Solution

1) * to * because one movie can many actors and one actor can have many womans.

2) Create a class sequel and make an association with Movie.

3) 1 to 1..* because the original movie could be just one and it can 1 or more sequels.

4) A label \'isSequelOf\' placed in middle of an association line.
