Answers

Answer:

China, Ireland; Germany, Vietnam

Explanation:

A multi-state nation occurs when a nation stretched across international borders, therefore across states

China - currently a mutli-state nation:

The Nationalist party in China fought against communist forces before and after WWII but by 1949 the Communist under Mao Zedong won. The Nationalists then fled to Taiwan and claimed they were the legitimate government of China. Today, 95% of people who lin in Taiwan are Han Chinese. Therefore, the people or nation (the Chinese) are split between China and Taiwan.

Ireland - currently a mutli-state nation:

The Irish War of Indepence took place from 1919 to 1921 and resulted in Ireland’s independence from the U.K along with Ireland becoming split. In 1921 Northern Ireland was created when Ireland was partitioned by the Government of Ireland act of 1920. The majority of Northern Ireland’s population were unionists who wanted to remain with the U.K. and this act created a devolved government for the 6 northeastern counties. Today, the Irish people are divided between the Republic of Ireland and Northern Ireland which is still part of the U.K.

Germany - was a mutli-state nation in the past:

After WWII the eastern part of Germany including the 5 landers of Brandenburg, Mecklenburg-Vorpommern, Saxony, Saxony-Anhalt, and Thuringia was occupied by Soviet forces. In 1949, Germany formally split into 2 independent states: The Federal Republic of Germany (West Germany - democracy) and The German Democratic Republic (East Germany - communist). In 1961 the GDR/East Germany built the Berlin wall overnight on August 13, creating a physical border between East and West Germany. In 1989 communism fell in East Germany and the Berlin Wall was torn down the same year. The country was reunified in 1990.

OD. Fewer workers receive the education needed to create the product.
SUBMIT

Answers

Answer:

B: New technology allows the product to be made quicker

If a product can be made quicker, you can make more products in less time, resulting in more supply/stock.

New technology allows the product to be made more quickly. The correct option is B.

What is technology?

The tools, methods, and systems used to create, process, store, and exchange information, or to perform tasks that make life easier and more efficient, are referred to as technology.

Because it improves the efficiency of the manufacturing process, the development of new technology that allows a product to be manufactured more quickly can increase the supply of that product.

Lowering production costs can make it more profitable for producers to supply more product to the market.

As a result, they may increase production to meet rising demand or to take advantage of lower production costs, resulting in an increase in product supply.

Thus, the correct option is B.
