Q. In a scheduling scenario, if task X must be completed before task Y, and task Y must be completed before task Z, which of the following sequences is valid?
A.
Z, Y, X
B.
X, Y, Z
C.
Y, Z, X
D.
Z, X, Y

Q. In a scheduling scenario, if task X must be completed before task Y, and task Y must be completed before task Z, which of the following is a valid inference?
A.
X can start after Y
B.
Z can start before Y
C.
Y can start after X
D.
Z must start after X

Q. In a scheduling set involving five friends, A, B, C, D, and E, if A cannot sit next to B, and C must sit between D and E, which of the following arrangements is valid?
A.
A, C, D, E, B
B.
B, A, C, E, D
C.
D, C, E, A, B
D.

A.
A, B, C, D
B.
D, C, A, B
C.
B, A, D, C
D.
C, D, A, B
Solution
The only valid sequence is D, C, A, B, as it respects the constraints given.
Q. In a scheduling set, if task E must be completed before task D, and task D must be completed before task C, which of the following sequences is valid?
A.
C, D, E
B.
E, D, C
C.
D, C, E
D.
E, C, D
Solution
The sequence E, D, C respects the order that E must be completed before D, and D must be completed before C.
Q. In a scheduling set, if task G must be completed before task H, and task H must be completed before task I, which of the following sequences is invalid?
A.
G, H, I
B.
H, G, I
C.
G, I, H
