Так, це можливо. Якщо у кожної клітинки повинно бути рівно два зафарбовані сусіди, ви можете розглядати певний порядок фарбування клітинок. Наприклад, ви можете зафарбувати клітинки у вигляді горизонтальних або вертикальних смуг, де кожна клітинка має двох зафарбованих сусідів.

Read the texts about unusual jobs the three people are talking about.

S p e a k e r 1. I’ve been doing my job for so long. There are not many lighthouses anymore, everything’s so modern and advanced these days, it’s all radar and GPS. But lighthouses are still very important in certain areas and my job is to clean the lights and make sure the glass in front of the light is clean and smooth. My job is not dangerous because we do the cleaning and maintenance during the day and only when the weather is good. I’ve seen some very bad storms though. Five years ago, I was trapped on a small island in Wales for two days while we waited for a storm to pass. Even though my job is very unglamorous, I’ve met a few famous people. One old football player owns a lighthouse in Northern Ireland and he told me stories about famous games while I was working. And last year, the Queen was there when an old lighthouse that had been renovated was reopened, and we spoke about my work for a few minutes.

S p e a k e r 2. I am a flying doctor. I don’t have wings, but we have a small plane to reach patients who may be hundreds of kilometres away. Flying in the plane is always the most exciting part of my work. We fly quite low and the Australian scenery is spectacular. Australia is a very big country and away from the coasts, there is a lot of space and very few people: your neighbour might live on a cattle station fifty kilometres away. If you get sick, it’s easier for us to fly to you. Just in the last year, I’ve delivered seven babies and I’ve collected three people and taken them to the city for life-saving operations. I’ve even helped one of Australia’s most famous children’s novelists to have a liver transplant. I also can diagnose people using the telephone or a WebCam. Australia is a huge country and it isn’t getting smaller so I think there will always be a place for us.

S p e a k e r 3. I’ve had a lot of unusual jobs in my life. I’ve made candles at home in the shape of the Eiffel Tower, I’ve sold cat and dog food over the phone and I’ve even done a job where people paid me to wait in a queue! Now in my current job, I’m a mystery bad customer. My job is to go into stores or restaurants to complain and to see how the staff treats me. Companies pay me to do this because they want to know that all customers are treated well! Actually, it’s a lot of fun: more acting than working! I’ve complained about how dirty the tables were in a London pub, I’ve sent sushi back to the kitchen because it was “undercooked” and, last month, the manager of a shoe shop in Cambridge called the police because I asked to buy two left shoes! My job is never boring!
