| And since I'm being technical here, carat with a "c" is used in the weighing of gems, and karat with a "k" is used in the purity of gold. I don't remember the episode, so I don't remember the context of Robin's exclamation. However, in the use of the clue, karat is the only response required, technically. If Robin used it in reference to gems, however, this would be an incorrect clue and response. |
