Question 1
What are the minimum and maximum distances of the service holes from the ends of the beam?
A.	minimum = 1.2 m, maximum = 1.5 m
B.	minimum = 1.5 m, maximum = 1.75 m
C.	minimum = 1.5 m, maximum = 2.0 m
D.	minimum = 2.0 m, maximum = 2.5 m
The correct answer is C - minimum = 1.5 m, maximum = 2.0 m. The minimum distance is 1.5 m and the maximum distance is 2.0 m.

Question 2
What is the recommended depth of the service hole?
A.	300 mm
B.	200 mm
C.	100 mm
D.	50 mm
The correct answer is C - 100 mm. One third of 300 mm is 100 mm.
