LSAT QUESTION HELP!!?
I have noo idea how to go about diagraming these conditions to answer the questions like the one i listed below. Is there some kind of a chain or anything you can draw that will help answer questions?
A music store carries exactly ten types of CDs-both new and used of each of jazz, opera, pop, rap, and soul. The store is having a sale on some of these types of CDs. The following conditions must apply:
used pop is on sale; new opera is not
if both types of pop are on sale, then all soul is
If both types of jazz are on sale, then no rap is
if neither type of jazz is on sale; then new pop is
If either type of rap is on sale; then no soul is
#1. If new soul is not on sale, then which one of the following must be true…
a) new rap is not on sale
b) new rap is on sale
c) used opera is not on sale
d) at least one type of jazz is not on sale
e) at least one type of pop is not on sale
You are looking at one of the harder Grouping games to ever appear on the LSAT, the CD game from the June 2000 exam. To best diagram it, you have to use conditional arrow diagrams and be very well-versed in conditional diagramming. The PowerScore LSAT Logic Games Bible teaches how to diagram these games, and since there is normally at least one Grouping game per test, you will probably see one (or more) on your test.
In the case of question #1, you can use the contrapositive of the second rule to solve the question:
If new soul is not on sale (and thus NOT all soul), then the contrapositive of the second rule indicates that both types of pop are NOT on sale. So, E has to be the right answer (and you actually know from using the first rule that it is new pop that is not on sale).
I’m not sure if the terminology above makes sense to you, but if you are not familiar with ideas like the contrapositive, you have to learn how it works asap. It is all over the LSAT, especially on Grouping games like this one.
Good luck!
