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: I had in my hand a sheet of paper with handwritten instructions on it for some sort of editorial task.It occurred at first that I did not recognize the handwriting,and then I realized whose it must be.I finally became aware of the fact that I had been working with this colleague for at least a year,maybe two,and yet I did not recognize her handwriting at that point. It was a very important event in the computerization of life--a sign that the informal.friendly communication of people working together in an office had changed from notes in pen to instant messages and emails.There was a time when our workdays were filled with little letters,and we recognized one another's handwriting the way we knew voices or faces. As a child visiting my father's office,I was pleased to recognize,in little notes on the desks of his staff,the same handwriting I would see at home in the notes he would leave on the fridge-- except that those notes were signed"dad"instead of"RFW". All this has been on my mind because of the talk aboutThe Rise and Fall of Handwriting,a book by Florey.She shows in her book a deep concern about the fall of handwriting and the failure of schools to teach children to write well,but many others argue that people in a digital age can't be expected to learn to hold a pen. I don't buy it. I don't want to see anyone cut off from the expressive,personal associations that a pen still promotes better than a digital keyboard does.For many a biographer,part of really getting to know their subjects is learning to read their handwriting. What some people advocate is teaching one of the many attractive handwritings based on the handwriting of 16th--century Italy.That may sound impossibly grand--as if they want kids to learn to draw by copying classical paintings.However,they have worked in many school systems.
Answer: He had worked with his colleague long enough.
Answer:
Why was the author surprised at not recognizing his colleague's handwriting?
