Final answer:
In the guild system, an individual worked for no wages during the apprenticeship phase. They were provided with food and lodging but did not receive monetary compensation until they advanced to journeyman status.
Step-by-step explanation:
At which point in the guild system did a person work for no wages? The correct answer is a) Apprentice. During their time as apprentices, individuals in the medieval guild system received no wages. They worked under the guidance and supervision of a master to learn the craft or trade. As part of their training, apprentices were provided with food, lodging, and education, but not monetary compensation. It was only after progressing through the apprenticeship and achieving the status of journeyman that they began to earn wages. Additionally, becoming a master was even more challenging since guild rules could be restrictive, often only allowing sons and sons-in-law of current masters to reach that level.
