Given the task definition, example input & output, solve the new input case.
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: 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.

Output: Researchers did experiments on kids in order to find out _ .
It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment.

New input case for you: Article: Do you think Great Britain and the United States are alike? Winston Churchill once joked that the people of Britain and the people of America are separated only by their language. Do you think that is true? The British and the Americans both speak English as the official language. However, each uses some different words.We Americans are similar to the British. After all , our country was once owned by Great Britain , so we have a lot in common. But there are many differences between us. Great Britain has a king or queen, and the leader of the government is the Prime Minister. The United States has no kings or queens. Our leader is the President. Both the British and Americans use pounds and ounces, oints, quarts, and gallons. Both use miles, yards,and feet. Our money is different,though. The British use pounds and pence. Americans use dollars and cents. Driving in a car is very different in England. They drive on the left side of the road. We drive on the right. What we call the hood of the car, the British call the "bonnet". British cars run on "petrol",which we call gasoline. In our everyday lives, we do many of the same things as the British. But we describe them differently. A young mother here might push a baby in a baby carriage. A British mom pushes a "pram". The British watch the "telly", while we watch TV. We like to eat French fries, but the British call them "chips". Millions of Americans drink coffee, but most British prefer tea. So we are different in many ways. But we stay friendly anyway.
