Explanation: An event is represented by a circle and a node is a synonym for an event. An activity starts and ends with an event and is represented by an arrow. A dummy activity may be critical or non-critical. A dummy activity is critical when its earliest start time (EST) and latest finish time (LFT) are the same.

Correct Answer: C. C. Both the milestone chart and bar chart
Explanation: Milestone chart and bar chart were used for the development network techniques. These charts have many limitations which made them inefficient for planning large and complex projects.

Correct Answer: InvAlid answer

Correct Answer: C. C. Graphical evaluation and review technique
Explanation: G.E.R.T. is the acronym for ‘Graphical Evaluation and Review Technique’. It is also one of the network techniques of network analysis.

Correct Answer: C. C. It is a dotted line connecting the two head events and consumes no time
Explanation: A dummy activity is a dotted line connecting the two head events and consumes no time. A specific instant of time which marks the start and the end of an activity is called an event. An activity is an element of the project and has a specific time duration. A critical activity consumes more time than the estimated time, thereby delaying the entire project duration.
