	a.	Some activities on the critical path may have positive slack
	b.	An activity on the critical path can have Early Start and Late Start times that are different
	c.	The longest path through the network is the critical path
	d.	Every network has exactly one critical path
	e.	The duration of the critical path is the average duration of ALL paths in the project network

  Which of the following statements regarding Gantt charts is true?

	a.	Gantt charts give a timeline and precise precedence/dependency relationships for each activity of a project
	b.	Gantt charts are expensive
	c.	Gantt charts are visual tools showing the timing and duration of activities in a project
	d.	Gantt charts use the four standard activities of Methods, Materials, Manpower, and Machinery
	e.	All of the statements listed are true

The network analysis in project management involves Forward pass and Backward pass of start and finish times. These calculations allow determination of slack times.

True

False

Answer 1

Answer 1 : C. The longest path through the network is the critical path

Explanation : Critical paths are the longest through the network which has no slack while the sequence of activities define the start and end dates of the projects.

Answer 2 : C. Gantt charts are visual tools showing the timing and duration of activities in a project.

Explanation : Gantt charts display tasks against the time while have visual view where the ritical information regarding tasks, duration etc of the project are been displayed.

Answer 3 : True

Explanation : Forward pass is been used to determine project duration, while the backward pass represent end results in which the slack in the activities can be known.
