GCHQ (the people who spy on the citizens of the UK for David Cameron) have released a Christmas Card this year, which is a puzzle which leads to more puzzles.

http://www.gchq.gov.uk/press_and_me...uzzle-2015.aspx

We can solve it.


Solution 1: http://i.imgur.com/50H7nyM.png leads to http://www.gchq.gov.uk/puzz/Pages/index.aspx

Solution 2: the answers are d e f a c e and lead to http://s3-eu-west-1.amazonaws.com/p...3f70e45b3d.html

Solution 3: the url itself is a spoiler so don't look at it if you want to try the puzzles for yourself: http://www.cub-zone-often.org.uk/layered/

Solution 4: same as 3, the url is a spoiler for the previous section: http://www.gchq.gov.uk/58aa7ef96f3051b0/Pages/index.aspx

The Saga


Aston and me started working on this on IRC (I solved the Picross puzzle because I am a hopeless Picross addict), and we've at least narrowed down the answer to the first question to be either SHALLOT or SUGGEST. Note that the question is to pick the one that is not the odd one out - and the other ones are. STARLET is the only one lacking a consonant pair, SONNET is the only one that's 6 letters rather than 7, SAFFRON is the only one that doesn't end with T and TORRENT is the only one that doesn't start with T.

We looked at the colour question for a while as well, but came up with nothing.

SHALLOT doesn't have an E. The correct answer is SUGGEST. The number sequence question is the one that's bending my brain.

I'm not sure what's confusing you. You can make a set of rules which exclude only one answer (e.g. must start with "s", double repeating consonants, ends with " T"). The one you can't exclude is the correct answer.

What is confusing me is I can make a set of rules that would exclude any one of them. Why is the correct answer on the first question 'Shallot' and not one of the others? If it isn't 'the odd one out' then how come it is the only answer with the letter 'h' in it?

My point is the 'right' answer is completely arbitrary unless the entire point of the exercise is to end up with a set of answers that read out 'deface' at the end or some dumb meta poo poo like that.

Then your rules were incorrect. It's not soley an iq test... For the colour question I could have arbitrarily said the colour order were the candle colours on my nephew's birthday cake. The answer might be correct but it wouldn't be globally applicable or correct in this case, and you would need personal a priori knowledge.

For the first question, what rules do you have to make another word not the odd one out?

I see only one set of rules to satisfy the question.

For the first question, whT rules do you have to make another word the odd one out?

If I have to find one that ISN'T the odd one out then there are tons of rule sets that work. If I'm trying to find a word that IS the odd one out then that's easy, too.

The question is 'what word is never the odd one out no matter what set of rules you come up with' but that's dumb because as I said I can come up with a set of rules to make any one of them the odd one out. And Shallot can't be NEVER the odd one out because it is the only one with an 'h.'

To answer your question (what rules do I have to make another word the odd one out), 'suggest' is the only answer that has a 'u' in it so I could say 'any word without 'u' is part of the set.' You can also get more esoteric with it and say things like 'starlet' is the only word describing a human - since they are vague with the question I see no reason that I have to keep the 'correct' answer strictly to letter/grammer/word rule sets like we've been doing (shallot is the only onion variant plant on there for example, which again makes it 'the odd one out').

spud posted:

Yeah that's my point, and their correct answer also needs some personal a priori knowledge. 'This case' is just whatever the questioner decides is right.

This particular question was just constructed poorly.

Not the odd one out = commonality with some others. The question is asking which word is NOT the odd one out (ie you can't come up with a ruleset that would exclude it from the others thus it is never the odd one out). Right?

The actual answer given those parameters is 'none of them.'

I didn't miss the NOT, it's the reason why the question sucks. Their logic is muddled.

None of them wasn't a choice though,which bounds the problem space massively. I would completely agree with you if the question was open ended.

When you work it through, Shallot is the only answer.

But shallot can't NOT be the odd one out, it has an 'h' and none of the others do so therefore it can't be a correct answer to their question given a very basic single rule I came up with to define a set (a set containing all answers without the letter 'h'). Plus, I can come up with a rule that would exclude any one of the others which means none of the answers can't NOT be the odd one out. Do you see my problem? The only way I'd know what was 'really' the correct answer is to know what the questioner is thinking.

I see what they were going for but they flubbed it, is all. If 'none' is the correct answer then it doesn't matter if it is a choice on there or not; the question is incorrect. They ask you a question that has no correct choice in the answers.

The question is basically 'Which answer can NOT be contained in a set by itself?' and the list of answers doesn't provide an option to fit that because they give you no instructions that define the bounds by which you can define the set and thus any of the answers could be made to fit.

Saying 'shallot' is NEVER the odd one out but having it be the only choice with an 'h' in the spelling is kinda to me but maybe I'm just not seeing something. Like why 'shallot' and not 'saffron' for instance? Because saffron is the only one that ends with an 'n?' But then what about the 'h' in 'shallot?'

You aren't thinking outside the box.

The H in Shallot is just like the U in suggest. What makes suggest different from shallot? Instead of trying to make a global set of rules based solely on the letters in each word (I did this, coming from a comp sci background, and its the wrong way of thinking), compare each word with every other and try to eliminate one of the pair.

Hint: you need meta data,i.e it's not just about the letters in each word.

Answer: Suggest is not a noun, therefore different

E. Saffron ends in n, therefore unique.

Holy crap I laughed... Was this coincidence that it is art within art or what?

See but... that's what I mean. These 'think outside the box' questions are really just 'what am I thinking' most of the time.

I get how the H in 'shallot' is like the U in 'suggest' - it's a unique letter. And I get how shallot is different than suggest (noun vs verb). But I don't see how that makes shallot NOT the odd one out. It seems like that in fact makes shallot unique versus the others and I can put it in a set of 1 by itself and therefore it can't NOT be the odd one out. The fact that it is a noun with a second letter than none of the other words start with or share makes it the odd one out.

Furthermore, it's some bullshit 'lol what am I thinking' to say 'Saffron ends in N and is therefore unique, but the fact that Shallot is the only answer with an H as the second letter is irrelevant.'

The question just sucks and the fact that they gave us a limited set of answers to work backwards from doesn't make it any better, really.

Oh, you are still comparing each word over the entire set. That does not work. It's on a pair basis.

E. You are loving killing me man, im typing all poo poo this on my phone. Start with the basics : one word is 6 letters long, the rest are 7. No matter how you slice it, that word is different. There is an order of preference for elimination.

I did that and for every possible permutation there's a commonality, therefore NONE of them could ever be the 'odd one out' therefore the question doesn't work.

F - E: both have double consonant              E starts with 't'
What makes 'shallot' uniquely common such that it can NEVER be the odd one out and is the correct answer versus one of the others? The question asks 'Which of the following can NOT be the odd one out?' (ie, which of the following ALWAYS shares some commonality with another word) and there is nothing particular about 'shallot' to give it that distinction.

Every single pair has both a commonality and a difference so how the hell is anyone supposed to definitively be able to say which word can NEVER fit in a set by itself unless they know what the questioner is thinking? NONE of those words can not be the odd one out.

Maybe I'm just fundamentally missing something. And again the very fact that 'shallot' has a letter that is unique to itself versus the other answers (H) makes it possible that 'shallot' can be an odd one out so how can it be the right answer? It's just whatever they decided was the right answer but there's no real objectively correct answer in that list.

Ok I broke out the loving laptop for this:

YES! STOP COMPARING THINGS GLOBALLY YOU ARE loving KILLING ME.

If you compare A to B, make a decision, and then one is gone.

Now your set is reduced to 5 options.Then 4, then 3, and so on.

If you hit a dead end, expand back to 6, and start with comparing A to C, and then work on as before.

In all your examples you just compare everything to everything else, trying to make some global ruleset that you can just apply regardless of what you are comparing to whatever else, and i've said at least 3 times, stop doing that.

As a human you can shortcut this, by seeing for example, that SONNET only has 6, and all others have 7, so no matter which 2 you start comparing, the answer is the same: B is gone. This is called COMMON SENSE. You can also do this with TORRENT vs anything else. You rapidly end up with 3 possibilities.

This was one of only 2 easy questions I understood and could solve.

Well idk the other 3-4 people I just showed this to agree that the question is dumb.

Look: the question asks 'which of these is not unique in any way.' That's what 'can NOT be the odd one out' means. Shallot has a goddamn H and it is the only one that does. Either the question is worded weird or the list of answers is borked.

Global rulesets or individual pairs or whatever the hell, all it amounts to is 'can you GUESS what the questioner's logic here is?' and it's a poorly worded question.
