It seems like there might be a misunderstanding regarding the interactive format of a drag-and-drop question, as I am unable to perform those actions directly. However, I can guide you on how to fill in the blanks:
To answer the question, "Nebulae are where _____ can form," you would typically fill in the response containers as follows:
- Enter response container 1: "where"
- Enter response container 2: "stars"
Thus, the complete statement would read: "Nebulae are where stars can form."
If you specify the exact options you have for dragging and dropping, I can assist you further!
