Actually, the answer is A. I just took this test and got it right.
The correct answer is - Greenhouse effect.
The Greenhouse effect is a process in which certain type of gasses in the lower atmosphere manage to trap the heat that is radiated from the surface of the planet.
The gases that are considered to be greenhouse gases are able to perform such a thing, despite being relatively low in amount compared to other gases, because they have much more complex molecular structure.
The molecular structure of this gases enables them to trap the heat, or rather to not allow to leave the atmosphere and return it back toward the surface, thus having huge effect on the climate.
Greenhouse gases are the carbon dioxide, methane, water vapor, nitrous oxide.
In order for an economist to compare the living standard in two different countries, he/she will need to take multiple parameters in consideration and compare all of them individually, after them sum them up and make the final conclusion.
One of the things is the GDP nominal of the countries, which shows how strong the economy of the country is, and in which direction it is moving. Then the GDP per capita, which will reflect how much actually the citizens earn on average. The prices of the goods and services in the countries come as next, and their prices are then compared with how much the GDP per capita, so that the economist can see what is the economic power of the citizens. The availability and quality of the institutions of the countries, the infrastructure, corruption rate, freedom of speech, will all be examined in order to determine the living conditions that are available to the people. So once all of these things are examined and summed up, the economist will be able to make a proper comparison of the standard of living in the two countries.
