December 2006 Questions 11-15 (its from PowerScore LG Bible PAGE 159)
The book does explanations to each questions but I still DON'T GET IT! Please help a 0L out...
Question goes:
A locally known guitarist's demo CD contains exactly seven different songs - S, T, V, W, X, Y, and Z. Each song occupies exactly one of the CD's seven tracks. Some of the songs are rock classics, the others are new compositions.
Conditions as follow- S occupies the fourth track of the CD. Both W and Y precede S on the CD. T precedes W on the Cd. A rock classic occupies the sixth track of the CD. Each rock classic is immediately preceded on the CD by a new composition. Z is a rock classic.
According to the book's solution, the diagram set up for Song is:
(T>W,Y) S (V, X, Z)
1 2 3 4 5 6 7
My first question here is that obviously, I know that T W Y cannot be placed in 5,6, 7 but there's a possibility of V X Z being included in 1 2 3 sequencing. Why can't V X Z be also placed in 1 2 3?
Also: The rule #5 explains: R -> NR
and thus the book sequences Type as: N _ _ _ N R N
Why is this the case? I know 1 is N because through Now Laws rule R comes off in 1 making N, but why is 7th N? Can't that be also R? When I first solved this, I just put all the sequencing as N _ _ _ N R _
because the rule clearly says that whenver there is R it's N preceding R so 7 is empty because the rule is irrelevant to 7 since it doesn't talk about what comes after R
Yea, pretty frustrated... Help me out guys
Thanks a bunch
