In 2012, Lance Armstrong was stripped of his record-setting, seven Tour de France titles and banned for life from competitive cycling because of his alleged use of performance-enhancing drugs (PEDs). One of the PEDs Armstrong was accused of taking is erythropoietin (EPO). Why would systematic use of this PED give Armstrong an unfair advantage in a bike race?
A. EPO stimulates the synthesis of myoglobin by muscle cells. B. EPO stimulates the formation of new alveoli in the lungs. C. EPO stimulates formation of new capillary beds in skeletal and heart muscle. D. EPO increases cardiac output by stimulating the ventricles to contract more strongly. E. EPO stimulates red blood cell production by the bone marrow. F. EPO stimulates growth of cardiac and skeletal muscle tissue. Clarify Question What is the key concept addressed by the question? What type of thinking is required? Gather Content What do you already know about erythropoietin? What other information is related to the question? Choose Answer Given what you now know, what information is most likely to produce the correct answer? Reflect on Process Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
