The image shows a map of the Americas, in which countries are classified by colors according to the cubic meters of gas they produce per year; the countries that produce more than one hundred billion cubic meters are in brown; those that produce more than ten billion cubic meters are in red; those that produce more than one billion cubic meters are in orange; those that produce more than one million cubic meters are in yellow and those that produce less are in blue.

According to this, it can be concluded "The regions of North America have similar levels of gas production" because the area of North America icluding Mexico, United States, and Canada are important gas producers; indeed these countries produce at least ten billion cubic meters of gas per year, and therefore these countries have a similar although not identical production rate. So, the correct answer is D. The regions of North America have similar levels of gas production
