A、It has unexpected results in the real world. B、It is great and helpful in the real world. C、It has gone through the controvers

In the rush to reinvent the way we live, do the tech reformers forget the negative impact some of their miraculous products can have on the lives and jobs of many people?
    Take facial recognition as an example. Have you ever come across someone whose face you recognized but you couldn’t remember his or her name? It’s always happening to me.
    The augmented reality company Blippar already allows you to scan objects with your smartphone’s camera to find out more about them—now you will be able to scan faces too.
    But facial recognition software can be controversial, and this could be another innovation which sounds great in a brainstorming session but has unintended consequences in the real world. We hear from Blippar’s co-founder Omar Tayeb who tells us how the app works, and why we shouldn’t be worried about its implications for privacy.
    Another story is about another area where the tech industry’s reputation is coming into question—the fake news spread over social networks and via Google searches.
    The tech firms are now starting to help readers understand what is true and what is not, but what can the traditional media firms do?
    Critics of the mainstream media will argue that the problem started long before many people got their news online. So whose job is it now to decide what is true, and put clear markings on fake news? You might think that was the function of editors, but Alex Sander of The Guardian tells us “It’s the readers’ job to mark things as fake. "
    Questions 9 to 11 are based on the passage you have just heard.
