The best interpretation of the two flat portions of the graph is: **These show where changes of state are occurring.**
In a temperature vs. thermal energy graph, flat portions typically indicate phases where temperature remains constant despite the addition of heat energy, which corresponds to changes of state (such as melting or boiling) where thermal energy is used to break molecular bonds rather than increasing temperature.
