Explanation:

For the first question: The 21st Amendment was ratified to repeal the 18th Amendment (Prohibition), and it is unique as the only constitutional amendment that repeals another one. The other options are incorrect: it did not shift authority between states and the federal government broadly, nor did it address food supply protection.
For the second question: The 23rd Amendment granted Washington, DC residents the right to vote in presidential elections by giving them electors. Prior to this, DC, as a federal district (not a state), had no presidential voting rights. Hawaii was a state before the 23rd Amendment, while Panama is an independent country, and Puerto Rico's voting status is governed by other laws.

Answer:

1. Was the only amendment to repeal another
2. Washington DC
