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.

Example Input: Article: One day, around Christmas time, fishermen off the west coast of Peru started on their traditional fishing trip. Much to their surprise, there were no fish! They knew immediately what had happened. Tales from years gone by had told them this was the result of El Nino which sometimes stop fishing for many months! El Nino is a warm _ that comes and goes along the west coast of South America. It got its name from fishermen in Peru more than a century ago. Every few years, they noticed a sudden warming in the normally cool Pacific water where they fished. Because this warming often came about around Christmas, they called it El Nino, which is Spanish for the "Christ Child". Generally, El Nino occurs every three to seven years and lasts only a few weeks to a month or more. El Nino warms the water it flows through. Because the fish and sea birds need cold water to live, many of them die when El Nino comes through. El Nino also causes both floods and droughts. It is believed that El Nino may have caused the 1993 Mississippi and 1995 California floods. And at the same time, it may have caused droughts in South America, Africa and Australia. El Nino has occurred thirteen times within the last fifty years, bringing natural disasters to many countries such as Indonesia and Peru. However, El Nino does not often trouble China. During this period China was badly hit by El Nino only once. In 1998, North China had a terrible drought, while South China was troubled by floods.
Answer: It lasts a few weeks or more.
Example Output: According to the passage, which of the following is TRUE about El Nino?

Example Input: Article: Alzheimer's disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer's patients for a century. Yet the cause and the cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it. Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children. There are also some physical tests that might show who is at risk of developing Alzheimer's disease. The tests look for proteins in brain and spinal cord fluid. The proteins appear to be found only in people with the disease. The protein tests correctly identify the presence of the disease in about ninety percent of patients. Now, a much simpler physical test to predict Alzheimer's risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signs of Alzheimer's. Using this information, they developed a test in which people were asked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke. The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of the smells in the first test had trouble with their memory and thinking in the next five years. Another study has shown a possible way to reduce a person's chances of developing Alzheimer's disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer's disease. Those who read a newspaper, or play chess or word games are about three times less likely to develop the condition. Researchers say they still do not know what causes Alzheimer's disease. But they say these findings might help prevent the disease in the future.
Answer: The patients of Alzheimer's disease.

Example Input: Article: Going green seems to be fad for a lot of people these days. Whether that is good or bad, we can't really say, but for the tow of us, going green is not a fad but a lifestyle. On April22, 2011, we decided to go green every single day for an entire year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task. With the idea of going green every single day for a year, Our Green Year started. My life and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps. Over the course of Our Green Year, we completely changed our lifestyle. We now shop at organic stores. We consume less meat, choosing green food. We have greatly reduced our buying we don't need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished. Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.
Answer: Going Green.
