Thomas found no data at Gatecliff rockshelter in Nevada because:
a. The rockshelter had never been occupied by prehistoric populations.
b. Archaeologists do not excavate data; they excavate objects that must then be observed to produce data.
c. The site had been extensively looted prior to Thomas's investigations, and very little of it remained.
d. A major flood had eroded the rockshelter sediments, and all the artifacts contained within the sediments, prior to Thomas's investigations.
e. He was not looking for data, merely the interior measurements of the rockshelter with which to compare with other rockshelters in the area.
Question 2
An example of a high-level theory would be a theory that seeks to answer which of the following questions?

b. Why do we believe that this stone tool was used to process plant material rather than to butcher an animal?
c. Why did some societies evolve stratified social and political systems whereas others remained egalitarian?
d. How many artifacts are clustered around this hearth or fire pit?
e. How was this stone tool used to process plant material, not butcher an animal?
