Hi Damianos

​Thank you for your query.

When comparing two simulation results in the Visual Business Director, "Reference" is typically the "baseline" - a simulation that you have run earlier and "Source" is typically the current simulation in question.

Assuming this is the case (and that is also the general assumption as explained in the lesson), a red indicates that there is a drop in KPI in the latest (or "Source") simulation when compared to the "Reference" (or "baseline").

So, the correct answer is "The value of the KPI in the reference simulation is smaller than the value in source".

Hope this clarifies.

Feel free to write back for more clarification.

I fully agree with you, this is the answer I gave, but the system marked it as incorrect!

I guess someone from Pega Academy needs to fix this problem, as it can be very confusing.
