Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: How many books are there in the British Library?
Reason: 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 instance: Article: Most people are aware of what the adoption process is because it has become rather common in our society. Adoption is where a child is legally placed with guardians or parents (or perhaps a single parent) other than the birth mother or father. Once an adoption is finalized, all parental rights are turned over to the adoptive parents and there is no legal difference between adoptive parents and natural birth parents. There are generally two types of adoption, which are closed adoption and open adoption. When an adopted person has access to his or her adoption file and original records, it is referred to as an open adoption. The term is also used to describe any contact that may be between the adoptive family, the birth parents, and the adopted child. The level of openness can change greatly in such contact depending on each individual relationship. There can be indirect contact between the natural birth parents and the child through the form of letters and photographs, or there can be actual physical contact. A semi-open adoption is where the birth parents may have contact with the adoptive parents before the birth of the child, either once or several times. After the birth there is no more contact. A semi-open adoption may remain as it is or it can become either open or closed. A closed adoption is where only the medical and historical information about the biological parents is given to the adoptive family. Typically, the birth and adoptive parents do not know each other's identities. The record of the birth parents is kept sealed . A closed adoption is usually only effective in the adoption of babies. The adoption of an older child who already knows his or her birth parents cannot be kept closed.
