Many English writers and thinkers in the eighteenth century felt that the English language should be standardized. Which social
change was most closely related to the perceived need for standardization? 1-growth of the urban population
2-religious reforms
3-increased life expectancy
4-increased literacy
5-relaxation of censorship laws
