In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Input: Consider Input: Article: Recent research has claimed that an excess of positive ions in the air can have an ill effect on people's physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charged. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm, earthquakes when winds are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing, or from TV sets, duplicators or computer display screens. When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue , excessive anger, and some particularly sensitive people feel sick or even suffer mental disturbance. Animals are also affected, particularly before earthquakes, snakes have been observed to come out, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California. Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with streams or waterfalls. To increase the supply of negative ions indoors, some scientists recommend the use of ionisers. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.
Answer: It's a charged particle.

Output: What is an ion according to the passage?

Input: Consider Input: Article: Square dancing is a form of entertainment and physical exercise, which is a good thing. However, a group of senior Chinese ladies dancing in New York's Sunset Park were recently faced with noise complaints from nearby residents. The local court even served a summons related to a certain Ms. Wang. The news soon caused heated discussion across China, with many believing the incident to involve a cultural conflict between the East and West,while others view it as a form of discrimination against Chinese in the United States. The United States is a diverse society, and in many cases, Chinese dancers are tolerated and even appreciated. Meanwhile, the United States is a society based on the rule of law, and due to cultural differences, local regulations seem to be very different from those in China. As a result, some old Chinese ladies dancing in New York's Sunset Park found themselves caught in an embarrassing situation. Locals and immigrants from other nations view such noise as a violation of their right to enjoy _ . Calling the police is regarded as the most efficient way to solve such a problem. Before, these ladies probably did not understand local customs and rules. However, since the incident took place, they should perhaps know a little better next time and keep the noise to a minimum. People from different nations are often supposed to reach compromises, respecting and tolerating each other. Whatever your choice of entertainment, it is important not to affect other people's lives. Square dancing is only one of many activities during which people should mind their behavior. As for U.S. police practice, there might still be some room for improvement. Some were said to be rather rude, leading to the so-called "racial discrimination," which is a sensitive topic in U.S. society. If the involved parties could be more tolerant, and solve such problems without involving the court, perhaps immigrants would mix more.
Answer: Keep the noise lower.

Output: What will the senior Chinese ladies most probably do after the incident?

Input: Consider Input: Article: One morning there was a massage on the answering machine from an angry customer, complaining about her lack of service----service that had been stopped because her check had bounced. As it is my job to handle payments received, it was my duty to collect the check. As is often the case when a check bounces, I soon found that this woman's phone number was no longer in service. A check of the caller L.D told us the call had come from the manager's office of the apartment building where our customer lived. We left a message with the manager and within the hour our call was returned. I told our customer gently, sympathetically that a check she had written had been returned for lack of funds. I told her I always want to let people know about returned checks quickly because the huge fees the bank charge can cause more checks to be returned and more fees to be charged. I told her I hope she could contact the bank and get things straightened out before her problem got worse. I also told her, gently once more, that I hated to add to her problem but she would owe us a fee because the bank charges us a fee when a check is returned. She told me she had difficulties because of being on a fixed income and being in poor health. She told me she had no children but had raised several that belonged to her husband and after living with him thirty years he had left her for another woman. Finally, after she had promised to pay, I told her not only do I care about her situation, but she taught me something. When a person is angry, there may be reasons you don't know about. If you don't react with anger, you may learn what the real problem is and may in some way be able to help, if only with a little sympathy.
Answer: To charge for the fees
Output: Why did the author try to call the woman?
