B) Between 500 and 1100 C.E., the highlands of Peru were home to a far-reaching empire known as the Wari. Like the Inca after them, the Wari managed to spread their culture over the vast distances and rugged terrain of the Andes Mountains. Now,new finds from a small site in Peru suggest the Wari may have a special way to    21    political alliances. That is, the Wari would serve   22   beer to local elites at periodic parties, extending their empire one trippy feast at a time.
    From the artifacts excavated near Arequipa in southern Peru, the outpost lacks any weapons that might signal a military presence. Then, how could a small group of foreigners so far from home get locals to accept them and perhaps even recognize their authority? Clues came from Quilcapampa's dry soil, which   23    hundreds of thousands of dried plant remains. After spending months sorting them, Dickinson College archaeobotanist Matthew Biwer found 16 seeds from a hallucinogenic jungle
plant called vilca.
    The vilca had been soaked and fermented,     24    to make a strong beer known as chicha. That suggests vilca was a controlled substance, says the researchers. Rather than organizing grand public ceremonies or military invasions, the Wari may have built their empire one party at a time. Artifacts from other Wari sites suggest they had a heady party culture: Much of their pottery is dedicated to beer brewing or serving. Because vilca was an exotic substance in Quilcapampa, a vilca-fueled party there
would have been special,    25    .the new arrivals' prestige.
