I think the reason I did so badly is because I took the instructions to mean that I should take all nonsense as sense and go from there.

The instructions were not very clearly worded and assumed the reader was already familiar with the formal construct of deductive logic, that is to say: premise 1; premise 2; therefore conclusion. And familiar with what one is to do with the premises, how one deals with false premeses, etc. There was a lot of assumption on the part of the test composer(s) as to the background knowledge of the potential test takers.

87%, no wait 93% (I don't see how those with 100% have been able to figure out the question 12, or 14 for that matter.).

Question 12 relates to words meaning multiple things.

It can be reworded:

What rises must fall.
The burglars woke up ("before the beak", whatever that means).
Therefore, the burglars will be arrested.

Number 14, it relates to understanding the metaphor in the first premise. "inside every fat person there is a thin person trying to get out." does not mean there's a separate 2nd person inside that person.

Also, just because George Orwell says something is so does not make it so. The premise is not "inside every fat person there is a thin person trying to get out.", but that someone said "inside every fat person there is a thin person trying to get out.".

Having gotten the questions right, though, does not mean they figured them out. There is, after all, a 50/50 chance of getting each one right by guessing. 25% (on average) of people guessing on those two questions will get them both right.

I did understood the explanations. What I don't get is how some have been able to figure out the answers without more indications. I'm not smart enough to have figured that on my own, I guess.

The test isn't very good. It implies that you should ignore the semantics of the words, or at least is ambiguous as to whether semantics matter or whether it's purely a formal/syntactic logic that should be used.

Okay, correction:

What rises must fall.
The burglars are before the magistrate.
Therefore, the burglars will be imprisioned.

While, due to not knowing "before the beak" I misunderstood what the burglars are doing, still, it was clear the "are up" and the "go down" had nothing to do with the rising and falling of "what goes up must come down", thus I knew the argument was invalid.

What you are supposed to ignore is whether or not the initial propositions are true. Which, unfortunately, was not made clear in the instructions.

87%... which I don't think is that impressive really. It struck me as a very easy test.

My score was 80%
I don't know what "beak" means in this context.

Just to add... the score I gave above was for the second test. Just taken the first test (even easier) and got a hundred.

So, between the two I've got over ninety percent. I suppose I can now vote on the poll.

Maybe I misunderstood you but, even if what you say is true, it doesn't contradict what I said. In fact it could be used to validate what I said.

Gave up. Couldn't figure whether to take a lot of those questions literally or not. >.<

they did say this "Remember that the truth of the conclusion is not sought, only the validity of the arguments should be judged."

which i extrapolated to mean that none of the statements should be judged based on their real world validity, but they could've been clearer about it. (did i say that right? maybe i mean "from which i extrapolated ...")

anyway, once you read the test questions it becomes clear that the initial propositions can be fictitious- we all know birds aren't reptiles, for example. triangles don't have four sides.

I got 80%.

I found this test confusing because the premises are mostly nonsense statements. I also had trouble knowing how literally I was supposed to interpret the statements. I'm also a right hemisphere thinker so I don't do so well with word problems that have no concrete visual basis.
