% Base Clauses and Unit Clauses used in proof:
% ============================================
% Base Clauses:
% -------------
% B0: can_be_read
% B1: by_brown
% B2: ~begins_with_dear_sir | ~in_third_person
% B3: ~by_brown | begins_with_dear_sir
% B4: ~can_be_read | ~filed
% B5: crossed | in_black_ink
% B6: ~crossed | on_one_sheet
% B7: ~dated | on_blue_paper
% B8: ~in_black_ink | in_third_person
% B10: ~on_blue_paper | filed
% B11: ~on_one_sheet | dated
% Unit Clauses:
% --------------
% U2: < d1 v0 dv0 f0 c0 t0 td0 > ~filed
% U3: < d1 v0 dv0 f0 c0 t0 td0 > begins_with_dear_sir
% U4: < d1 v0 dv0 f0 c0 t0 td0 > ~in_third_person
% U8: < d2 v0 dv0 f0 c0 t0 td0 > crossed
% U9: < d2 v0 dv0 f0 c0 t0 td0 > dated
% U10: < d2 v0 dv0 f0 c0 t0 td0 > filed
% --------------- Start of Proof ---------------
% Derivation of unit clause U2:
% can_be_read ....... B0
% ~can_be_read | ~filed ....... B4
% ~filed ....... R1 [B0:L0, B4:L0]
% Derivation of unit clause U3:
% by_brown ....... B1
% ~by_brown | begins_with_dear_sir ....... B3
% begins_with_dear_sir ....... R1 [B1:L0, B3:L0]
% Derivation of unit clause U4:
% ~begins_with_dear_sir | ~in_third_person ....... B2
% begins_with_dear_sir ....... U3
% ~in_third_person ....... R1 [B2:L0, U3:L0]
% Derivation of unit clause U8:
% crossed | in_black_ink ....... B5
% ~in_black_ink | in_third_person ....... B8
% crossed | in_third_person ....... R1 [B5:L1, B8:L0]
% ~in_third_person ....... U4
% crossed ....... R2 [R1:L1, U4:L0]
% Derivation of unit clause U9:
% ~crossed | on_one_sheet ....... B6
% ~on_one_sheet | dated ....... B11
% ~crossed | dated ....... R1 [B6:L1, B11:L0]
% crossed ....... U8
% dated ....... R2 [R1:L0, U8:L0]
% Derivation of unit clause U10:
% ~dated | on_blue_paper ....... B7
% ~on_blue_paper | filed ....... B10
% ~dated | filed ....... R1 [B7:L1, B10:L0]
% dated ....... U9
% filed ....... R2 [R1:L0, U9:L0]
% Derivation of the empty clause:
% filed ....... U10
% ~filed ....... U2
% [] ....... R1 [U10:L0, U2:L0]
