AI explanation

Percentage increase is calculated by dividing the absolute increase by the starting population. Statement 2 alone tells us the absolute increase was identical in both decades, meaning the decade with the smaller starting population had the greater percentage increase. This information is sufficient to determine that the first decade had a greater percentage increase, since the first decade precedes the second.
