Final answer:
In Plato's story of the ring of Gyges, the ring indeed had the power to make one invisible, which is True.
Step-by-step explanation:
The answer to the question is 1) True. In Plato's story of the ring of Gyges, the ring did indeed have the power to make the wearer invisible. This story is part of the larger work called Republic, and it explores the concept of morality and the nature of justice.
In Plato's story of the ring of Gyges, the assertion that the ring had the power to make one invisible is True. This story is separate from the Allegory of the Cave, in which prisoners mistake shadows on a wall for reality, symbolizing the difference between the perception of appearances and the understanding of the forms of things. However, the student's question pertains to a different myth from Plato's works, where a shepherd named Gyges finds a ring that grants him the power of invisibility, thereby exploring the theme of morality when one's actions are unobserved.
