The document contains 6 sections (A-F) providing truth tables and expressions for logical expressions X in terms of variables A, B, C, and D. Section A gives the truth table and expression X = A(B+C) + BC. Section B gives the truth table and expression X = AB + AC = A(B+C). Section C gives the truth table and expression X = AB(C+D) + CD(A+B) + ABCD + ABCD. Section D gives the truth table and expression X = ABCD + AB(C+D) + BCD + ACD. Section E gives the truth table and expression X = C + BC. Section F gives
