Historical questions- Needs to be Past Tense.
Example Topic: Global economic inequality and the climate crisis (too broad, narrow by geography and time period)
Non-historical question (AVOID!): What can be done to reduce wealth gaps and empower the people in developing nations to reduce their consumption of their natural resources and still become economically stable?
Historical question (BETTER) (too broadly conceived at this point, but note use of past tense): How did the European industrial revolution impact the economies and natural resources of non-European countries through the mechanisms of globalization?
Specific historical question (GREAT - refined after some initial research): How did the introduction of railroads in colonial British India impact local grain production and markets from 1870 to 1900?
