Re: Yes/No Answer
For me, "Yes" works fine in the original context. It doesn't matter how the sentence ends. The important part is "Does this mean that ...". Saying "Yes" means "Yes, it means that".
There are plenty of questions to which a straight Yes or No would not work but I don't think this is one of them. Had the question been "So you weren't planning to assassinate the king?", it would not be possible to answer with a simple Yes or No.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
