What major change did constantine bring to byzantium?

Constantine the Great was the Roman emperor from 306 to 337. From 324 he ruled as sole ruler.  

Constantine's rise to power took place in the context of the dissolution of the Roman tetrarchy, which Emperor Diocletian had established. In 306, Constantine inherited his father Constantius I after his soldiers had proclaimed him emperor. By 312 Constantine had prevailed in the west, 324 also in the entire empire. His reign was particularly important because during his term Christianity's rise to become the most important religion in the Roman Empire began. Since 313, the Milan Edict guaranteed freedom of religion throughout the empire. Subsequently, Constantine privileged Christianity, paving the way for it to become the official religion of the Empire. Inside, Constantine pushed ahead with several reforms that shaped the empire during the late antiquity. In terms of foreign policy, he succeeded in securing and stabilizing the borders.

explanation:

the sentence that best describes the tone of the passage from the radio broadcast compared to the passage from the book is b. the radio broadcast has a more surprised tone.

consider the text evidence: in the passage from the book, the description is more matter-of-fact. it is simply describing the things resembling little grey snakes, but there is no urgency in the description. on the other hand, in the passage from the radio broadcast, there is definetely urgency (you can tell from the expression used, "good heavens", which clearly indicates surprise.)
