The question states " The project schedule in the diagram above has 12 activities needed for the project’s completion. These activities are labeled A-L.
How many activities must be completed before activity G can start?"
The answer is “The answer is 4. This is an example of a network diagram. In a network diagram, activities exist in a sequence which determines when the activities can be completed based on the other activities in the project. All activities connected by a line must be completed before other activities can start. In this example, Activities A, B, C, and D must all be completed before activity G starts.”
I’m confused as to why it isn’t 2, seeing as it is a clear path to G and both require 2 activities to reach G. I also tried to look up Network Diagram in the AHPP and could not locate it. I just don’t understand the logic behind this diagram. What is the point of it?
