CRM survey projects differ from research survey projects in that:
a. More volunteers and students are usually present on CRM survey projects, and so
these projects tend to move more slowly than research survey projects.
b. In CRM, the research question determines the survey area.
c. In CRM, the size and nature of the development project largely determines the survey
area.
d. If sites are located on CRM survey projects, investigators do not need to determine
their significance.
Archaeologists prefer to dig in arbitrary rather than natural levels whenever possible to
reduce the risk of mixing artifacts from different strata.
Tree ring dating is possible because:
a. Variable tree ring widths preserve information about past climatic change and can be
fit into a long-term chronological sequence.
b. Tree rings can simply be counted and subtracted from the present to determine the
calendar date of the tree’s death.
c. All trees respond to climatic variability in the same way.
d. All of the above.
