- (A) an activity of the project is denoted by an arrow on the net work
- (B) the tail of the arrow indicates the start of the activity
- (C) the head of the arrow indicates the end of,the activity!

Mechanical Engineering Mcqs
- (A) the float may be positive, zero or negative
- (B) if the float is positive and the activity is delayed by a period equal to its total float, the completion of project in not delayed
- (C) if the float of an activity is negative, delay in its performance is bound to delay the completion of project
- (D) if the float of an activity is zero, the activity is critical and any delay in its performance will delay the whole project
- (E) all of the above
- (A) critical path method is an improvement upon bar chart method
