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.
One 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.
Solution is here: How many books are there in the British Library?
Explanation: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

Now, solve this: Article: I turned 16 on Friday, but the Driver's License Office in my small hometown was only open on Tuesday, so I had to wait through that extremely long weekend and an endless Monday before going in for my examination. I came to the Driver's License Office half an hour earlier _ , pacing back and forth on the worn porch waiting for the office to open at eight. I reviewed the driver's manual for the hundredth time. I was ready. I knew the manual backward and forward; I had made an "A" in my driver's training course, and I was a genius behind the wheel. Finally, the door opened and a weary-looking man in a brown uniform let me in. "Let me guess. You want to take the driver's test." his voice was not enthusiastic. "Yes!" I answered in excitement. "Ok, fill this out, and if you pass we'll go for a drive." _ . A quick check showed that my paper was perfect. "Let's get in the car." He tossed me a set of keys, and I slid behind the wheel. Everything was going smoothly as we pulled out of the empty parking lot. I signaled a right hand turn, and we were on a deserted street. This was going to be easy. "Turn left and go up Young Blood Hill," he ordered. My hometown is in the mountains, and Young Blood Hill was almost vertical . As I eased up the steep hill and came to a stop at the top, I heard the car's engine die. My heart sank. I would have to start it again without rolling back down the hill. I swallowed hard and turned the key; as I moved my foot from the brake, the car began to roll. I suppose I could have rolled all the way back to the bottom except for one thing. There was something behind me which stopped my roll with a rough shake and crash of glass--a police car. The policeman wrote me a ticket as I looked over the damage, and the man from the Driver's License Office slid behind the wheel. I waited until we had parked before I asked how long a person had to wait before taking the test again.
Answer: It hit a police car.
Solution:
Why didn't the car roll back to the bottom?
