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: There are hundreds of national parks and wildlife areas in Africa that you can travel to. Here are the top four travel destinations in Africa: Tanzania----Serengeti National Park During the annual migration , when the wildebeests  and zebras pack up and leave their living areas to find fresher ones, the Serengeti is an astonishing place to be. It's a very good travel spot in Africa at other times of the year too, but the migration has been ranked by many as one of the wonders of the natural world. Kenya----Masai Mara National Park If you want to see the big cats, this wildlife park is the best of the best. Lion, leopard and cheetah abound and they are relatively easy to spot because of the grassland vegetation which means you get good views for miles around. Another big plus is the fact that going off road is allowed and it is a big advantage because the animals will rarely oblige you and stay next to the major roads. South Africa-Kruger National Park For the variety of species no other places in Africa can come close to the Kruger Park. And because it is so large it has a number of different ecosystems that you can pass through in your search for animals and birds. It is one of the best managed parks in Africa and the accommodation is well-equipped, too. Zambia-South Luangwa National Park South Luangwa is a diamond in the rough, just waiting for enough exposure to bring it to its rightful place in the crown of prime Africa trips. It has been regarded as one of the best places in Africa to see the special leopard and it is the birthplace of the walking travel.
