The correct answer is D) these countries have transitioned to democracy, and the US has decreased aid to them.
The statement that best summarizes how US national security policy has changed in Latin American countries such as El Salvador, Chile, and Nicaragua is " these countries have transitioned to democracy, and the US has decreased aid to them."
With so many problems in their daily lives, these South American and Central American countries are democratic ones than had been receiving less help from the United States. However, democracy for them does not mean that things are doing right in their respective countries. The economy is a big problem in Central American. People from Nicaragua, El Salvador, and Honduras are trying to migrate to the US in thousands, strained in the US-Mexican border.
Right now, people in Chile are taking the streets to protests about economic injustices and poverty that affect their country.
The other options of the question were A) these countries have transitioned to military rule, and the US has increased aid to them. B) these countries have experienced recent Communist revolutions and the US has cut off aid to them. C) these countries have transitioned to democracy and the US has increased aid to them.
<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>
