What if the United States, Mexico, and Canada took the EU's example and joined to form a North American Union? Based on your knowledge of the European Union, describe two setbacks or hurdles that this idea might face.

If a North American Union was created, the biggest problems that would occur would be rapid population shifts, and lower wages because of much-increased competition on the labor market.

Explanation:

A North American Union, by EU's example, would mean that the US, Canada, and Mexico will function as one in many ways. The borders will be open, both for economic actions and for free movement of people. While this may seem good at first sight, it will actually cause some major problems as well.

The US and Canada will face a major population increase in a very short period of time. The people from Mexico will rush to move into these two countries because of better living conditions and more job opportunities, which in turn will cause massive depopulation in Mexico.

On one side, Mexico will face major economic problems because of a sharp decline in its labor force, while on another side, the people in the US and Canada will face problems because there will be tens of millions of new laborers that will offer their services for lower wages. This will lead to tens of millions of people losing their jobs or not being able to find jobs, or if they do, they will have to work for less, meaning that they will be poorer.

answer; i believe that the correct answer is (the explosion of a nearby star(supernova);

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
