71% of Earths surface is covered by water.
A) Ha crecido rápidamente en los último siglo.
The answer is C because, without any of the three options the message behind the speech will easily be ignored. The reaction the speaker wishes to invoke will go unnoticed if their appearance doesn't match their sophistication. The speech will be considered a simple letter or message if there isn't any emotion nor encouraging words. The audience will no longer contribute or care for the speech with the lack of these options, all are required.
Answer:
There are greater opportunities for trade in the pacific rim than in the steppes.
Explanation:
Trade is something that has been used by humankind for thousands of years. The reason is simple - it is the basis of any economic type, be it primitive, command, market, etc... Basically, through trade, the individuals, groups, countries, regions, get the goods they need in exchange for the goods they have to offer and are needed on the other side.
Not all places on Earth provide the same opportunities for trade though, and in most cases the reason for it is geography. The Pacific Rim, for example, is a huge region and there are countries on all levels of development. It is a region where infrastructure doesn't have much influence because trade goes through water, and even though it is a huge distance in question from one side to another, trade is very easy. On the other hand, we have the steppes. These areas are sparsely populated, are usually low on resources, the climate is harsh, which in turn makes the countries dominated by them are less developed, and that in turn means infrastructure in bad condition or fully lacking in most of the territory. Such conditions result in bad conditions for trade as the opportunities are much lower than in other regions.
