The statement that does NOT describe the 20th Amendment is:
D. It allowed FDR to be elected four times.
The 20th Amendment, ratified in 1933, primarily addressed the timing of presidential and congressional terms, shortening the period between the election and the inauguration of the president (hence the nickname "Lame Duck Amendment"). However, FDR's four elections were facilitated by the lack of term limits, which were later established by the 22nd Amendment in 1951. The 20th Amendment itself did not allow for the four-time election of FDR.
