Answer:a. shows low resistance to extinction; shows high resistance to extinction

Explanation:

According to psychology, extinction occurs when a conditioned response is slowly eliminated or weakned which over time will result to that behavior being extinct. This means a conditioned behavior is completely eliminated

An example is when you whistle to a dog all the time to come and get food and the dog starts to drool all time at the thought of whistling associated with food , if you gradually start to whistle without carrying the food with you the dog will stop salivating or drooling.

In classical conditioning, when a conditioned stimulus is provided without an unconditioned stimulus the conditioned response eventually get extinct.

Jeremy is not resistant towards getting rid of the gambling behaviour because when he start gambling and is no longer getting paid off he immediately stops so when an unconditioned stimulus is taken away , he stops gambling and if this keeps happening gradually his behavior of gambling will be extinct.

Jessica on the other side continues even when the unconditioned stimulus (being paid off )is taken away she still continues to gamble so she is resistance towards stoping her gambling behavior.

nataly862011 [7]

Distributive conflict consists, literally, in the dispute over the distribution of wealth (income) among social classes. For example, workers are a class that reinvigorates higher wages (greater share in distribution) while entrepreneurs aim to lower wages to increase their own share of total income distribution.

Distributive conflict occurs in all areas of the economy, whether in the productive or financial sphere, and the rationale for the analysis lies precisely in the demonstration of classses as economic classes.
