C. Improved technology in agriculture means it takes fewer farmers to produce the food the country needs.
Explanation:
The development of farming equipment has caused a reduction in the need for manual labor. Machines such as combine harvesters allow for vast amounts of farm work to completed in a short period. It also helps with extensive commercial farming which means there are bigger farms and fewer farmers.

This question is incomplete, because there is no picture, but I attached one, related with the question. The correct answer Trade winds are shown as number 1.
Explanation:
Trade winds and permamnet winds which blow between Tropic of Cancer, Equator and Tropic of Capricorn (which is between 30 degrees N and 30 degrees S.
These wind always flows from Tropics towards the Eqautor, because around the Eqautor is permanent low pressure area, and around the Tropics is permanent high pressure area. Air always flows from high pressure towards low pressure area.
Due to Earth's rotation trade winds curve a little bit, a they become prevailing Northeasterly Trades (in Northern hemisphere) and Southeasterly Trades (in Southern hemisphere). Earth rotates in west-east direction, and that is the reason for their deflection.
Trade winds got their name in the Age of Discovery (14-15 century) when sailing around the world and explorations were very common. Explorers find out that in specific regions exist winds with permanent direction. That was very importnant in the Middle Ages, so explorers always followed their patterns. Term '<em>trade</em>' is actually from Middle English and it means '<em>track</em>'.
The correct answer is - The population decreases.
A population that doesn't have people moving out of the country, nor people moving inside its borders, as well as high mortality rate, and low birth rate, is a population that will be decreasing rapidly, and that can lead in the end to its total disappearance.
At first the population will start to age, as there will be more middle aged and old people, and much less youngsters. As the time will pass, there will be less and less people for reproduction, and on top of that the ones that do, have one to two children at maximum. The old population will die out, and the numbers will start to significantly drop of the population, as the old and middle aged population are dominating the demographic pyramid.
