to the design process.
