To measure the true cost of a pint of B-Positive blood, it is important to consider the various aspects involved. Here is an explanation of each option:

A. None of these: This option suggests that none of the mentioned options would know how to measure the true cost. However, it is possible that other knowledgeable individuals or professionals might possess the necessary expertise.

B. Any competent medical authority: Competent medical authorities, such as doctors, medical researchers, or healthcare economists, might have insights into the components that contribute to the true cost of a pint of B-Positive blood. They could consider factors such as the cost of collecting, testing, storing, and distributing the blood, as well as the expenses associated with staff, equipment, and operations.

C. Only the Surgeon General of the United States: While the Surgeon General holds an important position within the U.S. Department of Health and Human Services, it is unlikely that they alone would have the sole responsibility of measuring the true cost of a pint of B-Positive blood. The Surgeon General might provide guidance or regulations related to the blood donation process, but they may not be specifically tasked with determining the cost.

D. An economist: Economists specialize in analyzing and evaluating financial aspects. They can assess different factors that contribute to the cost, such as supply-chain logistics, market dynamics, and pricing structures. By considering these elements, economists may be able to estimate the true cost.

E. A clerk at the blood bank: While a clerk at the blood bank might have knowledge about the prices charged for a pint of B-Positive blood, they may not possess the necessary expertise to calculate the true cost. The true cost involves a broader understanding of the financial implications and considerations beyond the daily operations of a blood bank.

In conclusion, option B (any competent medical authority) and option D (an economist) are most likely to have the expertise and knowledge to measure the true cost of a pint of B-Positive blood. However, it is essential to consult a range of experts and professionals in the field to obtain a comprehensive understanding of the cost factors involved.
