问题        Face masks are one of the best defenses against the spread of COVID-19, but their growing adoption is having a second, unintended effect：breaking facial recognition algorithms(算法).
       Wearing face masks that adequately cover the mouth and nose causes the error rate of some of the most widely used facial recognition algorithms to rise to between 5 percent and 50 percent, a study by the US National Institute of Standards and Technology (NIST) has found. Black masks were more likely to cause errors than blue masks, and the more of the nose covered by the mask, the harder the algorithms found it to identify the face.
       "We need to understand how face recognition technology deals with masked faces," said the author of the report and NIST computer scientist. "We have begun by focusing on how an algorithm developed before the pandemic (大流行病) might be affected by subjects wearing face masks. Later this summer, we plan to test the accuracy of algorithms that were intentionally developed with masked faces in mind. "
       Facial recognition algorithms such as those tested by NIST work by measuring the distances between features in a target’s face. Masks reduce the accuracy of these algorithms by removing most of these features, although some still remain. This is slightly different from how facial recognition works on iPhones, for example, which use depth sensors for extra security, ensuring that the algorithms can’t be fooled by showing the camera a picture (a danger that is not present in the scenarios NIST is concerned with).
       Comment 1：
       Well, that’s one good thing to come out of the pandemic. Mass surveillance is nonsense. Time to pair masks up with sunglasses to deliver the decisive stroke.
       Comment 2：
       "Wearing face masks that adequately cover the mouth and nose causes the error rate of some of the most widely used facial recognition algorithms to rise sharply" Rubbish technology! I would’ve never guessed.
       Comment 3：
       There’s a reason why some country is already using gait(步态) analysis. Facial recognition is too easy to block or to fool.
       Comment 4：
       Pretty soon they are going to do…analysis. With the development of AI, there will be a way out.
       Comment 5：
       The AI’s getting better, though, so soon it won’t matter. Just like how you can pick out a relative or close friend even in bad CCTV footage, so too can AI. Your height, walking gait, mannerisms, voice, ears, clothing, etc, all add up to YOU.
Comment 1 seems to be__________.
选项 A、in favor of the rules for wearing face masks
B、in favor of the facial recognition technology
C、against the wide use of facial recognition
D、against the requirements for wearing face masks
答案A
解析 根据评论1“Well, that’s one good thing to come out of the pandemic. Mass surveillances…”即“好吧，这是大流行病过后的一件好事。大规模监视是胡说八道。是时候把面具和太阳镜搭配起来，做出决定性的一击。”由此可知，评论1对于戴口罩的规定是支持的，故选A。
