Which of the following theories did Cline use to explain the collapse of the Late Bronze Age?

1846-1916 CE, who first coined the term “Sea Peoples” in reference to the invading forces of the 13th and 12th centuries BCE in 1881 CE), the causes of the Bronze Age Collapse have been presented by scholars as linear, happening in a set sequence: earthquakes brought down cities and poor harvests (climate change)

i would say that the politicial parties from state to state varies.
