June 2000 ptest 31, game #2 new used CD's Forum

[nStiver]

Ok, I am having a hard time figuring this game out. This is the one about the new and used CD's on sale.

I am looking at the Powerscore "ultimate setup guide", and they are saying that used pop MUST be selected. They simply treat this inference as self evident and build the rest of their explanation upon it. I have reached my point of frustration with this game. Can anyone else who has the LG setup guide explain this to me? I plodded through the game under timed conditions and somehow got 5/7 answers correct, but I am trying to actually understand it.

P.S. The setup guide can be a useful tool, but it is oversights like this that disappoint me. I understand that the setups are just brief overviews designed to help you diagram the rules and point you in the right direction. However, it really seems like the authors didn't spend the time that is necessary to produce a quality product.

used pop MUST be selected

this is a rule - not an inference. the first rule says used pop is definitely in, and new opera is definitely out.

this rule is not a conditional statement (look at the semicolon, and note that there is no "if" starting off the sentence).

common mistake.

Ha, my mistake then. Thanks
