Consider the following premises. Robert is curious. For all x_7, x_7 will not drink water or x_7 will work. For all x_7, x_7 is not curious or x_7 is rich. Can we infer the following from them? If we can, name the inference rule being used: For all x_7, neither x_7 is rich nor x_7 will work.
That contradicts the premises. Therefore the answer is no.
