- Usually, you encourage the parachutist to ask "What name would a liar give to
- the other city?". However, I am not convinced that this "works". It makes some
- assumptions about lying which are not clear. For example, it assumes (which is
- reasonable) that the honest people have noticed the "liars" and have come to
- some understanding of what is involved. However, what lying means to the liars
- is difficult to say, especially since they can't agree on it. Since the truthful
- citizens know this as well, they give you an answer which a liar would give you,
- but this is no use unless the liar's answer is well defined.

- Right?
