I assume one is ineligible for this contest if one knows the meaning of "cullet" without looking it up. I am inclined to disqualify myself on this basis but there are so many entries, perhaps it is permissible to feign ignorance of the meaning of the word.

Can one feign ignorance by choosing correctly, passing the choice off as random chance?

If one feigns ignorance by choosing incorrectly, how can one hope to win this game?

A very perplexing challenge you have presented to us, Bingley.
