Answer: The charts above help show that the wealthier countries (France, Italy, and Poland) have more developed economies, which is why agriculture isn't as big a part of the economy as it is in Romania, for example. Because the economies of the first 3 countries are developed, they can be considered Stage 4 countries, or countries that have developed economies and stable populations. Romania, on the other hand, still depends on agriculture for almost 1/3 of its total economic output, and could therefore be classified as a stage 3 country (a country with a developing economy and a stabling population). In summary, France, Italy, and Poland have a more developed economy than Romania, and this shows by what economic activities go on in each country to make up for the data shown.
I hope this helps!
