he way I understood it none of the questions required/allowed you to use outside understanding
actually, they all do. without outside understanding, you can't tell nouns from verbs from prepositions from adjectives. you don't know what it means to "bark" (does it mean to make a noise like a dog, or to be a dog?). the problems happen when the trick in the question gets too close to the things you have to know to understand the question itself. evs
a.) All shizzywigs blurgle. b.) Plurlp is a shizzywig. Conclusion: Plurlp blurgles. You do need to know the language of propositional logic. THAT'S IT. Do you consider knowing what "+", "-", "*", and "/" mean to be outside information when determining the answer to a math problem? This is a test of your ability to read, understand, and properly apply the language of propositional logic. To complain about needing to understand what's being tested is just.... just.... Please don't force me to finish that insult.

Okay, I concede that you may need to use some outside understanding

to come to a conclusion for that question... Question 7. a) All ducks bark. b) Donald is a duck. Conclusion Therefore Donald barks. All I need to know is that all ducks do it and Donald is a duck so he must do it, whatever "it" happens to be isn't really important to the question.

Very well: you want a more verbiose answer? Frankly, I'm having trouble deciding whether you passed that question without realizing it, or failed it miserably. Regardless of which answer you selected. You spoke rightly when you said that

based on the premises alone, we can't validate the conclusion.
That was the point of the question: based on the premises alone, you can't validate the conclusion. Thus the conclusion is invalid. Thus the answer key says the answer is invalid. You did read the answer key, right? Though the answer key (as previously noted) is not very good. And it does show in this question as well: It would have been so easy to point out that the premises said nothing about understanding. The author could have pointed out that the premises were nonsense statements in the first place (though that would have required pointing out that this is irrelevant to the strict application of logic). The author should have pointed out that there was absolutely nothing in the premises to support the proposed conclusion. But instead, the author supplied evidence outside of the logical structure to show (empirically), rather than show (logically) that the conclusion was wrong, rather than invalid, as was intended. Thus, in the context of the answer key, the question was bad, because the author failed to explain the logic; but in the of the test itself, the question was perfectly valid: it requires you to ignore, rather than import, outside knowledge, in order to correctly determine that the conclusion was not, as you stated, supported by the premises.

and i don't remember if i got the Mars/Venus one right or not (i got the Paris one right, i know). i took the test hours before you commented on it here. i missed two, i think. but the quiz doesn't tell you which you missed and which you didn't. it just gives the answers. but regardless, i picked these two for examples here because they fit the point i was trying to make. which i guess i failed to do.

ok ok. ducks and barking was a bad example. i guess it's the Venus/Mars one that really gets me. let me try it this way: both of the statements are nonsense, so of course you can't draw any conclusions from them. but in order to know they are nonsense, you really do have to know a bit about Men, Women, Mars, Venus, "from" and "understanding". and, yes, i understand why the answer to that one is what it is. i just think that one, and a couple of the other questions, are a touch sloppy.

I think you are over thinking it here. Question 11. a) Men are from Mars. b) Women are from Venus. Conclusion Therefore men and women will never understand each other. You don't need to know they are nonsense, you just need to know that nothing was said about understanding in the facts given, the only thing mentioned is where they are from, so therefore you can't really draw any conclusions about anything other than where they are from. Certainly not about whether they understand each other or not, and this is what makes the conclusion given invalid. IMO. :)

Tough crowd :(( What kind of items can I invent to make it more interesting? I held off on this year's Darwin Awards winner (for fear of offending folk), all the Apple news (really, $179 to replace the battery, and 30c/song I already paid you for?), and a game site (figuring you hard-working folk wouldn't appreciate the distraction).

Did anybody else notice, in the Logic Test[^] linked to in the Insider, that the person who wrote the answers to the test[^] used the wrong logical visualiations? In the explanations for the first two answers, the Venn diagram was used (without any any indication of what was and was not a valid zone, mind you), when clearly what was intended was to show that
do ⊆ d ⊆ q
and
female logicians ⊆ clear thinkers
AND
lawyers ⊆ clear thinkersIn each case, Euler diagrams should have been used, showing the subsets wholly contained inside the supersets, as shown in the Wikipedia entry on Venn diagrams[^]. Venn (and Euler) diagrams are supposed to make the visualization of logic easier, but this article does nothing to aid in said visualization - in fact adding to the confusion, especially in the first question, where the Venn diagram clearly shows cases of Donald not quacking, and only the (completely unexplained) presence of a red X shows us that there is some significance to the intersection of all three. Which significance is unexplained in the diagram, and passed over in the commentary. I can only assume that the inclusion of an article about logic with such a glaring flaw placed so prominently must be the result of our esteemed editors being tied up by an evil, evil monkey and forced to watch in horror as the monkey (I'm not adding monkey as a suffix to another word, so it's still okay, right?) proceeded to send the Insider with one mistake in it. I hope that was the only mistake in it, anyway! Perhaps the fact that there were so few interesting links in today's episode were another? I hope everyone else scored 100% on the test, like I did, though. :cool:
Yeah, 100%, but I don't like their explanation of 15... 0) In my opinion, statement b is unnecessary. 1) Even though water is H2O, some future observation or examination may use mis-calibrated equipment or user error. 2) Their explanation about some other water-like compound doesn't apply.
