Part A) Consider the relation schema R(A, B, C, D, E, F, G, H) with the FDs S = {A B, ABCD E, EF GH, ACDF EG}. Compute a minimum cover S_c of S and explain the steps in detail.

Part B) Given R and F from the previous question as well as the attribute sets AB, ACDE, ACDF, and CDG, list all attribute sets that are superkeys of R.
