问题    If a potential customer enjoys your advert, they are more likely to buy your product. It’s a simple【C1】______ , but it is extremely difficult to know how well your advert is being received in the real world. Now a new system could help【C2】______ know exactly how their latest offering is going down with viewers, just by watching their face.
   The system, developed by Daniel McDuff and colleagues at the Massachusetts Institute of Technology Media Lab, looks at how【C3】______ in the face move in response to watching a video. Software can then classify what counts as positive【C4】______ responses and smiles during the video and from that predict which adverts the viewer most enjoys. The team collected more than 3 200 videos of people, whose faces were【C5】______ by their own computer’s webcam as they watched three adverts online during the Super Bowl in 2011. After each commercial—one for Doritos, one for Google and one for Volkswagen—the viewers were asked if they liked the video and whether they would want to watch it again. In tests, the system made correct【C6】______ more than 75 per cent of the time.
   The system would be a【C7】______ for advertisers trying to grab the attention of potential customers on the Internet. In future, the system could be used to personalize adverts for viewers as they watch programs online, depending on their【C8】______ , or as a more【C9】______ way of testing how good a new advert is at【C10】______ to customers.
A) facial F ) created K) predictions
B) boon G ) suggestions L ) advertisers
C) reaction H ) concept M) appealing
D) filmed I ) effective N) people
E) face J ) eyes O) muscles
