In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.

Example Input: Article: Cloud seeding is a method of artificially causing clouds to produce precipitation in the form of rain or snow.Cloud seeding has also been used in attempts to modify the severity of hail storms and hurricanes.The effectiveness of cloud seeding remains controversial .but it continues to be used in some regions to try to increase rainfall for agriculture and to build snow packs for water supplies and power production. Cloud seeding was developed by American scientists Irving Langmuir and Vincent Joseph Schaefer during and after World War II.Their work began as an effort to learn more about the buildup of ice on airplane wings, and eventually led them to attempt to create rainfall by releasing several pounds of crushed frozen carbon dioxide into a cloud from an airplane.In this form, the carbon dioxide is called dry ice.On November 13, 1946, the technique appeared to produce snow directly under the cloud; the snow then turned to rain as it fell to the ground. For their experiment, Langmuir and Schaefer selected a supercooled cloud, one in which the water droplets remain liquid in subfreezing temperatures.Their theory was that small grains of dry ice falling through the cloud would cause tiny droplets of water vapor in the cloud to freeze into crystals that attracted more water vapor.Their theory proved to be correct and eventually the crystals became heavy enough to fall from the cloud as snow.As the snow reached the warmer temperatures closer to the ground, it melted and became rain. Another scientist, Bernard Vonnegut, produced a method of cloud seeding using silver iodide .He used particles of silver iodide because its crystal structure resembled that of ice in clouds.Silver iodide also had practical advantages over frozen carbon dioxide It could be stored at room temperature and did not require an airplane as a delivery mechanism.Instead, silver iodide crystals could be fired by cannons high into the air, where wind carried them into the clouds.
Answer: it is similar
Example Output: Bernard chose silver iodide as a method of cloud seeding because _ .

Example Input: Article: While in college, Tim started to look for easy ways to make money. One of the opportunities he saw was gambling . He started learning about all forms of gambling. He got lucky enough to make $9,000, but sadly it didn't last long and over the next year he lost all of that money. It was at this point that Tim realized that he needed to stop gambling and focus on learning about finance. One day, he was talking to one of his friends about creating a business, and his friend turned him onto Quick Sprout. So he started reading every blog post on Quick Sprout in the hope that he could learn about how to become a successful businessman and meet some people through Quick Sprout that he could partner up with. A year ago Tim read a blog post on Quick Sprout about another businessman by the name of Timothy Sykes. Tim visited Timothysykes.com and learned about his Millionaire Challenge program that taught people how to buy and sell penny stocks . Tim thought it would be worth giving a try. Tim spent the next few months learning from Timothy Sykes on how to trade stocks. After he felt that he had learned enough, he wanted to start trading. Within the first 6 months of using what he learned in the Millionaire Challenge program, he made over $40,000. At one point he even made $11,000 in 15 minutes. Over the next 12 months Tim is on track to make even more money. So far things are looking good and he is already ahead of schedule. The Millionaire Challenge program has worked out so well for him and he is now starting to enjoy the finer things of life.
Answer: he lost all the money he got from gambling
Example Output: Tim decided to learn about finance when _ .

Example Input: Article: Tile Spring Festival is almost over,but the celebrations are continuing.The Chinese embassy in Sydney have devoted a day to celebrating the Spring Festival and Chinese culture. Tile carnival features a series of cultural performances and demonstrations,bringing the Spring Festival fun to Sydney.Over the past four years,the annual event has become popular not only with tile Chinese community but also with locals.And some have even set up their own stalls to allow more people to learn about China and the country's culture. This is my second time to have a stand here,but I've been here many times before."said Carole Kyle from Sydney.Carole has brought along some brochures about Project Hope which supports Chinese students who drop out of school due to poverty. China's Ambassador to Australia Ma Zhao xu hopes that this kind of event will facilitate a dialogue between people from the two countries. "In Chinese culture,we appreciate unity without uniformity,and harmony in diversity. Australian culture welcomes cultural diversity,so that is a good foundation for Sino-Australian relations,to further our understandings and strengthen our friendship."Ma said. Sydney's mayor Clover Moore was also present and echoed Ma's view. "In fact we have Chinese living in Australia since the middle of the 19th century,so it goes way back and there has been a strong link between China and Australia for many many years.We have a very ancient culture here,the aboriginal culture.You have a very ancient culture in China.We'd like to marry those two and celebrate them."Moore said. A centre about Chinese culture in Sydney is also set to have a test run in March,and will be the biggest of its kind in the Oceania region.
Answer: the Chinese culture is popular with the local people
Example Output:
