Domain: commerce (Product Selection and Specification)
Problem: Please compare two photos of 7-Eleven beverage refrigerators. In the left image (which shows 10 empty slots), I want to fill the empty positions with drinks that appear in the right image (which is almost fully stocked) but are not present in the left image. Each drink occupies one slot, and all drinks are assumed to have the same volume.
My filling method is as follows:
 For the empty spaces in the left image, fill them layer by layer (each layer completely filled before moving to the next), starting from the top layer and proceeding downward (there are 7 layers in total). Within each layer, fill from left to right.
For drinks that exist only in the right image (i.e., not found in the left image), the selection order is:
Lower price first
If prices are the same, choose the one with lower carbohydrate content (per 100 g)
(Prices are based on the labeled retail price.)
Question:
 After the filling process is completed (i.e., the left refrigerator is fully stocked), which beverage is placed in the empty slot immediately to the right of the “Dodo Green Tea (Passion Fruit Flavor)” in the left image?
 Please give the brand name of that beverage.
Answer: Fami Tea Series - Duoduo Green Tea
