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: When I worked as a waitress in Chicago, US, my coworkers and I would sigh whenever we heard someone with a foreign accent coming into our restaurant. We knew what it meant to serve a non-American: no tip. We would work just as hard as we always did, but we might not get paid. Americans have an unspoken rule about tipping: they give tips to almost everyone who offers them a service of some kind. Americans tip their waiters, barbers and taxi drivers. An appropriate tip is between 15 and 20 percent of the amount charged for the service (But the charge for the tip doesn't appear on the bill. The customer is expected to add it himself/herself.) Tipping less than this sends a message to your waiters that you think they've done a bad job serving you. And to leave no tip at all is simply unacceptable. It's not that American waiters are greedy. In many countries, waiters are paid a salary for their work. They'll earn money even if no one comes into the restaurant. This system offers much more safety for waiters than the American version. In the US, waiters know that a night without customers means a night without pay. Some countries include a tip for waiters - a "service charge" - on the bill itself. Since the tip is included with the other charges, waiters don't need to worry about people forgetting to tip. But in the US, waiters do not receive a salary, and service charges only appear on bills when there are six or more customers at the table. Since almost all American customers are familiar with the system, they know to add a tip without being told. But visitors to the US may expect waiters to be paid a salary, or think that the tip is included on the bill. So much as we waiters loved hearing stories about other places from our foreign customers, we were always nervous when they got ready to leave the restaurant. We were never sure what to expect.

Example Input: Article: It seems that beauty and women are twins.You are joking? No,I do not.Observe for yourself Ads on fashion TV screens,radio programs,magazines,newspapers,and the streets.Whether they have realized it or not, women are surrounded by a sea of fashion.They are taught to think that without beautiful clothes they will grow old and lose their charm.So who dares to neglect dressing up at the cost of their appearance and youth? But I do not agree with the opinion that women have to show their beauty through their looks.The richness of their minds proves to be more beautiful and attractive than their looks.A woman who has experienced many troubles and may be called "aunt" or "granny" can still keep up her beauty if she has such excellent qualities as knowledge,ability,a kind heart,great courage,concern for others,etc. In addition,old and young,beautiful and ugly are concept.People who keep a young mind will never feel old.Interested in new things and eager to learn more,they keep up with the tide.Plainly dressed women may have a type of beauty that is pure and real.Reading and learning is the best way to keep one youthful.Good books ale rich soil which can feed the flower of one's heart and looks.
Answer: Richness of one's mind.

Example Input: Article: I had to knock on the taxi to get his attention. Finally, the driver, a man about 60, looked up from behind the wheel and apologized, "I'm sorry, but I was reading a letter." He sounded as if he had a cold or a cough. Since I was in no hurry, I told him to finish his letter. He shook his head, explaining that he had already read it several times and almost knew it by heart. Curious, I asked whether it was from a child or maybe a grandchild. "This isn't family," he replied. "Though he might just as well have been a regular member of the family, Old Ed and I grew up together." They were always friends. But since he moved away from the neighborhood 30 years ago, it'd generally just been postcards at Christmas time between them. A couple of weeks ago, Ed died. "I should have kept in touch." He repeated this, more to himself than to me. To comfort him, I said sometimes we just didn't seem to find the time. "But we used to find the time," he said. "Take a look." He handed the letter over to me. The first sentence "I've been meaning to write for some time, but I've always delayed it." reminded me of myself. It went on to say that he often thought about the good times they had had together. When I read the part where it said "Your friendship really means a lot to me, more than I can say because I'm not good at saying things like that", I found myself nodding in agreement. We had gone several kilometers and were almost at my hotel, so I read the last paragraph: "So I thought you'd like to know that I was thinking of you." And it was ended with "Your Old Friend, Tom." "I thought your friend's name was Ed," I said. "I'm Tom," he explained. "It's a letter I wrote to Ed before I knew he'd died. I never put it in the mailbox. I guess I should have written it sooner." His face was pale as he wiped his eyes with a handkerchief. When I got to my hotel room I didn't unpack right away. I had to write a letter and post it.
Answer: Tom
Example Output:
Who wrote the letter?
