Question

engineers are looking for a new material to build the body of an airplane. they agree that the material must be lightweight, but also strong and long - lasting. above all, the material must maximize the safety of the passengers. several engineers have developed some initial plans. which stage of technological design is described in this passage? identify a problem. design a solution. implement a solution. evaluate the solution.

Explanation:

The passage describes engineers looking for a new material for an airplane body with specific requirements (lightweight, strong, long - lasting, safety) and having developed initial plans. This is the stage of designing a solution as they are coming up with ideas (initial plans) to meet the identified needs (material requirements).

Answer:

Design a solution.
