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.
Answer: whether mood affects their learning ability
Solution is here: Researchers did experiments on kids in order to find out _ .
Explanation: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment.

Now, solve this: Article: Forget the pyramids, Tahrir Square and the Nile. Egypt is ready to ditch Cairo and build a shiny new capital if the government has its way. Fed up with pollution, traffic jams, a packed population with soaring rents, Egypt is teaming up with a developer in the United Arab Emirates to build a city in what could be one of the world's most ambitious infrastructure programs. The yet-to-be-named city will spread out over 150 square miles, or roughly the size of Denver, and could eventually be home to 7 million people, the developers and government announced Friday. The current capital of Cairo, while full of history and vibrant charm, is home to more than 18 million people, and living in and getting around the city can be maddening and frustrating. The government says the idea is to reduce congestion in Cairo, which is projected to double in population in the coming decades. An exact location was not announced, but the city is expected to be built east of Cairo. It will be closer to the Red Sea -- between two major highways -- the Suez and the Ain Sokhna roads. The ambitions are big. In addition to the new embassies and government buildings, it plans to have an international airport bigger than Heathrow, solar energy farms, 40,000 hotel rooms, nearly 2,000 schools and 18 hospitals -- all linked together by over 6,000 miles of new roads. _ The total cost is estimated at U.S. $45 billion, Minister of Housing Mostafa Madbouly announced at an economic development conference in Sharm el-Sheikh. The revealing of the new capital was paired with a glamorous website showing a luxurious and technological urban view of glass towers and pools. The plan is backed by a group that describes itself as "a private real estate investment fund by global investors focused on investment and development partnerships" led by Emirati developer Mohamed Alabbar. Alabbar made his name as the founder of Dubai's Emaar Properties, primarily known for developing the world's tallest building, the Burj Khalifa. Egypt is not the first country to plan on moving its capital from established big cities to rural greener pastures. Myanmar has only recently completed its move from Yangon to the new city of Naypyidaw. Nigeria moved to Abuja in the 1990's, and Brazil carved its capital Brasilia out of the wilderness over 50 years ago. And then there was another crazy idea of building a capital city on a square of swampland that seemed mainly to be a boondoggle for wealthy land speculators at the time. That city? _
Answer: traffic jams and crowdedness
Solution:
Egypt is ready to join hands with some experienced developers to build a new capital mainly because of the following EXCEPT _ in the old capital.
