ANSWERS
1. Mexico City was the site of what capital city of the Aztec Empire?
(I'll be as generous as possible with the spelling.)
Tenochtitlan. Try as I might, I couldn't accept "Xatapiciaixia" or "RJUJNBTYYFGHBYUYKG" as alternate spellings of that!

Quetzalcoatl was the Aztec sky god, not a city. And since there were a number of Aztec cities beginning with 'T', "T????????????????" was slightly insufficient.
2. In November, 1968, The Beatles released an LP known by what "colorful" name?
The White Album. Wikipedia says Yellow Submarine was not released until January 17, 1969, but it was recorded in 1968 and the movie was released in 1968. Since you know, through my pitiful knowledge of pop music, that I didn't intend to have such a wicked distractor, I'm giving credit for this answer, too.
3. Mole poblano is a sauce used in Mexican cuisine, made from dried chile peppers and what other, signature ingredient?
Chocolate was the signature ingredient I was looking for, but the recipe also includes various nuts and seeds, including peanuts, so points for them, too.
4. At the 1968 Summer Olympics, American athletes Tommie Smith and John Carlos were banned for life by the IOC after making what gesture during the 200 m. medal award ceremony?
They raised their black-gloved fists in a "Black Power" salute.
