At an event other than the final event, if no activity emerges, it results in an error called
- ALooping
- BDanglingCorrect
- CInterfacing
- DSplicing
Solution
Concept
Dangling error in project network diagrams
Formula
NONE
Step-by-step solution
1. Network logic requires every intermediate event to have incoming and outgoing activity paths. 2. An event without outgoing activities prior to the final event creates an error in logic. Answer: B
Explanation
In network analysis, a dangling error occurs when an intermediate event is created without any outgoing activities, effectively leaving a dead end in the network logic. Every intermediate event must connect to subsequent activities leading ultimately to project completion. Therefore, option B correctly names this network error.
Why the other options are wrong
A) Looping refers to a cyclic path error in a network diagram. D) Splicing is not a standard term for a network diagram error.
Shortcut
An unconnected intermediate node with no outgoing activity is a Dangling error.
Common mistake
Confusing dangling with looping, which involves endless cyclical activity loops rather than unconnected event nodes.
Correct answer: B) Dangling
