Consider the following premises. forall x_15: R_15(x_15) -> R_2(x_15). forall x_15: P_15(x_15) or W(x_15). forall x_15: ~P_15(x_15) or R_15(x_15). forall x_15: P_13(x_15) <-> W(x_15). exists x_15: R_6(x_15) -> R_2(x_15). forall x_15: P_13(x_15) -> R_6(x_15). Can we infer forall x_15: R_15(x_15) -> R_2(x_15) from them?
That is one of the premises. Therefore, the answer is yes.
