In the fourteenth and fifteenth centuries, many Western Pueblo
settlements in what is now the southwestern United States may have possessed
distinctly hierarchical organizational structures. These communities’
agricultural systems ―which were “intensive” in the use of labor rather than
“extensive” in area ―may have given rise to political leadership that managed
both labor and food resources. That formal management of food resources was
needed is suggested by the large
size of storage spaces located around some communal Great Kivas (underground
ceremonial chambers). Though no direct evidence exists that such spaces were
used to store food, Western Pueblo communities
lacking sufficient arable land to support their populations could have
preserved the necessary extra food, including imported foodstuffs, in such
apparently communal spaces.

Moreover, evidence of specialization in producing raw materials and in
manufacturing ceramics and textiles indicates differentiation of labor within and
between communities. The organizational and managerial demands of such
specialization strengthen the possibility that a decision making elite existed,
an elite whose control over labor, the use of community surpluses, and the
acquisition of imported goods would have led to a concentration of economic
resources in their own
hands. Evidence for differential distribution of wealth is found in burials of
the period: some include large quantities of pottery, jewelry, and other artifacts,
whereas others from the same sites lack any such materials.

According to the passage,
which of the following is probably true of the storage spaces mentioned in line
14?

A.
They were used by the
community elite for storage of their own food supplies.

B.      
They served a ceremonial
as well as a practical function.

C.
Their size is an
indication of the wealth of the particular community to which they belonged.

D.
Their existence proves
that the community to which they belonged imported large amounts of food.

E.      
They belonged to
and were used by the community as a whole.
