Explanation:

1. First, find the obesity percentage in 1980 (from the graph, it's 13%) and in 2010 (36%).
2. Calculate the ratio of 2010 percentage to 1980 percentage: $\frac{36}{13}\approx2.77$, which is close to 3 (tripled).
3. Check other options: Doubled would be ~26, quadrupled ~52, and "remained same" is incorrect. So "Obesity has almost tripled" is correct.

Answer:

Obesity has almost tripled.
