The correct answer to this open question is the following.
Although the question does not include options, we can say that Rodina was like Pangea in that both were ancient and big supercontinents million years ago.
Historians think that Rodina was a supercontinent 350 million years ago. The intense heat of the earth made the surface of Rodina to stretch, and this weakened the crust. And the continent split.
Something similar happened many years after with Pangaea. The fragments of Rodinas's split started to unite again, slowly, through the years, to form the huge continent Pangaea in the Paleozoic times.
