Through the executive order 9066, Roosevelt give authorization to government officials to relocating  of tens of thousands of American citizens with Japanese ancestry.

Which among the following countries does not have a railway?​
Iteru [2.4K]

Answer:

There are several countries without trains or railways. Most are either small countries on islands (Iceland for example, has none) or poor countries that really can't afford the cost of maintaining them. HOWEVER most of these countries HAVE HAD railways of some kind at one time or another (Guyana, for example has pretty much nothing but was in fact the first country in South America to have railways at all. Iceland also has had a few small railways built temporarily in the past for construction purposes).

As an aside, it is not always necessarily the countries fault that they have no railways. Many are former colonies of European countries that all had outside influence on the railway construction. Sometimes, if more than one power had a grip on an area, railways of completely different gauges (sizes) would be built by the opposing powers.

Also, the countries obviously only cared about the railways (and the colonies themselves) as a means to make THEM stronger, so the railway systems usually only consisted of a line going straight from whatever rare mineral or something that they wanted to the nearest port, for shipment back to the main country.

Not only were these impractical for serving the entire nation, they were (and still kinda are) a symbol of their former tyrants to the locals. So when the little countries finally broke away from their oppressors they often wanted little to do with railways or trains.

As far as lists of all the countries that don't have them, they aren't really complete, although train buffs like these guys will throw out some names and see if they've got trains or not.

Which statement BEST explains how specialization encourages trade between countries?
Maru [420]

Answer:

2. The US imports oil from the Middle East while some countries there rely on the US for food and technology.

Explanation:

A specialization occurred when the process of production a certain product become so cheap and efficient in a country. This allow them to focus their time and resources solely on producing that product and imported other product that they need.

The middle east had the largest oil reserves in the world (As per today, it's 10 times more than US have. They might have some that they haven't discovered yet) .  For United States, this means that importing oil from the middle east is much cheaper compared to producing it by their own. They could focus that time and resources for producing foods and technology instead.
