Dear fellow test takers & staff,
I am looking at the Drill It : 3D ordering Setups question 4. (page 191 & solutions on page 192).
My question is : why is there a 60 minute program necessarily in the last (6th position)?
Briefly summarizing question 4:
4.
Six programs : M, N, O , P , R & S
No two programs are broadcast simultaneously & no other programs are broadcast.
Each program is 30 mins or 60 mins.
R1: N is 60 mins
R2: S immediately precedes O
R3: Each 30 min program is immediately followed by a 60 min program
R4: P is broadcast at some time before O
R5: A 30 minute program is broadcast fourth
Again based on the above why must there be a 60 minute program in the last slot?
It does not say that a 30 minute program must necessarily be followed a 60 minute program. If that were true then it would make sense but maybe I am missing an inference?
Sincerely,
Arthur
