[单选题]科学的实质虽没有充分发扬，科学的名义却已不胫而走，到处可以看到了。科学成了一个招牌，给市侩的商品宣传；甚至科学成了一个烟幕，给迷信欺骗作掩护。月饼的广告中用着“科学焙制”这样的字样，或者还不值得计较，但“科学圆光”、“科学扶乩”、“科学相面”这样的说法也一直是大吹大擂，那实在是不能不令人愤怒的。偶然看到一块“科学相面”的招牌，人们大概总是一笑置之的吧。但仔细一想，这实在不是可以一笑置之的事。在这情形下，其实是这块招牌，在嘲笑着你，它代表了整个的腐败落后的旧社会，在向你说：你们不是提倡科学么？你们不是反对迷信么？但是我倒偏偏不反对科学，而且我也可以就是科学。--于是胜利者并不是你而是它。招牌依然高高挂着。骗人的勾当依然在继续进行着。科学没有打倒它，好像倒只是为了供给它一个更有利的骗人的名义。最适合这段文字的标题是：( )
A.《科学不是招牌》

[单项选择]Austerity is a word much found on the lips of politicians and economists at the moment; but it is seldom heard from technologists. And although the idea that "less is more" has many adherents in architecture, design and fashion, the technology industry has historically held the opposite view. Products should have as many features as possible; and next year’s version should have even more. As prices fall, what starts off as a fancy new feature quickly becomes commonplace prompting companies to add new features in an effort to outdo their rivals. Never mind if nobody uses most of these new features. In an arms race, more is always more.
But now there are signs that technologists are waking up to the benefits of minimalism, thanks to two things: feature fatigue among consumers who simply want things to work, and strong demand from less affluent consumers in the developing world. It is telling that the market value of Apple, the company most closely associated with simple, elegant hig

[不定项选择题]资料：Directions : There is 1 passage in this part. The passage is followed by some questions or unfinished statements. For each of them there are four choices , You should decide on the best choice.
Your face is the future of smartphone security. Apple made that clear last week when it unveiled the pricey iPhone X. Apple claims to have conquered many of the challenges that have prevented the widespread use offacial biometrics. But a number of computer-vision researchers say they are skeptical that a smartphone-based system like FaceID can account for things like variable lighting conditions or subtle changes in a person's appearance to create a secure-yet-practical way to unlock a phone a dozen or more times a day.
Apple’s new technology does sound promising. The company says FaceID creates a “precise depth map” of one’s visage by projecting more than 30,000 infrared dots against a person’s face, then using the phone’s infrared TrueDepth camera and high-power microchip to collect and analyze the results. Users are also asked to turn their head as they scan so the phone's machine-learning algorithm can measure the face from several angles and create a more detailed 3-D map of their features. Once the map is created and stored, the iPhone X uses infrared light to help FaceID scan a person’s face even in the dark. Meanwhile, machine-learning algorithms running on the phonekeep track of changes in a person's appearance—including glasses, facial hair and hats—so the smartphone’s accuracy improves over time.
Despite advances in facial recognition in recent years, it remains unclear whether FaceID will work in a variety of conditions while also keeping the iPhone X secure. Hackers, for example, quickly found a way to bypass the Samsung Galaxy S8's facial-recognition scanner when it was introduced in March: They tricked the device by simply showing it a photo of the user. FaceID’s use of 3-D facial maps could address that problem. But historically it has been a big challenge for such a system to recognize faces under different lighting conditions and from a variety of angles.
Apple showed off FaceID last week under relatively controlled conditions, says Arun Ross, a professor of computer science and engineering at Michigan State University. "Clearly the demo was very interesting," he says. "But at the same time some extraordinary claims were made." Apple' s Schiller said, for example, that the chance a random person' s face could unlock someone else' s iPhone X was one in a million——much more secure than TouchI
D. Ross says, however, that it is not clear how often FaceID fails to recognize its owner. When contacted, Apple declined to elaborate on Schiller' s comments.
“Like all biometrics, FaceID will have a problem with revocation,” says Vitaly Shmatikov, a computer science professor at Cornell Tech. “If a password is compromised, it can be changed—but a face cannot be changed.” Apple touts its ability to secure data on its iPhones, which do not share biometric information with the company’s servers. Still, Ross says, hackers always seem to find a way around even the tightest security.
What does Arun Ross mean by “relatively controlled condition”?
A.To start an explanation of FaceID' s using condition.
B.To mention that Apple Inc. shows their new product under a well designed environment.
C.To imply that FaceID has its limits.
D.To add a context explanation of the interesting demo.
