Schools, motorways and an airport were closed on Tuesday as visibility in some areas of the city dropped to less than 10 meters. Photos from Harbin showed residents covering their mouths with masks and scarves, and moving like ghostly shadows through the fog. Cars and motorcycles are moving slowly as traffic came to a standstill with traffic lights barely visible. . Just days previously , the World Health Organization's International Agency for Research on Cancer (IARC) classified air pollution as a carcinogen . It stated that there is " sufficient evidence" that exposure to outdoor air pollution causes lung cancer and also linked it with an increased risk of bladder cancer. It's said that exposure has increased significantly particularly in " rapidly industrial countries with large populations". "The air we breathe has become polluted with a mixture of cancer-causing substances" , Dr Kurt Straif , head of the IARC said in a press released. "We now know that outdoor air pollution is not only a major risk to health in general, but also a leading environmental cause of cancer deaths. " On the Chinese social media site Weibo , many users complained about the pollution and shared their concerns. References to "feed people with smog "have become popular on Weibo and there is a sarcastic play on the expression "serve the people" , as the two have a similar pronunciation.

input: Please answer the following: Write a multi-choice question for the following article: Article: Today anyone will accept money in exchange for goods and services. People use money to buy food, furniture, books, bicycles and hundreds of other things we need or want. When they work, they usually get paid in money. Lots of the money today is made of paper. But people used to use all kinds of things as money. One of the first kinds of money was shells. Shells were not the only things used as money. In China, cloth and knives were used. In the Philippine Islands, rice was used as money for a long time. Some Africans once used elephant tusks, monkey tails, and salt as money. The first metal coins were made in China. They were round and had a square hole in the center. Different countries have used different metals and designs for their money. Later, countries began to make coins of gold and silver. But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper money looked more like a note from one person to another than the paper money used today. Money has had an interesting history, from the days of shell money until today.

input: Please answer the following: Write a multi-choice question for the following article: Article: I stole your dog today. No, I didn't set a foot on your house, but from the condition of your dog, I can imagine what it looks like...the word "rubbish" comes to mind. I found her along a road, with a heavy chain wrapped around her neck, still attached to rotten boards from her doghouse. Not only did I know that most of the town people had already ignored her, judging by where I found her, but I knew that if she had gotten into the Woods, the "cross" that she dragged behind her would have wrapped around a tree until starvation or thirst killed her. She has a beautiful name now. Already in the first week she has come to look more like she should. Her eyes sparkle and she has learned to wag her tail in greeting. She has stopped flinching when I make a sudden movement, because she knows now that I won't beat her, in fact, she rarely leaves my side. She's even become brave enough to bark at a cat and today I watched from the window as she attempted to play with the other dogs. No, it's clear she does not miss you or her former life on a chain. It's not clear yet whether she'll remain here or whether I'll find her a loving home where she can count on more individual attention than I can give her, but one thing is certain, this is one bit of stolen "property" who is never returning to you. So sue me, accuse me, plead with the courts that she is rightfully yours ... I'm convinced this is the best "crime" I've ever committed. Hardly anything has pleased me more than the day I stole your dog. I need only look into her beautiful brown eyes to know that she'd defend my decision with her life. If we have one prayer, it is that you will not replace her, and if we have one special day to celebrate together, it is the day I stole your dog and the day she stole my heart.
