Which building still exists as a testament to the creative achievements during the 1893 World's Fair?

The Museum of Science and Industry is a significant structure remaining from the 1893 World's Fair, also known as the World's Columbian Exposition. Originally, the building was constructed as the Palace of Fine Arts for the Fair, showcasing the creative spirit and architectural innovation of the time. Designed by architect Charles B. Atwood in a neoclassical style, the building was later repurposed to become the Museum of Science and Industry, which opened in 1933.

The museum continues to serve as a prominent cultural institution, featuring exhibits that explore science, industry, and technology, aligning with the Fair's original goals of education and innovation. Its preservation is a reflection of Chicago's rich history tied to the World's Fair, making it a true testament to the era's creative achievements.

While other options may represent important institutions in Chicago, they do not share the direct historical connection to the 1893 World's Fair that the Museum of Science and Industry does.
