2. What does the professor imply about the fuels used for manufacturing iron?
Iron could be produced faster using wood as fuel than using coal.

Coal was not always considered the best fuel for iron production.
Coal was imported to Britain because its coal mines were depleted.
3. What does the expression “ghost acreage from coal” refer to?
The amount of land used for coal production
The amount of land needed to produce enough wood to replace coal as an energy source

6. What does the professor think is one benefit of using the concept of ghost acreage in the discussion of British industrialization?
It provides a good indication of the degree of Britain’s dependence on international trade.
It enables accurate calculations of the amount of coal that was acquired by Britain through trade.
It allows accurate measurements of how much land was used to grow certain crops.
It allows researchers to determine how land was actually used during industrialization.
