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. test the planes safety features.
b. collaborate with other engineers in the design of a plane made from this metal.
c. collaborate with other engineers in the construction of a plane made from this metal.
d. begin marketing this new technology to other engineers.

Explanation:

Before constructing (C) or marketing (D), design (B) is a necessary step. Testing safety features (A) is relevant later in the process after design and construction. Designing a plane with the new metal (B) logically follows after identifying the material's benefits as it lays the ground - work for construction and further development.

Answer:

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