Which problem do mail carriers in remote areas of Costa Rica, and some areas of the United States, face?%0D%0A(1 point)

One problem that mail carriers in remote areas of Costa Rica and some areas of the United States may face is the difficulty of reaching remote, isolated locations. These areas may have challenging terrain, such as rugged mountains or dense forests, which can make it challenging for mail carriers to access and deliver mail. Additionally, limited or unreliable infrastructure, such as unpaved roads or lack of transportation options, can further complicate the delivery process. This problem can result in delays or even the inability to deliver mail in a timely manner.
