Dishwashers and dryers are new technologies. Which is a way that these appliances changed people's lives?

• they make dishes and clothes last longer
• they never break, so people do not have to worry about them
• they make chores take longer because these appliances must be watched
• they make these chores take less time, which lets people do other things

Which is NOT a step in the engineering process?

• Design your solution
• Test your prototype
• Make a perfect prototype
• Define the problem
