Open Word and answer the following questions. Save the document and print it when you are done.
1. Sometimes a best-practice investment is quickly leapfrogged by newer technology. Google “fiber optic overinvestment” to see an example. Briefly describe what happened and cite the web sources used.
2. Automobile emissions requirements are stricter in Japan than in the United States (where many areas have no vehicle inspection at all). In both countries, newer cars pass inspection (if required) easily, but older cars are more likely to fail inspection and be removed from the operating car fleet. Draw hypothetical Salter Graphs, with emissions on the y axis, for the car fleets of Japan and the United States that reflect the stricter emissions standards in Japan.
3. What happens to a late model year Toyota or Honda that has failed an emissions inspection in Japan and, therefore, cannot be used there? Google “japan used engines” to find out. What effect does this have on the U.S. Salter Graph that you drew earlier?
4. The National Highway and Traffic Safety Administration maintains a database of car characteristics by model year. For miles per gallon (MPG) performance, they show the following:
These data cannot be used to show a Salter Graph (with MPG on y axis) of the U.S. car fleet. Why not? What additional information is needed?
