OK

1) What is a common disadvantage of switching to clean fuels for vehicles?

A higher cost for vehicles and fuel.

OK

2) What is the most overwhelming common advantage of switching to clean fuels?

It decreases in air pollution and using it would decrease our dependancy on imported oils.

OK

3) Does this article really answer whether clean fuels are feasible?

Well, there is a paragraph dedicated to the question. Isn't feasibility an opinion. I assume that if everybody, or a good majority decided it was the better thing to do then it would happen. And that is kind of what the paragraph mentions.

OK

4) List the fuels on the Comparison chart by octane rating, from lowest to highest:

Electricity No. 2 Diesel, Biodiesel(B20), Gasoline, Ethanol(E85) and Methanol (M85), Liquified Petroleum Gas (LPG), Compressed Natural Gas(CNG) and Liquified Natural Gas (LNG), and Hydrogen.

OK

5) Which alternative fuel has the most diversity to date for types of vehicles?

Ethanol (E85)

OK

6) Rank the all the fuels on the chart by their energy content from highest to lowest:

No. 2 Diesel, Biodiesel, Gasoline, LPG, Ethanol (E85), LNG, Methanol (M85), and CNG Electricity and Hydrogen

OK

7) Gaging by the chart, what seems to be the safest fuel?

Hydrogen

OK

8) Do you have any way of gaging whether this chart was accurate or not? How would you go about finding out if it is true or not?

No, I guess if I learned more about the subject and did extensive research I would find my own answers, perhaps even their answers. They can't possibly know EVERYTHING about the fuels or the future affect of using these fuels.
