A country imports goods and services worth $700 million and exports goods
and services worth about $500 million. This means that the country has an)
a. trade surplus
b. trade deficit
c. comparative advantage
d. absolute advantage

Answers

Answer:

B. trade deficit

Explanation:

just did it on a-p-e-x

A trade deficit occurs when a country imports more goods and services than it exports. In this case, the country is importing goods and services worth $700 million and exporting goods and services worth about $500 million, indicating a trade deficit of $200 million. The correct option is b.

What happens with a trade deficit?

The salaries of domestic workers are lowered when there is a trade deficit, placing many of them in lower-income tiers. Saving money is typically far more difficult for low-income families. Decreases in national savings can and do result from growing trade imbalances.

A trade surplus, on the other hand, occurs when a country exports more goods and services than it imports.

Comparative advantage and absolute advantage refer to a country's ability to produce a particular good or service more efficiently than other countries. They are not directly related to trading deficits or surpluses.

Thus, the ideal selection is option b.

What does Feldman explain as being the three extraordinary components of the Constitution?​

Answers

Answer:

The three parts of the Constitution are the preamble, the seven articles, and the amendments. The preamble sets forth the purpose of the Constitution. The articles define the country's governing structures. The amendments present the Bill of Rights and deal with voting rights, presidential succession, terms of office, and other issues.

Explanation:

One is freedom of speech. This was an innovative idea at the time. Namely, that if you were out of power, you could still say that the government was terrible.Two civil society organizations. The capacity to put together private groups, individuals, political parties, and others who would organize to try to bring about fundamental change. Perhaps most significant was the separation of powers. the president needs people, elected officials who know they need to win elections from centrist voters and also to back his or her policies in order to pass laws. Without it, nothing much happens.

Should a Female with the same Qualifications as a Man, if selected for an Executive Position formerly held by a man, be paid the same salary as her counterpart prior to her?

Answers

Answer:

The simple answer is yes a female should be paid the same, but often this is not the case.

Explanation:

Morally, yes a female with the same qualifications and experience should be paid the same salary as the counterpart prior to her, though it is not a law that there can't be a wage gap between women and men and this is most commonly not a reality. Women are often paid less than men with the same degree, qualifications, and experience, especially if the woman is part of a racial minority, or in a male dominated industry. Often, employers are able to find loopholes and reasons, "justifying" this unjust wage gap.
