franklin roosevelts attempts to change the role of government were somewhat restricted by his \brain trust.\…

Brief Explanations:

Franklin Roosevelt's New Deal policies aimed to expand government intervention. However, the Supreme Court initially struck down many New Deal programs, arguing they exceeded the government's constitutional powers. For example, in Schechter Poultry Corp. v. United States (1935), the Court invalidated the National Recovery Administration. This judicial opposition restricted Roosevelt's efforts to reshape the government's role. The "brain trust" was a group of advisors who supported his policies. The Great Depression was the context that led to his attempts, not a restriction. His paralysis affected his mobility but not the policy - making restrictions in the way the Supreme Court did.

Answer:

the Supreme Court.
