According to NAGPRA, museums must return specific skeletons, sacred objects, and
funerary goods to Native American groups if
a) they ask for them
b) they can no longer afford to store the objects
c) if the Native American group promises to preserve and conserve the remains
d) if cultural affiliation linking the goods to the modern group can be shown
e) if the objects were found to have been removed from native land before 1900 without

The long-term study of an earthwork constructed at Overton Down, England, as
experimental archaeology indicates that
a) preservation was better in the chalk bank, and preservation of leather and pottery was
unchanged after 4 years
b) preservation was superior in the turf core, and preservation of textiles and other
organic material had changed little after 4 years
c) preservation was quite poor regardless of whether artifacts were in chalk or turf,
primarily because of rodent and earthworm activity
d) archaeologists have been underestimating the effects of earthworm activity on
preservation and site formation processes
