Final answer:
Franklin D. Roosevelt's presidency exemplified that disabilities do not preclude significant accomplishments, as he effectively led the nation as a disabled president.
Step-by-step explanation:
Franklin D. Roosevelt's presidency demonstrated that disabilities are not always a barrier to high achievement. Despite contracting polio a decade earlier, which left him paralyzed from the waist down, Roosevelt maintained a strong public presence and led the United States through the Great Depression and World War II. His disability did not deter him from his duties as President, and he went to great lengths to ensure that his physical condition did not overshadow his leadership, including managing the media's portrayal of his disability.
Roosevelt's experience illustrates how individuals with disabilities can and have impacted society positively when given the opportunity. This is evident not just in Roosevelt's story, but also in the broader historical context where the contributions of those with disabilities began to be recognized, notably with the civil rights movement for people with disabilities and the eventual passage of the Americans With Disabilities Act in 1990.
