The following passage is adapted from an archaeological study of ancient trade networks. Based on the context of the passage, what is the correct form of the noun 'vessel' that should fill the blank?
Answer:To construct a precise chronology of the region's ancient trade networks, archaeologists analyzed the chemical composition of several newly excavated clay vessels. By identifying the unique trace elements in the clay, the researchers concluded that the pottery's distinct mineral signature could reliably trace each 【vessel's】 origin to a single, localized kiln in the river valley.
Answer
vessel's
The correct answer is the singular possessive form 'vessel's'. The word is preceded by the singular determiner 'each', which requires a singular noun rather than a plural one. Furthermore, the noun modifies 'origin', meaning it must be in the possessive case to show the relationship between the vessel and its origin.
