Which statement best describes the reason technology changes over time?

• People enjoy having new technology.

• Old technology never meets the needs it was designed for.

• People’s needs are better met when technology is very complex.

• People find better ways to meet their needs as their knowledge increases.

What is the first step an engineer should take in developing a new technology?

• Identify the problem to be solved.

• Test the model of the new machine.

• Design the model for the new machine.

• Evaluate the performance of the machine.

How is failure part of the design process?

• Once a prototype fails, the process has ended.

• Failure is not part of the design process.

• Failure convinces engineers to give up.

• Failure can reveal areas that need improvement.

Which is the best reason for sketching or drawing a design before constructing it?

• Once constructed, a design cannot be changed at all.

• A functioning design is not as interesting as a sketch.

• Certain design improvements can be made more easily in a sketch.

• Sketching reflects the design’s function in the real world without error.
