<span>The world controller orders the hatchery to create embryos with different intelligence levels to fit into different sections of society. Alphas require a lot of intelligence to perform complex activities like Bernard's job of overseeing the night-time conditioning of the young. By comparison, the lowest cast, Epsilons, are deprived of oxygen during embryonic formation and given alcohol to ensure they will have very little intelligence and thus be fit for the lowest jobs in society.</span>
Answer: correlation vs. causation
Explanation:
Correlation assesses the relationship between variables and can be in the same direction, where the increase in one exists as the same time as an increase in the other variable or inverse where an increase in one variable occurs when there is a decrease in the second variable. However, this correlation does not indicate causation.
Causation signifies that one variable is responsible for the occurrence of an event in the other variable. Clearly, there is no cause and effect between the number of mules and doctorate degrees in a state. Here, there is a correlation but a fundamental causative factor is absent between the two events.
An example that shows how Romans gave away citizenship rights in measured amounts can be seen when we look at the difference between the <em>Latini</em> and the <em>Foederati</em>.
The <em>Latini</em> were people who were born outside of Rome but on the Italian peninsula. Their citizenship allowed them to do business with Rome, and travel and live within the Empire. However, they were not allowed to have a Roman marriage. The <em>Foederati</em>, on the other hand, were the citizens of states that had obligations towards Rome. They were given limited citizenship rights in exchange for military service.
