The correct answer is - C.) eliminating barriers to trade benefits the economies of member nations.
The regional trade blocs, in fact all trade blocks, are very useful for the economies of the countries that are members in the trade block. The benefit can be seen in the economic sector, as the countries can both, export products on larger markets without tariffs, and import products without imposing tariffs, which benefits the consumers as the prices are lower in that way.
The trade blocks have become a common thing in the world during the 20th century, and that has helped the economies of lot of countries, as well as the choices available and buying power of the consumers.

The specialization of work is as old as the first human groupings, and it was through division by sex. The invention of the wheel dates from at least 2000 years before Christ, and can be extended up to 3,500 years if we take into account the first illustrations of a wheel. The controlled use of fire, in turn, dates back more than a million years, while the development of agriculture is about 10,000 years old. Thus, among the discoveries and inventions pointed out. It is worth noting, however, that the invention of the wheel, while important, would not contribute to such a large population growth.
Agriculture (letter d), gradually improved from 5,000 BC, is the fundamental factor for population growth, which could now settle, rather than live as a nomad.

Answer:
The photosphere, the chromosphere and the ionosphere.
Explanation:
You did not list any layers in your question, however, the sun is composed of mainly 6 layers;
- The core
- The radiative zone
- The convective zone
- The photosphere
- The chromosphere
- The corona
The photosphere is the visible layer of the sun, however, it is very bright even when viewed with a telescope. A filter has to be used to reduce the intensity of the light. This filter is called a myler filter. It is added to the lens of the telescope. Using this, the photosphere can be seen using a telescope.
The chromosphere is an irregular layer above the photosphere. Due to the extremly high temperature, hydrogen emits light which gives off a reddish color. This is known as the H-alpha emmision. Therefore, to see this layer with a telescope, a special filter have to be fitted to the lens of the telescope. This filter is called the hydrogen alpha filter.
The corona is the outermost part of the sun atmosphere, however, it is hidden by the sun's bright surface. It can be seen during a total eclipse. This is when the moon covers the bright photosphere.
Answer:
C
Explanation:
Hierarchy and balance are both principles that are taken into account when making a map. They are important parts of cartography for different reasons.
Hierarchy has to do with combining the many types of features, names, information, and landmarks that are found on the map. A proper hierarchy is necessary so that the elements which need to be visible seem more important.
Balance is an even more visual concept since it deals with the aesthetically pleasing aspect of the map. A well-balanced map will have the map element of the map near the center and will have strategically placed legends and titles that do not take away from the overall depiction of what is being mapped.
