TM1 Puzzles and Diversions. Consolidated Feeders

I’m running our interpactice (we’ve got Singpapore and Sydney offices) TM1 sessions. Currently playing with the “quick / easy / conceptual puzzles” approach. Beats my lecturing so far -)
I’ll publish some old ones in this blog, post the answers in comments or in an email on mail@ykud.com. If you can answer the question #2 for this one correctly and explain it — beer/wine is on me, I failed it.

TM1 model is the set up as the screenshot below.
