Answer 1

The best interpretation of the two flat portions of the graph is:

These show where changes of state are occurring.

In a graph representing temperature versus energy, flat portions typically indicate that the temperature remains constant while a substance is undergoing a phase change (e.g., melting or boiling). During these processes, energy is being absorbed or released, but the temperature does not change until the phase change is complete.
