Please answer this: Write a multi-choice question for the following article: Article: Is the world too crowded? Well, that's a hard question to answer. It's all a matter of perspective .In Montana, you might drive for a mile in any direction and not see another human being. In Macao, 60,000 people live in every square mile! What is true is that the world's population doesn't stay the same. It has been increasing at a very fast rate .That's in part because in each generation these are more people who then have children than in the last generation. Five hundred years ago, the population of the world was about 460 million. In 1900,the world's population was under 2 billion .Right now it is doubling every 40 years. That means, if this rate of growth continues, when you are a parent, there will be twice as many people on earth as there are now. Wow! Now that's a whole lot of people! Soon the world's population will probably reach 7 billion. Some people worry about that! But there is a lot of disagreement about just how many people on earth equals too many people. But everyone agrees that the more people there are, the more resources the world needs to feed, house and take care of all of them, and the more need there is to think carefully about how we live and use the earth's resources.

Please answer this: Write a multi-choice question for the following article: Article: Hundreds of people did not get their train tickets through the online train ticketing service after paying the money. The China Railway Customer Service Center said that it would try to solve the problem and return the money in 15 working days. The service center said changes would be made to the online booking system which limited each purchase which is finished in 30 minutes. Many people said that they failed to book tickets because of the time limit in purchase. People who paid without getting their tickets have formed groups on QQ. As many as 400 people had joined the QQ group by Thursday and the group continues to grow. The ticket buyers said their money had been returned through online banks but they didn't get confirmation from the online booking system. They are afraid that they will not be able to get refunds because they don't have the order number given to those who have succeeded in booking. People also said they were unable to inquire through the booking hotline 12306, because it is almost always busy. The China Railway Customer Service Center Website suggested that the online banks didn't return the payment information to the online booking system because of network problems. The online railway booking service was made by the Ministry of Railways on Dec. 21, in order that people can easily buy train tickets during the Spring Festival.
