The year 2021 is associated with which event in the material?

• A. The year after the phrase 'Montesquieu'
• B. Presidential term starting in that year
• C. The year following the 'Last six American president' line
• D. Inauguration of Joe Biden

Answer: (D)

The year 2021 is tied to Joe Biden’s inauguration. In the United States, the president’s inauguration occurs on January 20 following the election year, and Biden was sworn in as the 46th president on January 20, 2021. This event marks the start of his term and is the specific, widely recognized moment associated with that year in the material. The other options don’t point to a single, clearly identifiable event for 2021 in the same way, whereas the inauguration directly pins the year to Biden’s start in office.
