Answer:
B - need to belong theory.
Explanation:
As the exercise briefly describes, the theory that says that each of us is born with a fundamental drive to seek, form, maintain, and protect strong social relationships is called need to belong theory. This refers to the idea that we, as humans, have the fundamental motivation to be accepted into social groups, stating that belongingness is a need.
The answer to this question is <span> fixed ratio
In a </span> fixed ratio schedule of reinforcement, it requires <span>subjects to provides a set number of responses and a reward will be given after the completion of a certain numbers. Because of the high certainty, we will tend to receive high and steady rate of response if we use this type of schedule.</span>
This is the kind of concept a utilitarian would agree on. If the result is positive for a large group of people, we should seriously consider doing it.
However, I would like to comment on this concept. In my opinion (and that's what you're asking for) there are situations in which the ends don't justify the means. You can e.g. think about mass-bombings to fight against terrorism. However, the possibility exists that innocent people will be hit, and will die. Therefore, the end don't always justify the means (in my opinion).
