Concept:The passage describes the goldsmith’s work using religious imagery through direct and indirect comparisons.Explanation:The goldsmith is directly called “a priest at the altar.”This direct comparison without “like” or “as” is a metaphor.The phrase “as though he were performing the Eucharist” uses “as though” to make a comparison.The rings are called “like miniature wafers,” using “like” to compare two different things.Comparisons using “like” or “as” are similes.Therefore, the dominant literary devices are metaphor and simile.Answer:C. metaphor and simile
