• h - A function that takes a value in D and returns a value in E
• i - A function that takes a value in C and returns a value in D
• j - A function that takes a value in B and returns a value in C
• k - A function that takes a value in A and returns a value in B

Returns

A new function that takes a value in A and returns a value in G
