President Roosevelt helped end the Russo-Japanese war with the Treaty of Portsmouth. To arrive at this answer, you can assess each of the options provided:

1. The Great White Fleet: The Great White Fleet refers to a group of United States Navy battleships that conducted a global circumnavigation in the early 1900s. While this fleet was influential in demonstrating America's naval power, it was not directly involved in ending the Russo-Japanese war.

2. Gentlemen's agreement: The Gentlemen's Agreement refers to an immigration agreement between the United States and Japan in 1907, aimed at reducing tensions and addressing discriminatory policies against Japanese immigrants. This agreement was unrelated to the Russo-Japanese war.

3. Spheres of influence: The concept of "spheres of influence" refers to a geopolitical strategy where powerful nations exert their control over weaker regions. While this concept played a role in several conflicts during the era, it is not directly connected to the end of the Russo-Japanese war.

4. The treaty of Portsmouth: The Treaty of Portsmouth, signed in 1905, was the primary instrument used by President Roosevelt to end the Russo-Japanese war. Roosevelt played a pivotal role in mediating the negotiations and bringing the two sides together to sign the treaty.

Therefore, the correct answer is the Treaty of Portsmouth. President Roosevelt's efforts as a mediator helped bring an end to the Russo-Japanese war and resulted in the signing of the treaty.
