Essay:
1. Increases farm income, boosts employment, improves balance
of trade, adds to tax receipts, results in a net savings to the
federal government, less dependence on foreign oil.
2. The increase in corn prices are offset by the production of
cattle feed during the making of ethanol. While it is possible
that meat & milk prices might increase slightly, it is doubtful.
Module 4: Environment
Matching:
1. D 2. B 3. E 4. C 5. F
Essay:
1. Ethanol and other oxygenated fuels take the place of some of
the gasoline and adds oxygen to the combustion process which
reduces levels of all pollutants controlled by the EPA.

1. ETHANOL 12. OXYGEN
2. OCTANE 13. SUBSIDY
3. GASOLINE 14. OIL
4. CARBON MONOXIDE 15. DEHYDRATE
5. EMISSIONS 16. BRAZIL
6. GRAIN 17. FARMER
7. CORN 18. FUEL
8. ALCOHOL 19. HYDROCARBONS
9. OZONE 20. UNLEADED
10. ENERGY 21. INCENTIVE

Module 5: The Fuel
True / False:
1. Fuel extender 6. 85%
2. Octane booster 7. Brazil
3. True 8. True
4. 40% 9. Ethanol
5. True 10. True
Multiple Choice:
1. C 2. E 3. B 4. B 5. A
Fill in the Blank:
1. gasoline 6. 90
2. octane rating 7. methanol
3. pinging or knocking 8. 17%
4. volatility 9. 100%
5. 9 10. variable
Essay:
1. Ignition timing, air fuel ratio, barometric pressure,
temperature, humidity, combustion temperature, exhaust
gas re-circulation rate, combustion chamber deposits.
2. Volatility too low causes: poor cold start, poor warm-up
performance, poor cool weather driveability, increased
crankcase, combustion chamber & spark plug deposits,
or unequal fuel distribution.
Volatility too high causes: vapor lock, loss of power, rough
running or stalling, decreased fuel mileage, increased
evaporative emissions, or fuel evaporation canister overload.
3. Reduced emission levels, especially hydrocarbons & carbon
monoxide (use of ethanol made from corn increases amounts
of corn grown which increases the conversion of carbon
dioxide into oxygen, which combats global warming).
