Answer:
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. The Green Revolution in the mid-1900s saw the development of high yield variety crops that were stronger and more reliable. While more fertilizer and water is needed, people are not.
Planet A is an outer planet, and Planet B is an inner planet, then Planet A will spin (rotate on its axis) faster than Planet B.
Using our Solar System as a model, we may determine the following:
The inner planets, which include our Earth, Mercury, Venus, and Mars, revolve more slowly than the outer planets (such as Jupiter, Saturn, Uranus and Neptune). The reason for this is because the nearest planets are held firmly in place as they revolve around the Sun due to the massive gravitational field of the star.
However, for the same reason (because of their proximity to the Sun's gravitational field), inner planets complete one circle around the Sun faster than outer planets.
As a result, Planet A will spin (rotation on its axis) faster than Planet B if Planet A is an outer planet and Planet B is an inner planet.
