Which two regions have the combined highest population density ?
Answer: C
The highest combined population density is for A1, A4.
Combine each pair by adding the animal percentages and dividing by the sum of the forest-land percentages:
\[ \begin{aligned} A1, A4 &: (19 + 11) / (15 + 8) = 30/23 \approx 1.30 \\ A4, A5 &: 25/22 \approx 1.14 \\ A1, A3 &: 39/37 \approx 1.05 \\ A3, A6 &: 35/40 = 0.875 \end{aligned} \]
A4 (Europe) has the highest single density, 11/8, and A1 (Asia) the next, 19/15, so their pair comes out on top. A3 and A6 both have more forest land than animals, which pulls their pairs below 1.
