Answer:
Primary
Explanation:
In psychology and operant conditioning, the term Primary reinforcer refers to the biological reinforcers that determine our behavior. In other words, they are part of our nature and reinforce behaviors in a natural way without a process of learning from us, since they are, by themselves, satisfying a biological need. Therefore, they have innate reinforcing qualities. Examples of these reinforcers would be: food, sex, water, sleep.
Therefore, in operant conditioning, a primary reinforcer is innately reinforcing, often by satisfying a biological need.
The correct answer is B. Buying a good in one market and selling it in another for a profit.
Explanation:
The term "arbitrage" is used in the economy and similar contexts to describe the process in which a person, company or similar profits due to the differences in prices in different markets. This commonly implies an asset, product or service is bought in one market at a low price and then this is sold into a different market at a higher price which implies profit for the entity or individual that buys and sells the good. For example, a company or individual can buy a certain product in a foreign market where is cheaper due to the price of the foreign currency or changes in prices and then sell this at the local level. Therefore, arbitrage refers to buying a good in one market and selling it in another for a profit.
