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_6 for which if x_6 were bored, then x_6 is running. For all x_6, if x_6 reads a book, then x_6 is bored. For all x_6, x_6 will read a book or x_6 is not a scientist.
There is at least one x_6 for which if x_6 reads a book, then x_6 is running can be inferred via the existential transitivity rule. For all x_6, if x_6 were a scientist, then x_6 is reading a book can be inferred via the universal rewriting rule.
