There's a lot of dispute over why Constantine chose Byzantium as the new capital, but the general population seems to agree that it was likely because Byzantium was more easily defensible against attackers. The Balkans on the West proved difficult for attackers to pass over. Also the city was located on the water which not only allowed for trade via ships, it also allowed for naval defense.
The correct answer is: A. A city wants to review articles about its commission meetings before they are published in the local newspaper.
This case would likely implicate the Constitutional question of whether or not the state is restricting a free press, which is guaranteed under the first amendment.
Bartholomew Diaz, who was sponsored by Portugal, had just rounded the tip of Africa. Ferdinand and Isabella were desperate to find a way to India (Asia) before Portugal. They were looking for a new way to get there faster.
Columbus had already tried to go to Portugal, but, as said before, Diaz had just rounded the Cape of Good Hope, so Portugal didn't want/need a new idea.
Hope this helps! Please let me know if I'm wrong :)
