\begin{tabular}{l}\hline 6) Jill runs a factory that makes lie detectors in Little Rock, Arkansas. \\ This month, Jills 34 workers produced 680 machines. Jills average \\ product of labor equaled __ lie detectors per worker. \\ \hline OA) 680 \\ \hline OB) 34 \\ OC) 23 \\ OD) 20\end{tabular}

To find Jill's average product of labor, you divide the total number of machines produced by the number of workers. In this case, she produced 680 lie detectors with 34 workers, so you calculate: Average Product of Labor = Total Production / Number of Workers = 680 / 34 = 20 lie detectors per worker. So, the answer is OD) 20. Now, on to some fun facts about lie detectors and their historical context! The polygraph, often colloquially called a lie detector, traces its roots back to the early 20th century when John Augustus Larson, a medical student, created the first prototype in 1921 for the Berkeley Police Department. Since then, it has sparked fascination and controversy alike, raising questions about its reliability and ethical implications! For those interested in the practical applications of lie detectors, they’re widely used in criminal investigations and pre-employment screenings. However, exploring their efficacy can be a rabbit hole, with studies showing they work mostly on the principle of physiological response rather than actual honesty, leading to debates about their reliability and legitimacy in various fields!
