Please answer the following question. Thank you.

Your examples should demonstrate all the possibilities represented in the rules. (name) :-(object-ref? [ . ?identifier) ] (object-ref):?(identifier) \ ?method-call? (identifier) - "a" | "x" | "y" | "z" (method-call): (dentfier) "(" ?name) I "," ?name) ] ")
