    Perfect. Those were the ones I'm talking about! :) Now let's look at those other options, shall we? Well, petrol - what is that used for, commonly? I can list a few... cars, airplanes.... Hmmm... Coal was commonly used to fuel trains, ships, and to keep people warm... Look at the time frame this question is speaking about. Which could be eliminated, coal or petrol?

    Are you sure? Maybe you could look at it again? Petrol is used for cars and airplanes. Coal is used for ships and trains. Which technology was more available in the 1800s?
