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.
One 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.

Now, solve this: Article: It's going to be a busy day at Betsy Ross house in Philadelphia on Thursday. She won't be there, since she died in 1836, but hundreds of tourists will be going through her house. You see, Thursday is Flag Day in the United States. The unofficial holiday commemorates the adoption of the stars-and-stripes design of the American flag by the Continental Congress 235 years ago, on June 14, 1777. According to lore, the Ross House is the birthplace of the nation's flag. That's open to debate, but it's a story that schoolbooks still tell. Betsy Ross was a _ , busy sewing cushions for chairs in Philadelphia, which was the focus place of the American revolution against British rule. The Declaration of Independence by the colonists was signed there, and so was the new nation's Constitution after independence was won. Widowed when her husband, a member of the local militia, was killed in a gunpowder explosion, Betsy Ross often mended the clothes of the rebels' leader and future U.S. president, George Washington. According to what some say in history and others a stretch of what really happened, Washington asked Ross to design and sew the new nation's flag. The story was promoted by Ross grandson, who wrote that Betsy Ross had "made with her hands the first flag." She became a role model for girls - a shining example of women's contributions to the nation's history. Most research indicates that Ross did sew the first flag. She's credited with substituting artful five-point white stars for six-pointed ones in the upper-left blue field. But many other accounts indicate George Washington brought the design to Ross and simply asked her to stitch it together. In a letter, Washington wrote: "We take the stars from Heaven, the red from our mother country, separating it by white stripes, thus showing that we have separated from her. And the white stripes shall go down to posterity as representing liberty."
