What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_7, x_7 is excited or x_7 will not write a letter. There is at least one x_7 for which x_7 will write a letter or x_7 is not excited.
For all x_7, if x_7 writes a letter, then x_7 is excited. There is at least one x_7 for which if x_7 were excited, then x_7 is writing a letter.
