Which of the following best explains why townships are becoming sparser throughout the country today? a. due to the recession and high unemployment, people are leaving rural areas to find work in metropolitan areas. b. due to population growth in once-rural areas, counties are now replacing townships and providing the same services. c. due to plummeting commodity prices (wheat, corn, soy beans), populations of farmers in rural areas can no longer support themselves and have relocated to urban areas. d. since state tax revenues have fallen since the recession, states have had to cut funding to townships, forcing people who rely on government services to relocate in larger cities.
