A) "To him, your celebration is a sham; your boasted liberty, an unholy license; your national greatness, swelling vanity." This sentence is an instance of parallellism. The same pattern is repeated- look at the underlined words-. Subject + to be + complement. However, this pattern is used in "your celebration is a sham". In the other two structures the verb to be has been omitted and a comma has been used,instead. " your boasted liberty, (is) an unholy license; your national greatness, (is) swelling vanity." The verb to be can be taken out since it can be easily retrieved from the context. If it is ellided, it should be replaced by a comma.
