Answer:
I belive that its C but if that is wrong then its B
Explanation:
The compressor, condenser, expansion valve/throttle valve, and evaporator are the four elements that make up the vapor compression cycle.
The main difficulties in vapor compression refrigeration system miniaturization for designs based on standard-scale systems have to do with component integration and miniaturization.
The most important aspect of all mechanical refrigeration systems is the creation of a compact yet effective gas compressor.
The first factor is connected to the most basic separation mechanism that comes to mind: gravity. The maximum vapor velocity that is permitted should be determined by looking at the terminal velocity of the droplets if gravity settling is to be employed as a separation technique. This will prevent the droplets from being swept away with the vapor.

The answer is: D. An increase in literacy rates can lead to a higher standard of living
Literacy rates affect how well people would be able to learn new and a more advanced skills. This mean that higher literacy rates would give the countries in latin america more high-skilled labours.
The more high-skilled labours that a country have, the more efficient the production that they can do, leading up to an increase in GDP and higher standard of living for people in that area.
