Sam uses Monte Carlo simulation to quantitatively assess cost and schedule risks of his project...

Some dummy activities in the network logic have an element of uncertainty, which gets bigger over time. While the project proceeds, it is getting even harder to predict how the team members assigned to them will perform.

None of the dummy activities in the network logic has an element of uncertainty, which may get bigger over time.

New risks may have been identified. These influence the input data used for Monte Carlo simulation in a way which was not predictable at the time when the simulation was run.
