mc5 - AVMA Take 2

Yes, it's another round of that classic guessing game - Animal, Vegetable, Mineral, Abstract [or any combination thereof]. This effort - '03/'04 should address any queries, but then again, may just serve to confuse and baffle which some might say is the point of the game. Patience, integrity and a decent search engine may be useful ....

Projoy

Are any non-plurals in this set?

CdM

I'm having fun here

Contents change over time? I suppose they do, yes, but I don't think that is very helpful. The contents of the set are not in the set, by the way.
Any non-plurals in the set? YES. Non-plurals are not in the set, though.

Raak

The set of all things beginning with P?

Phil

The set of all things that have not been mentioned in this game

CdM

We have a winner!

The set of all things that begin with P is indeed the answer. Raak is now in possession of a passed baton

This reminded of me of the time I chose 'Human Construct' as an AVMA subject -- then, as now, everyone oddly failed to ask the standard question, making the quest much more difficult than I expected.
