Theorists using a "functionalist" perspective emphasize that families are important for society because they are the primary source for the procreation and socialization of children.
<u>Explanation:</u>
The functionalist viewpoint sees society as a complicated system, the parts of which work together to foster unity and stability. This viewpoint looks at society through some kind of macro-level prism, and usually emphasizes on the social structures that make up society as a whole. 
The government, for instance, offers education for the family's children, which in effect pays taxes on which the state relies to continually run itself. From this viewpoint, system disorganization, like immoral behavior, leads to transition because it demands that social structures adapt to maintain equilibrium.

Answer:
Variable interval
Explanation:
In a variable interval, the researcher will not give the reinforcement on a regular schedule. 
The purpose of this type of reinforcement is to condition the subjects to adopt a certain behavior even after the reinforcement is taken away in the future.
<u>Example:</u>
Let's say you want to teach your son to put away his toy after he's done playing it. 
In order to encourage him, you give him his favorite candy as soon as he's putting away his toy, but you do not give the candy every time he does it. Sometimes you give it, sometimes you don't.
When this happen, your son will start to develop an understanding that there is always a possibility for candy every time he put away his toy.
This will make him more likely to put the toy away and wouldn't sulk even after he does not receive the candy.
