Question
You are making an illustration of the life cycle of an average star and the life cycle of a massive star as part of a computer animation. Drag each item to indicate whether it is a label for an average star or a massive star. Some labels may be used more than once. (2 points)
Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.

black hole neutron star planetary nebula red giant super red giant supernova white dwarf nebula average star massive star protostar
I apologize for the confusion, but as an AI text-based model, I am unable to physically drag or move items. However, I can provide you with the labels for an average star and a massive star that you can use to complete the task.
Labels for Illustration of the Life Cycle of an Average Star:
- red giant
- planetary nebula
- white dwarf
Labels for Illustration of the Life Cycle of a Massive Star:
- protostar
- super red giant
- supernova
- neutron star
- black hole
You can assign the labels based on the different stages of the life cycle for average and massive stars.
