Was containment an effective policy to thwart (stop) communist expansion?​

Answers

The effectiveness of containment as a policy to thwart communist expansion is a subject of debate among historians and political analysts.

Containment was a strategy developed by the United States during the Cold War to prevent the spread of communism, particularly in Europe and Asia.Proponents of containment argue that it was largely successful in limiting the territorial expansion of communism. By providing military and economic aid to countries threatened by communist influence, such as Greece and Turkey, and engaging in alliances like NATO, containment helped prevent the direct takeover of countries by communist forces.Critics of containment argue that it had mixed results. They point to instances where communism was not contained, such as the spread of communist regimes in Vietnam, Laos, and Cambodia. Critics also argue that containment fueled proxy wars and conflicts, leading to human suffering and instability in various regions.While containment had some successes in preventing direct communist expansion, its effectiveness varied depending on the specific context and region. The ongoing debate underscores the complexities and challenges associated with implementing strategies to thwart ideological movements.

The Tang Dynasty of China was notable for returning civil-service exams to use and creating the following type of society based on ability rather than birthrights:

The type of society it created was a society based on merit. Yes, a society based on personal merit, knowledge, and progress, instead of birthrights.In Imperial China times, Civil Service Examinations were a requirement to choose the appropriate candidate to occupy an office in the government.

During the Teng Dynasty, the government changed its military approach to a more type of bureaucratic system.This new system was run by Chinese civilians that had the knowledge and credentials to occupy these positions.

We conclude that one consequence of the civil service examination system used by the Tang dynasty was that Chinese government officials were selected based on their skills and abilities rather than their family history.

Jinny is selling bracelets for $4.50. So far, she has earned $315.00. She needs to earn more than $459.00 in order to meet her goal. How many more bracelets, x, does she need to sell in order to reach her goal? Select the inequality that includes the fewest number of bracelets that she can sell and still reach her goal. A. x > 70 B. x > 32 C. x > 172 D. x > 102

Answers

Answer: The answer would be D which is 102

Explanation:

Well, if you divide $315.00 by $4.50 you get 70. That would be correct if she needed to earn exactly $315.00 but she needs to reach her goal of $459.00. So $459.00 divided by $4.50 is equal to 102. 102 is the fewest number of bracelets she can sell and still reach her goal.
