Kevin is intrinsically motivated.
This means that he is motivated to do something purely because he is interested in it and actually enjoys it - he likes math even though he never studied it officially, which is why he spends almost every night studying. If he studied math for a job, then it would be extrinsic motivation.

A presentation is called multimedia if it uses more than one kind of medium. A multimedia is a combination of two or more types of media combined together as a single package. It is usually composed of a video, sound, animation, text and pictures.
Societies are naturally diverse and its easy to see why it is.
Interests: Some people prefer to stay inside and use a lot of electronic devices. While others prefer nature and the outdoors, so they go hiking an camping.
Beliefs: This is an easy example, the united states has many churches with many religions, so the belief systems are different.
Age: Even in your house, age diversity is present! You might be 15 while your parents are 35, and your grand parents are 73! This a common form of age diversity.
Hope I helped. :)
