Input: Consider Input: Article: BEIJING -- The rescue operations at a coal mine accident have ended with 105 miners dead. The State Council has organized an investigation team to probe into what caused the disaster in the city of Linfen, North China's Shanxi Province. Preliminary investigations show the illegal mining of an unauthorized seam , and the number of miners who had been sent down the shaft far exceeded its capacity. This mine was found to have long ignored the rules to steal state coal, and did not have a list of miners employed to check the number of miners missing after the accident. How did such a coal mine get all the necessary licenses for production? How did it pass the three safety inspections the local government organized last month? In response to this disaster, the Shanxi governor promised to set up hotlines for people to report illegal coal mines and rewards as high as 100,000 yuan for _ We appreciate the action this governor has taken to solving the coal mining problems, and we believe that the reporting scheme will help to stop the existence of illegal coal mines. But at the same time we have reason to question how governments at various levels supervise these mines. The sad fact that such a mine with serious safety problems could pass three consecutive local government safety inspections in a month is enough to tell us how ineffective the safety inspections were. What if these inspections were just a formality ? What if the inspectors were bribed by the mine owners to turn a blind eye to the safety dangers? We can well imagine what would happen if reports about mine problems were handled by such officials. So a thorough probe must find out who are responsible for the death of so many miners. A real safety inspection and management system must be established to guarantee that safety dangers will be removed.
Answer: The workers didn't operate properly.

Output: What is NOT one of the causes of this coal mine accident?

Input: Consider Input: Article: It is said that most people have not more than 30 friends at any given time, and 400 over the whole of their lives. However, on social networking sites, most users have about 150 friends. If these numbers are correct, then friendship means different things in different situations. Also, there are no rules about friendship. There are no instructions about how to make friends, how to keep friendships going, and how to finish friendships if we want to move on. People have very different opinions about this: some people would die for their friends and they value them more than family. Others say that friends are temporary, only there to help each other until they are no longer needed. If people with such different views become friends, this can lead to problems. Because of these different definitions of friendship, it is easy to be unhappy about our friendships. We may want them to be deeper or closer, or we may want to have more friends in our lives. Sometimes we simply do not have the time to develop our friendships, or we fear we have left it too late in life to start. If we move to another country or city, we have to find ways to make new friends again. This dissatisfaction shows us how important friendships are for most of us. We should not think that it could be too late to build friendships. We also need to understand that the need to be around other people is one that is shared by many. Therefore, we should not be too frightened about starting to talk to people who in the future may become our friends: it is likely that they too would like to get closer to us. Remember what people say: strangers are friends we have not met yet.
Answer: 30 friends or fewer at a certain stage.
Output: According to the text, how many friends do the majority of people probably have?
