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: I got into the teaching profession by choice. I was then in 9th grade, when my mathematics teacher asked me to take a class for a few students to whom the subject seemed difficult. And believe me, I enjoyed the teaching. I never knew teaching would be so interesting. I loved my freshmen and was delighted to teach my so-called students who came up with lots of good questions. After my post graduation, I worked as a software developer with a public sector in Bangalore for a few years. But I realized that no job could provide me the satisfaction that I experienced while teaching and training. In fact, I feel it was a timely realization for me to choose the teaching profession. I applied to a few colleges, and finally I was chosen as a "Lecturer", and I had to lecture graduate and post-graduate students in a college. On the first day, I was nervous thinking that I had to teach the senior classes. But now I can say that taking lectures was one of the best experiences of my life. I was a Computer Science and Information Technology Lecturer, but I tried to help my students with subjects that were not within my domain . It was a new feeling to me every morning before going to the classes. I used to feel energized and excited thinking that the class would be lit up with bright faces to greet me, "Good morning, Madam". To me each day was a new beginning, with new feelings, new experiences and new queries . I loved to explore their young minds, read their inquisitive faces when a particular topic seemed tough. It was very challenging to motivate them to take part in the classroom, think critically, question and also respect others' point of view. Though few things never seemed easy, it was very exciting to assure them that they really can. That is the reason, I love to teach.
Answer: Because he wanted to try more chance to challenge his value.
Example Output: Why did the author refuse working as a software developer?

Example Input: Article: Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish.
Answer: The comparison between dolphins and humans.
