Explanation:
1. We use the definite article "the" before countries that have the words "Republic," "Kingdom," "States," etc.
2. Rivers, seas, oceans, and peninsulas usually take the definite article "the."
3. Mountains and waterfalls do not take an article, so no article is needed for "Mount Everest" and "Niagara Falls."
4. Cities and regions do not usually take an article, so no article is needed for "Oklahoma City."
5. "Holland" is an exception and does not take an article.
6. "East Borneo" does not require an article because "East" acts as an adjective describing the location of Borneo.
