Ompare and contrast the realist and the liberalist view of global governance

I am studying Peace and conflict Studies.
Essay topic is (Compare and contrast the realist and the liberalist view of global governance)
it should be written in word program, font size must be 12 and space between each line is 1,5.
1.the essay must have index with page numbers,
It must have 3 parts.
1. introduction part ( one page)
2. Main part ( the discussion part)
3. conclussion part ( half to one page )
and also at end must have bibliography page.
the most important is to also mention the name of write or book inside the text also.
For example: kjdfdkjfkdjfkdjfdA?kfjdkfjkdjfkdjfkjdkfjdkjfkdkjfjdlkfjdljdfjdk ( David. p Barash, P.33)
that was only an example of each page should be dedicated two or three times to a book which is available in norway also.
