問題文
A data architect has put five match rules of one kind into a single match model for a manufacturer's vendor data. Two of the five carry exactly the same settings and differ in nothing but the criteria they are built on. The architect also wants to settle which merge strategy leaves a rule out of the sequence that the model works through rule by rule. Which pairing correctly states the merge strategy that keeps a rule out of that sequence, and what the two near-twin rules produce?

- The merge strategy that keeps a rule out of the sequence in which the rules are tried is the automated strategy, and two rules that agree on every property apart from the criteria they use end up with identical sets of matching rows.
- The merge strategy that keeps a rule out of the sequence in which the rules are tried is the threshold strategy, and two rules that agree on every property apart from the criteria they use end up with identical sets of matching rows.
- The merge strategy that keeps a rule out of the sequence in which the rules are tried is the automated strategy, and two rules that agree on every property apart from the criteria they use end up with divergent sets of matching rows.
