Puzzles and Riddles

Aaaah...that makes sense. I think you have it.

That's right. Now, since you kind of got it between you, who goes next?

Neila came up with the idea of using water rather than poison, and all my hypothetical flailing around was based on that (also I don't have a riddle lined up ready to use anyway), so I'd say she gets the next one.

I only have one more set aside right now:

"It's the only thing where you can remove the whole, and some will still remain."

A mixed numeral - take away the 'whole' number and you're left with the fraction?

Nope! Creative answer though.

...a number divisible by ten? (Or any base of a system of counting, I suppose.) Take away the whole of 10 (for instance) and you're left with 0, which is part of the numeral '10'?

Or do I need to get away from thinking about numbers entirely? :)

Ah, it's a linguistic joke. The answer is wholesome, in the human language called anglish it's formed as a compound composed of the words for whole and some.

(Clever girl! But I've got a human ringer on my side, and a native anglish speaker too!)

Yup, you've got it.
Now I'm going to have to get some more before I try for another turn.

Fantastic, here's a quick one. More of a joke, really.

A C-Sec officer is staking out a small, empty residence, along with a civilian witness, a famously gifted if eccentric mathematician.

Two suspects are witnessed entering the building, after a period of time, three suspects are seen leaving. The officer is surprised by this, but takes the initiative and moves in to investigate but the witness stops her.

The witness insists that the residence is not empty. How has he deduced this, and what must happen before they can be sure it is empty and therefore safe to enter?

Another suspect must enter the building.

Is it that joke where something has to be added to create a 0 again?

Yes! Exactly so!

... it's a dumb joke...

Ha, thank you.

I have a maybe equally silly situation to solve:

I am driving driving a two-seater skycar on one big stormy night in the outskirts of nowhere. I pass a public transport station. There are three people who are waiting for the monorail: One old sick Matriarch who is dying, One doctor who saved my life before and is working on her now, and one Maiden who is someone I have been dreaming to be with.

I can only take one passenger, who should I take or leave to die?!

You stay with the maiden and let the doctor take the Matriarch to help.

Ugh, that was too obvious.
You are next, dear.

Four men sat down to play. They played all night til the break of day. They played for cash and not for fun, with a separate score for every one.
What are the four men playing?

This has got to be a wordplay one - Sarah posting about playing her cello (in another thread) gave me an idea, are the four men playing instruments rather than a game? And they have different 'scores' in the musical sense?

Instruments, in a band, etc...
Anything that falls under "music" works, really.
So you've got it. Next!

Yay! Okay, had one ready this time (see if you can beat Ana's time of about half a second - she may have heard it before, but I like the mystique of not knowing)...

You have been exploring ancient ruins on Tuchanka, and unwittingly stumbled into a well. The room at the bottom has only two exits: one leads to a large chamber containing a hive of klixen, the other is empty, but in its ceiling is a huge lens focusing the brutal rays of Aralakh into a beam that will boil you alive in the time it takes to get through it. How do you escape?

(For the purposes of the riddle, assume you're not one of those film badass archaeologists who could just kill the klixen.)
