In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.

Example Input: Article: The fact that blind people can see things using parts of their bodies apart from their eyes may help us to understand our feelings about color.If they can sense color differences, then perhaps we, too, are affected by color without knowing it.Salesmen have discovered by experience over a long period of time that sugar sells badly in green wrappings, that blue foods are considered not agreeable to the taste, and that cosmetics should never be packed in brown.These discoveries have grown into a whole subject of color psychology. Some of our preferences are clearly psychological.Dark blue is the color of the night sky and therefore connected with calm, while yellow is a day color connected with energy and encouragement.Experiments have shown that colors, partly because they are connected with psychology, also have a direct effect on people's mind.People in bright red surroundings show an increase in breathing speed, heartbeat and blood pressure.Red is exciting.Pure blue has exactly the opposite effect; it is a calming color.Being exciting, red was chosen as the signal for danger, but a closer study shows that a bright yellow can produce a more basic state of alarm, so fire engines in some advanced areas are now rushing around in bright yellow colors that stop buses, trucks and cars.
Answer: found out that colors affect sales
Example Output: The passage tells us that salesmen have _ .

Example Input: Article: One of the major functions of an iPhone is, of course, to play music. The iTunes app has been designed in such a way as to take advantage of the iPhone's touch screen. But what if you want to listen to music that isn't in your iTunes library, or you want to discover new music without sitting in front of computer? There are plenty of ways to access music, but not everyone knows what options are available. Either that, or there are so many options that going through all of them is tiring. For these reasons, here we offer a few convenient ways of listening to music on your iPhone without using iTunes. Stream some radio (Tuneln Radio) Tunnel Radio provides a quick and easy way to listen thousands of Internet radio stations on your Apple products. In addition to local radio stations, this app compiles more than 40 000 radio stations from around the country. What makes the app special is that it allows you to pause and rewind live radio----pause your station to take a phone call or rewind to replay a favorite song. You can also browse by genre of location, and the app includes plenty of talks, news, sports and weather stations in addition to music. From desktop to smartphone (QQ Music) QQ Music seems like obvious choice, and it is. It's a streaming service based on the Tencent technology that is already wildly popular on the Internet and now also offers a (free) app. Through this app you can listen to existing playlists or create new ones based on the patterns of music you like. It works amazingly well and everything can be saved to your QQ account for access from a computer. What was that song? (Shazam) Shazam is an innovative and free app that cures your"what was that song?"problem. It happens to all of us : we hear a song (on TV or in a store ), love it, know we have heard it before but just can't remember what it is called . With Shazam you don't need to. Just hold your iPhone up and through its microphone, Shazam will identify the album, artist and song title for you. You can then either purchase the song in iTunes or search it on other apps for streaming. How cool is that?
Answer: iPhones
Example Output: All of the options are strongly recommended to the users of _ .

Example Input: Article: DNA left at a crime scene could be used in the future to build up a picture of an offender's face, it was revealed tonight. A first step towards genetic _ has been taken by researchers in the US who link specific DNA markers with face shape. To identify the genes, they focused on known mutations that cause changes of the face and head. Normal versions of these genes were found to influence individual features. For instance, one gene affected the lips, another the shape and configuration of bones around the eyes, and a third the appearance of the mid-face and skull. In total, 20 genes had "significant effects" on facial appearance. Lead scientist Professor Mark Shriver, from Pennsylvania State University, said: "We use DNA to match to an individual or identify an individual, but you can get so much more from DNA. Currently we can't go from DNA to a face, or from a face to DNA, but it should be possible." The implications are far reaching, raising the possibility of creating a data bank of facial types based on genetic markers. DNA from a crime scene could then be used to produce a rough image of the face of an offender or victim. Such genetic mugshots may be more reliable than computer-generated "e-fits" based on witnesses' recollections. Other uses of the technique might include proving the identity of fathers in paternity cases, or visualising our remote ancestors from fossil DNA. The scientists wrote in the online journal Public Library of Science Genetics: "Such predictive modelling could be forensically useful; for example, DNA left at crime scenes could be tested and faces predicted in order to help to narrow the pool of potential suspects. Further, our methods could be used to predict the facial features of descendants, deceased ancestors, and even extinct human species. In addition, these methods could prove to be useful diagnostic tools." The team developed a model which first established a range of physical face shapes from people of mixed West African and European ancestry from the US, Brazil and Cape Verde. Measurements were taken of thousands of point co-ordinates on grids placed over 3D images of the faces. Statistical methods were then used to determine the relationship between facial differences and the effects of gender, ethnic ancestry and individual gene variants.
Answer: there is a possibility of going from DNA to a face
