Made it to question 4 and blew it by choosing "logically" between the two middle answers.
Arrange these monuments by the order in which they were dedicated, starting with the earliest.
1. Vietnam Veterans Memorial
2. Jefferson Memorial
3. Washington Monument
4. Lincoln Memorial
3-2-4-1 *bzzzt*
The years: 1982, 1943, 1885, 1922
I should have remembered from before -- by question 4, the "logical" order (by presidential term, in this case) is almost always the wrong order.
