Suppose the real risk-free rate is 4.20%, the average expected future inflation rate is 2.50%, and a maturity risk premium of 0.10% per year to maturity applies, i. e., mrp = 0.10%(t), where t is the number of years to maturity, hence the pure expectations theory is not valid. what rate of return would you expect on a 4-year treasury security? disregard cross-product terms, i. e., if averaging is required, use the arithmetic average.

the correct answer option is b. a single paragraph.

explanation:

when you are thinking about paragraph​ topics, you should always choose a subject that can be adequately addressed in a single paragraph.

a paragraph is a piece of writing consisting of a few sentences that deal with a single theme. it has only a single idea that the paragraph revolves around and talks about.

so a paragraph topic must be chosen wisely where a single idea can be communicated in a single paragraph.

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
