Answer: Outer core
Reason: As Earth spins on its axis, the iron inside the liquid outer core moves around. The movement causes powerful electric currents to develop in the liquid iron itself.
Originally, colonialism had caused a great divide between the the colonial slaves and Spanish and Portuguese people. However, owing ti the contact between slaves and owners in these colonoes, the concept of equality between races became easier to grasp for the South Americans. They started viewing the race barriers more open-mindedly. Moreover, cross-mixing caused numerous social classes to be created of mixed race.
The correct answer is - I, II, and III.
By the obscure information about the Region A and the size of the farmlands in it, we can roughly conclude that the Region A has a topography which is not allowing for larger farms to be formed, the people in that region are probably not financially very powerful, and that the farming is not heavily mechanized.
Very often the topography of a region can dictate the size of the farmlands, as there's only certain places that are suitable for farming. So if the region is mostly hilly and has mountains, the farmlands can be very big.
Another factor that can be crucial in determining the size of the farmlands is the financial power of the people. If the people can not afford to buy bigger land areas, than the farmlands will be relatively small.
If the farmlands are not big, than they can be worked with less mechanization, with the human and animal power being in the spotlight, but also, if the farmers are not financially strong enough, they will not be able to buy the needed mechanization.
<span>It reduced coast-to-coast communication from about 180 days to about a week.
This question is mildly ambiguous due to the word "communication". Does it mean "Speed of sending a message?" or "Speed of moving a physical object?" Given the available options as answers, I will assume the meaning is "Speed of moving a physical object?" With that in mind, let's look at the available options and see what makes sense.
It made coast-to-coast communication instantaneous.
* Even modern jets can't travel from coast to coast instantaneously, so you wouldn't expect a train to do so either. So this choice is just plain silly and therefore wrong.
It reduced coast-to-coast communication from about a week to about a day.
* A stagecoach had an average speed of about 5 mph and covered 60 to 70 miles per day. So it's not going to go from coast to coast in only a week. And since that part of the answer is wrong, this choice is wrong.
It reduced coast-to-coast communication from about 180 days to about a week.
* The 180 day estimate is definitely doable. That's an average speed of about 17 miles per day which is a good speed for a person walking day to day. And that would be about 400 miles per day for the train. The numbers make sense and this is the correct answer.
It made coast-to-coast communication more complicated.
* Let's see. Buy a train ticket and possibly arrange for 6 layovers. Or plan a multiple month trip and possibly coordinate that effort without having any rapid means of communications? This option is just plain silly when you consider the logistics of traveling for several months vs traveling for a mere week. So this is a bad choice.</span>
If i remember correctly its B im not sure
