why do people who live on islands tend to develop very different customs from those who live in other parts of the world

Answer :

1) They're isolated from the other cultures so they don't have cultural contact with theim

2) their situation is special in that they have a lot of access to the sea (sea food) but with not as mush arable land available (they are restricted to the size of the island) - this influences their customs (less harvest related, more fishing related)

Answer: I know you don't want to read the one above so your answer is A
