Thanks for participating in the challenge. It will remain open until next month’s challenge. It might be tricky because no one has selected the ‘Tracked entities’ layer (correct) but some have missed a layer. You’re welcome to double check the answer! 
** Update:
Hi there!
Congratulations for receiving the CoP Activity Winner badge, and if you’re wondering what’s the correct answer: Thematic, Boundaries, and Facilies layers are used to analyze aggregate data; however, Tracked Entities and Population layers are specifically to analyze Tracker data.
