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.

Let me give you an example: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Article: Now that military dogs are taking on a larger role in fight, they' re also taking on more of the risks that come with going to war, including developing post-traumatic stress disorder.The New York Times reports that more than 5 percent of the approximately 650 deployed military dogs are developing some form of canine PTSD . "It really is difficult, because cace the dog experiences these traumatic explosions, it's the same as the troops," Army Lt.Col. Richard A Vargus, chief of the law enforcement branch at CENTCOM told the Military Times in September."Some dogs move right through it and it doesn't affect them.Some dogs, it takes some retraining, and some dogs just refuse to work." Like humans, military dogs exhibit a range of changes in temperaments when they develop PTSD.Some become aggressive, others retreat.But because dogs can't express what the problem is, soldiers can be put at risk if their partner simply stops doing his job without warning. "If the dog is trained to find improvised explosives and it looks like it's working, but isn't, it' s not just the dog that' s at risk," Dr.Walter F.Burghardt Jr., chief of behavioral medicine at the Daniel E.Holland Military Working Dog Hospital at Lackland Air Force Base, told the Times."This is a human health issue as well." And searching for such devices has become a key responsibility for military dogs.Even after spending six years and nearly $ 19 billion on experimenting with innovative ways to detect bombs, the Pentagon admitted in 2010 that its most sophisticated technology was no match for a dog' s nose. "Electronic equipment is great in the laboratory, but out on the battlefield, you can't beat the dogs," Bill Childress, manager of the Marine Corps working dog program told the Los Angeles Times. Just as physicians have yet to find a safe way to treat PTSD among humans, so too are veterinarians weighing a wide range of options when it comes to helping their canine patients But offering dogs the same innovative treatments that their human counterparts get, doesn't guarantee a full recovery.It's a fact that fears once learned are never unlearned.
