[单项选择]Archaeology has long been an accepted tool for studying prehistoric cultures. Relatively recently the same techniques have been systematically applied to studies of the more immediate past. This has been called "historical archaeology," a term that is used in the United States to refer to any archaeological investigation into North American sites that postdate the arrival of Europeans.
Back in the 1930’s and 1940’s, when building restoration was popular, historical archaeology was primarily a tool of architectural reconstruction. The role of archaeologists was to find the foundations of historic buildings and then take a back seat to architects.
The mania for reconstruction had largely subsided by the 1950’s and 1960’s. Most people entering historical archaeology during this period came out of university anthropology departments, where they had studied prehistoric cultures. They were, by training, social scientists not historians, and their work tended to reflect this bia

Maintaining internal e-mail systems has long been the bane of the university information-technology director. Servers are unwieldy and unreliable, and in the past several years, the number of student complaints has grown exponentially as forward-moving providers like YahooMail, Hotmail, and Gmail have increased expectations of what E-mail should offer.

At the University of Pennsylvania, its old E-mail service gave students 60 megabytes of storage, just 3 percent of the 2 gigabytes Windows Live now provi
A. University information-technology director refused to replace outdated e-mail systems with new ones.
