  12. A few questions We looked at storage, electronic and communication technology. What other technologies are undergoing dramatic improvement? If the first cars got only 1 mile per gallon, and that doubled every two years, what would our mileage have been 20 years later? Thirty years later?

  13. What is punched in this card?
