Archaeological Evidence Has Been Used to Reintroduce Ancient Technology in Areas

Archaeological evidence has been used to reintroduce ancient technology in areas where it might be useful, such as in Andean farming communities. Results of these experiments indicate that:

A) ancient technology cannot be effectively employed because the social, political, and economic systems of the past were completely different from those of today.
B) ancient technology can be highly efficient and cost effective even in the modern world.
C) modern communities are skeptical of the benefits of ancient technology, and are thus unwilling to invest resources in what they consider to be outdated techniques.
D) archaeologists do not know enough ancient technologies to effectively implement them in the modern world.
