Reading the passage

A accepts testimony that examiners make mistakes extremely rarely. B questions the testing behind that confidence and ends with a more rigorous test that produced many errors. That's a real point of disagreement about reliability.

What we’re looking for

Check both sides of any proposed dispute. Mentioning a topic in only one account—or finding that both acknowledge the same fact—won't establish disagreement.

Working the answers

  • A

    A points to uniform standards developed through training as a reason for confidence. B criticizes the lack of objective standards. Neither position suggests opposition to uniform training; this isn't their dispute.

  • B
    Correct

    A's ending accepts an “exceedingly low error rate.” B argues that the rate is poorly studied, criticizes the reassuring tests, and reports a much worse result under stricter testing. They differ about how much confidence we should have that an examiner's identification is correct. B needn't supply a universal error percentage to challenge A's confidence.

  • C

    A acknowledges that fingerprint identification isn't scientific law. B doesn't argue over whether it should receive that status, so we lack opposing positions on this question.

  • D

    B mentions point counting and a holistic method, but A doesn't compare their relative merits. There is no two-sided dispute about which is better.

  • E

    Both acknowledge variation among agencies or local practices. A expressly concedes different degrees of correlation; B emphasizes varying requirements. They disagree about the significance of that variation, not whether it exists.
