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 answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

any options?
