Question

a dance group based in wales holds an annual seven - to ten - day public event. the group has staged the event in the united kingdom, ireland, and italy. each event begins with what seems to be an unplanned incident. a pair of workers wearing bright safety vests may start dancing together on the sidewalk. many of the people passing by are unaware they are viewing a professional performance. over the following days, more skilled dancers in ordinary clothing join the group. on the final day of the event, nearly one hundred dancers perform an exciting routine. at first, the dancing appears to be blank. options: frenzied, random, combative, ceremonial

Explanation:

The text says the event begins with what "seems to be an unplanned incident" and a pair of workers start dancing on the sidewalk. "Random" fits as it appears unplanned and without a set pattern initially, while "frenzied" implies chaos (not indicated), "combative" is about fighting (irrelevant), and "ceremonial" is formal (opposite of unplanned).

Answer:

B. random
