Answer: Based on the comparison between the poem "Birthright" and the painting American Progress, the advantage that the text medium has over the visual art medium is that it is better able to express a person's specific thoughts. While the painting can depict a scene or convey a general idea, it is not able to provide the same level of detail and specificity that the written word can. The poem "Birthright" is able to delve into the speaker's personal thoughts and emotions in a way that the painting cannot. Additionally, the text medium can use language and literary devices to convey complex ideas and themes in a way that a visual art medium may not be able to achieve.
