Answer:
Rivers of the Coastal Plain were a major means of commercial transportation during the 1700s and early 1800s. Cities founded along the fall line, called “fall line cities,” are located at the places where these rivers crossed the fall line, marking the upstream limit of travel. The city of Columbus, for example, was established where the Chattahoochee River crosses the fall line; Macon, Milledgeville, and Augusta are similarly located at the crossings of the Ocmulgee, Oconee, and Savannah rivers, respectively. These cities became important transportation hubs because traders could only travel upstream until they reached the waterfalls of the fall line. At that point they were forced to disembark and reload their cargo on the other side of the falls in order to continue their journeys. Columbus served as the upstream head of navigation for the Chattahoochee, as did Augusta for the Savannah River and Macon for the Ocmulgee River. After the first steamship arrived in 1828, Columbus became a gateway city for cotton. Above the fall line, flatboats and barges moved goods around the state. Below the fall line, steamships had unimpeded access to move goods, mostly cotton, into the Gulf of Mexico.
The country of Brazil & Bolivia are the pair which share a border.
The border in this context refers countries which shares a close or immediate boundary. For instance, the nation of U.S. and Canada shares a border.
Here, the pairs including "Belgium & Bulgaria", "Belize & Barbados" and "Belarus & Bangladesh" does not share a boundary.
Hence, the country of Brazil & Bolivia are the pair which share a border.
Therefore, the Option B is correct.

Salutations!
The Earth is closer to the sun during summer in the Northern Hemisphere than it is during winter. True or False?
True. The Earth is closer to the sun because during the summer, the sun rays are directly hitting towards the Northern Hemisphere which makes it hot. During the winter, the sun rays are not directly hitting, thus, its cooler in winter than in the summer.
Hope I helped :D
