This structure is used to form questions by adding か to the end of a polite statement. The sentence structure itself does not change; intonation alone is not used to signal a question in polite Japanese. Questions formed with this pattern can be yes/no questions or can include question words such as 何, 何時, 何歳, or 何年生. The topic is often omitted if it is clear from context, which is common in Japanese conversation.
