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: For all x_8, x_8 will not go running or x_8 will write a letter. Linda is not writing a letter or it is sunny. For all x_8, x_8 will go running or x_8 is a cashier. Linda is not a cashier or Elisabeth is drinking water.
For all x_8, x_8 is a cashier or x_8 will write a letter can be inferred via the universal resolution rule.
