A new bus has built-in GPS technology. What problem does GPS technology solve?

• Passengers and drivers may be injured in an accident

• Some vehicles cannot hold enough people

• Some vehicles do not travel fast enough

• The bus driver might get lost

What is the first step in the design process?

• do research

• develop possible solutions

• identify the problem

• test a prototype

An engineer is developing a new design for a tram. The engineer has 3 designs to choose from. Which design should the engineer select?

• the quickest one to produce

• the most costly one to make

• the smallest one

• the one that meets the most important needs

What is the main purpose of developing a prototype?

• to see how the product will look

• to figure out how much the product will cost to build

• to test whether or not the product will work

• to find out if people like the product
