Now seems like a good time to post this Cultural Literacy worksheet on the green revolution. This is a half-page worksheet with a reading of two longish sentences and three comprehension questions.
For the record, this document deals with the increase in the 1960s and 1970s in the production of cereals like wheat and rice due to advances in the productivity in seeds and innovations in agricultural technology, and not any kind of political revolution.
