Okay kiddo, so there's this famous scientist named Albert Einstein who was really good at math and science. One day, he made up a special problem to test people's creativity and problem-solving skills. This problem is called the "Einstein problem."
The problem goes like this: In a street, there are five houses painted in five different colors. In each of the houses, there lives a person of a different nationality. The five persons are a Norwegian, a Dane, a Brit, a German, and a Swede. These persons drink tea and coffee, each of a different brand, smoke a different brand of cigar, and keep a different pet. The question is, who keeps the fish?
Now, this might seem like a silly question, but it's actually a really tricky puzzle. You have to use all the clues given to figure out who keeps the fish. For example, you might know that the Norwegian lives in the first house and drinks coffee, but you still have to figure out who keeps the fish.
To solve this problem, you need to use your brain really hard and think outside the box. You have to be patient and pay attention to all the details given. It might take some time, but once you figure out the answer, you'll feel really smart!
So, that's the Einstein problem. It's a fun challenge that can test your problem-solving skills and creativity.
