In this assignment you will apply your economics knowledge to explain and interpret a recently published economics article. You will research and select one article published within the past year that discusses an economics issue from the list provided below and explain the economics of the article. The article may be obtained from a major business or economics journal, magazine or newspaper (The Economist, Wall Street Journal, Businessweek, Times, Fortune, etc.). Using your own words as much as possible, you will explain the main points being made by the article’s author(s), the economic principles used by the author to support his/her argument, and the implications of the story. To do this, you will be applying some of the key economics concepts you have learned in Chapters 1 - 11 of your textbook, to explain the meaning and relevance of the economics story to individuals, firms and/or industry.

""The most crucial detail is that thinking promotes social cohesion and consciousness. people acquire new skills and creative ideas by thinking about solutions to everyday problems. The second important concept emphasized is the power of knowledge. This concept equips people with more details and creativity that exceeds our imagination. Decision making is another crucial aspect that the videos teach. It enables people to choose what is right for them and reject things that may have negative consequences. , people can enhance their knowledge by reading books, watching movies, or listening to people’s narratives. However, they should understand that not all information is helpful. Therefore, they should be able to save the information they obtain from various sources to apply only useful and credible details.""
