Answer:
a workplace or factory where only members of the union were allowed to work.
Explanation:
A "closed shop" is a workplace or factory where only members of the union were allowed to work. They were powerful members of the factories who had the authority to demand uniform wages and standards to the owners.
During the time of protests and strikes by workers over workers' rights and standard wages, the union came into center stage. They could make strong demands and great influence over supply of labor. They helped in making the voice of the workers louder and heard to the capitalist owners.
The incans flourished from 1200 to 1535, until they were conquered by the Spanish conquistadors.
