This is a game simulation. The goal is to find which deer will be infected after time 3 based on deer weight, deer age, humidity, temperature (4 different combinations).

Each deer is a circle (with age & weight) on the map. All the pictures are currently taken at time 2. The white boundary specifies the area that virus can be spread to. The deers with black dot on it are the infected deer at the current time (time 2). The deers with the purple dot on it are the deers that will be infected in the next time (time 3).

What do you think is the procedure to solve this part ?
