Question

engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next? a. collaborate with other engineers in the construction of a plane made from this metal. b. begin marketing this new technology to other engineers. c. test the planes safety features. d. collaborate with other engineers in the design of a plane made from this metal.

Explanation:

Before constructing a plane (Option A), testing safety features (Option C), or marketing (Option B), the logical first step is design. Designing a plane (Option D) using the new metal would come before construction, safety - feature testing (as you need a design to test), and marketing (since you need a viable design to market).

Answer:

D. Collaborate with other engineers in the design of a plane made from this metal.
