What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: There is at least one x_16 for which if x_16 were an artist, then x_16 is working. For all x_16, if x_16 were a scientist, then x_16 is an artist. For all x_16, x_16 is a scientist or x_16 will make tea. For all x_16, x_16 will work or x_16 will not make tea.
There is at least one x_16 for which if x_16 were a scientist, then x_16 is working can be inferred via the existential transitivity rule. For all x_16, if x_16 makes tea, then x_16 is working can be inferred via the universal rewriting rule.
