Answer and a Blast from the Past

The answer to yesterday's question was A) Yes. The idea is that if Anne is married, she is looking at an unmarried person, and if, on the other hand, she is unmarried, she is being looked at by a married person (in a most chaste way, presumably).
Apparently, smart people who are able to optimise their thinking to allow more efficient cogitation, are loathe to consider both of these two possible scenarios, and therefore answer that there is not enough information.

On an entirely different note, this video of London in colour from 1927 is absolutely amazing. It's almost the same, but with a touch of the cities of SE Asia about it; lots of handcarts and street vendors. Enjoy.
