问题     Passwords are a pain in the ass. They’re either easy to【C1】______ or hard to remember, and when breaches (破坏)【C2】______ you have to come up with a whole new one. So people are trying to do away with passwords altogether, and so far fingerprint scanners are doing the job nicely.
    Still, fingerprints alone are not【C3】______ . Online security has become【C4】______ important, forcing service providers to come up with better measures such as two-factor authentication (验证) to【C5】______ user information. Companies are turning to other parts of our bodies to find biometric (生物计量的)【C6】______ that are up to the task, and our faces and eyes are at the top of the list. Although facial and eye-based recognition appear gimmicky for now, they may soon become as prevalent and popular as fingerprint scanners. That pairing could root out passwords and clunky text-message two-factor【C7】______ altogether, making it a completely biometric process.
    The popularity, prevalence and convenience of fingerprint scanning means it is here to stay, and by no means are face and eye recognition meant to【C8】______ it. Choudhury sees the newer method as a complement to fingerprints, providing a more convenient second-factor authentication as opposed to entering a text code sent to your phone. While the tech we have right now may not be fast or secure enough to be truly convenient and helpful, we’re getting close. Using the adoption of fingerprint scanners as a【C9】______ , Choudhury estimated we are about five years away from iris (虹膜) scanners and face detection becoming【C10】______ . Until then, we’ll have to deal with changing our crappy passwords every so often and hope we don’t forget them.
A) complements I) interfere
B) conceptions J) model
C) crack K) occur
D) defend L) replace
E) enough M) traditionally
F) identify N) verification
G) inappropriate O) widespread H) increasingly

选项
答案E
解析 空格在系动词are之后，因此空格处需要填入形容词作表语。上文提到“人们正努力彻底摆脱密码，到目前为止，指纹识别器在这方面做得非常好”，本句接着指出“只有指纹还不______”，由句首的Still“然而”可推测，本句和上文之间是转折关系，并且空格后一句中提到还需要提供更好的措施。由此可知，E)enough“足够的，充足的”为答案。
