Question 1
Which is the first task?
A.     	Plaster walls
B.     	Internal joinery (cupboards, pantries, built-in robes etc)
C.     	Fix skirting boards, architraves 
D.     	Fit internal doors
E.     	Plumbing fit-off
F.     	Electrical fit-off
G.     	Painting
The correct answer is A - Plaster walls. This is the first task in this sequence.
This is then displayed as a circle with the figure one inside, node 1. From this node is a horizontal activity arrow labelled 'Plaster walls' indicating the duration of 5 days.
Question 2 
Which task(s) have plaster walls as a preceding event?
A.     	Internal joinery (cupboards, pantries, built-in robes etc)
B.    	 Fix skirting boards, architraves 
C.     	Fit internal doors
D.     	Plumbing fit-off
E.     	Electrical fit-off
F.     	Painting
The correct answer is A - Internal joinery (cupboards, pantries, built-in robes etc). 
This is displayed as node 2 joining the sequence in a horizontal line. The activity arrow from node 2 is labelled 'Internal joinery' with a duration of four days.

Question 3 
Which task(s) have internal joinery as a preceding event?
A.    	 Fix skirting boards, architraves 
B.     	Fit internal doors
C.     	Plumbing fit-off
D.     	Electrical fit-off
E.     	Painting
The correct answers are A - Fix skirting boards, architraves and D - Electrical fit-off.
This is displayed as node 3 joining node 2. From node 3 is a horizontal activity arrow labelled 'Fix skirting' with a duration of three days. Also from node 3 is an arrow which heads downwards then to the right labelled 'Electrical fit-off' with a duration of three days.

Question 4 

Which task(s) have fix skirting as a preceding event?
A.     	Fit internal doors
B.     	Plumbing fit-off
C.     	Electrical fit-off
D.     	Painting
The correct answer is A - Fit internal doors.
Node 4 connects with node 3 on a horizontal line and is labelled 'Fit internal doors' with a duration of three days.

Question 5 

Which task(s) have fit internal doors as a preceding event?
A.     	Plumbing fit-off
B.     	Painting
C.     	Gas inspection
D.     	Electrical inspection
E.     	Sewerage inspection
The correct answers are A - Plumbing fit-off and B - Painting.
Node 5 connects after node 4. After node 5 is the activity arrow 'Plumbing fit-off' with a duration of two days which heads upwards then to the right. Also after node 5 is a horizontal activity arrow labelled 'Painting' with a duration of ten days.

Question 6 
Which task(s) have plumbing fit-off as a preceding event?
A.     	Electrical fit-off
B.     	Painting
C.     	Gas inspection
D.     	Sewerage inspection
The correct answers are C - Gas inspection and D - Sewerage inspection.
Node 6 connects after 'Plumbing fit-off'. From here an activity arrow heads upwards and to the right labelled 'Gas inspection' with a duration of half a day. Also from 
node 6 is a horizontal activity arrow labelled 'Sewerage inspection' with a duration of half a day. 
Both of these arrows from node 6 then connect with a single arrow to a box labelled 'Completed'. This completes a sequence in the PERT chart.
Now return to an incomplete path. 

Question 7 

Starting at node 3, which task(s) have Electrical fit-off  as a preceding event?
A.     	Electrical inspection
B.     	Complete fittings and fixtures
The correct answer is A - Electrical inspection.
Another sequence is completed by adding node 7 after 'Electrical fit-off' and extending the arrow to the 'Completed' box. This is the final node which is then numbered 8. The final view of the completed PERT chart shows all the nodes from 
1 to 8 and the horizontal arrow after node 5 from 'Painting' is extended and now connects to node 8.
