During a visit to the school library, a group of 4th graders wants to interview a renowned children's book author. They are preparing a list of questions to ask about the author's inspirations and writing process. As part of their preparation, they need to understand the structure of questions in English. The students are specifically learning to form questions using various question words and sentence structures. Based on their lesson, which aims to help them recognize and apply the basic form of questions, they are asked to identify the correct way to ask about the author's favorite childhood book in an interview setting.
