Questions: Liam managed a project to convert an old home into a commercial location to rent as a suite of offices. One of the stakeholders was concerned about the energy efficiency of the old home. Liam met with the window supplier to review the types of windows he had selected to upgrade them to a more efficient line of windows. Which project element was Liam monitoring? Risk Scope Time Cost

The answer is the third one: Time.

Explanation for each option:

1. Risk: This option would involve monitoring potential issues that could impact the project negatively. There is no indication in the question that Liam was focusing on potential risks.

2. Scope: Monitoring scope involves ensuring that the project includes all the work required, and only the work required, to complete the project successfully. The question does not suggest that Liam was concerned with the project's scope.

3. Time: This option involves tracking the project schedule to ensure that tasks are completed on time. Since the question asks which element Liam was monitoring, and without additional context, "Time" is a reasonable assumption as it is a common element to monitor in project management.

4. Cost: Monitoring cost involves tracking the project budget and expenditures. There is no indication in the question that Liam was focused on financial aspects.

In summary, without additional context, "Time" is a logical choice for what Liam was monitoring, as it is a fundamental aspect of project management that often requires close attention.
