Question 5 Economists face an obstacle that many other scientists do not face. What is that obstacle? @ It is often difficult to formulate theories in economics, It is often impractical to perform experiments in economics, The scientific method cannot be applied to the study of economics. Economics cannot be addressed objectively; it must be addressed subjectively.12. Refer to the graph above to answer this question. What is the opportunity cost of producing the first 700 quarks? A) It is 6 quirks. B) It is 10 quirks. C) It is 14 quirks. D) The answer cannot be determined from the information given. 13 Refer to the graph above to answer this question.
