正确答案是D，为什么不选A
CXD.P26444 Biometric access-control systems-those using finger-prints, voiceprints, etc., to regulate admittance to restricted areas-work by degrees of similarity, not by identity. After all, even the same finger will rarely leave exactly identical prints. Such systems can be adjusted to minimize refusals of access to legitimate access-seekers. Such adjustments, however, increase the likelihood of admitting impostors.
Which of the following conclusions is most strongly supported by the information?
A. If a biometric access-control system were made to work by identity, it would not produce any correct admittance decisions.
B. If a biometric access-control system reliably prevents impostors from being admitted, it will sometimes turn away legitimate access-seekers.
C. Biometric access-control systems are appropriate only in situations in which admittance of impostors is less of a problem than is mistaken refusal of access.
D. Nonbiometric access-control systems-based, for example, on numerical codes-are less likely than biometric ones to admit impostors.
E. Anyone choosing an access-control system should base the choice solely on the ratio of false refusals to false admittances.
