I didn’t know at all IDB(Inter-American Development Bank).
We met four Japanese in the building, and they explained the history, objectives, and activities of IDB to us in Japanese.
The main role of IDB was supporting the development in South and Middle American countries by loan and giving knowledge.
In the afternoon, National Portrait Gallery was so interesting for me because I saw a lot of portraits of American presidents.
I was interested in the presidents in the 20th century, such as Franklin D. Roosevelt, Harry Truman, and John F. Kennedy.
I bought three postcards of them in the gift shop.
