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.

Let me give you an example: Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.
Answer: 10,000,000 or less.
The answer to this example can be: How many books are there in the British Library?
Here is why: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

OK. solve this:
Article: Stacey Hillman, who is 10 years old, was reading a magazine about police dogs needing bulletproof vests . She thought that someone should start raising money for the police dogs. After she got permission from Chief LaBrusciano, she went to the County Sheriff Don Eslinger. She got busy visiting all the police dogs and telling the departments about her new charity. She made "collection boxes" by using bottles and put a picture of her with a police dog on it. She put these bottles in vet's offices and pet stores. The Chief from her hometown police department helped make Stacey's idea an official charity -- Pennies to Protect Police Dogs. The more money she collected, the more popular she became, and the more people offered to donate and help her with her goal of giving every police dog effective protection. Stacey travels all around her state to raise money and tell people how important the police dogs are. She speaks at schools, and they donate to her charity, too. Since Stacey started her charity, she has bought bulletproof vests for the police dogs with all the 140 thousand dollars she has raised. But she has many more K-9 friends that still need to be protected and she promises to keep doing her charity until every police dog in the whole country has a bulletproof vest. Each vest costs $700, and every police dog should have one. There are not always tax dollars to provide K-9s with these vests, and very few departments have them. The police dogs save lives just like police officers do, and often the police dogs are the first to go in. Stacey depends on donations from everyone to provide the dogs with bulletproof vests.
Answer: An article about police dogs' problem.

What made Stacey begin to consider doing something for the police dogs?
