relational schema and functional dependencies:

Having trouble doing this homework question, its supposed to be simple.

 

Answer these questions given the following relational schema and functional dependencies:

R(A, B, C, D, E, F, G, H, I, J)

B -> E  ;  E -> F,H  ;  B,C,D -> G  ;  C,D -> A  ;  A -> J
I -> B,C,D,E ; H -> I
  1. List all candidate keys of R. 
  2. Does the functional dependency B -> J hold? 
  3. Does the functional dependency C -> A hold?
  4. Normalize R into BCNF. Make sure to underline primary key fields. 

I've attached a example
