9. The questions are not randomly ordered. They are clustered ingroups of perhaps ten questions that move from the earliestperiod through the twentieth century. That is, in every block often or so questions you will notice a progression from thePre-Columbian or colonial periods to the mid- to late twentiethcentury, and then in the next block, the questions will jumpback to the early period.
