Prep Test 31, Section 3, Q18/Q26

Postby zdamico » Mon Aug 15, 2011 2:08 pm

These are the only two I got wrong, and I still can't quite figure out why the answers for 18 and 26 respectively are A(18.) and B(26.) instead of D(18.) and C.(26.)

I think the trick of 18 is to read the question. this is not a parallel flaw question. D is a flawed argument, A is logical.


When I tried to do it just now, I immediately crossed out A because I was looking for a flawed argument instead of a logical one.
[irrelevant]IMO, the argument in the stem is BS. Just because science requires something which is arbitrary doesn't mean that science itself becomes arbitrary. You can do the same science with any arbitrary unit of measurement and then arrive at exactly the same result since the units are just an abstraction.[/irrelevant]

26, I think the key word is dialogue. The suggestions for improved efficiency may not have been the result of a dialogue, the employer may have just come up with them on his own. C is too specific.

Both of these were tough though. I'd be curious if anyone else has anything to add.

Thanks very much. You totally cleared up 26 for me, I see now that the key word is 'believe', and the lack of that word in C. is what kills it. 18 I understand a little better, but I still am not completely comfortable with.

Thanks for the help!

Did you read in PS that if the question does not explicitly tell you to look for a flaw, that it means that the logic is valid?

That means you can automatically negate any answer choices which use flawed logic, D being one of them.

Be careful about this. There have been questions in the past where the stem doesn't indicate a flawed argument, but the argument itself is still flawed.

really? Is that a new thing? Maybe I need to go back and reread the Bible.
