For each of the incomplete arguments in the left column, select the missing premise from the right column that, if assumed, allows the argument's conclusion to be properly drawn.
- Any coin minted with Laurion lead-silver isotope ratios was produced during the Athenian maritime hegemony. The hoard excavated at Sounion contains only coins that carry owl iconographic stamps. Therefore, the coins in the Sounion hoard were produced during the Athenian maritime hegemony.Every coin carrying an owl iconographic stamp is minted with Laurion lead-silver isotope ratios.
- Any planetary body exhibiting atmospheric phosphine in chemical disequilibrium without volcanic sulfur dioxide undergoes active biochemical methanogenesis. Spectroscopic scans of exoplanet Kepler-186f reveal significant atmospheric phosphine in chemical disequilibrium. Thus, Kepler-186f undergoes active biochemical methanogenesis.Exoplanet Kepler-186f is entirely free of atmospheric volcanic sulfur dioxide.
- Any subterranean aquifer with rapid conduit-dominated flow paths fails to filter microplastic particulates. Subterranean aquifers situated in dolomitic karst bedrock invariably feature rapid conduit-dominated flow paths. Hence, municipal wells drawing from the Edwards reservoir cannot produce water free of microplastics.All municipal wells drawing from the Edwards reservoir tap aquifers situated in dolomitic karst bedrock.
Answer
Argument 1 matches with the statement that all owl-stamped coins have Laurion isotope ratios; Argument 2 matches with the statement that Kepler-186f lacks atmospheric volcanic sulfur dioxide; Argument 3 matches with the statement that Edwards reservoir wells draw from aquifers in dolomitic karst bedrock.
Each correctly matched premise supplies the precise missing link needed to complete a valid deductive chain: connecting the subject of the premise to the sufficient condition of the governing rule.
