B and C hoped it helped. I am on the same question as you were xD!
A. Recall a familiar text.
An allusion is a reference to another published work. In this case, the allusion is to the Pledge of Allegiance. Instead of the just saying the name of the text, the author alludes to it by quoting the first line. For readers who know the Pledge of Allegiance this may spark in them a sense of patriotism as they may then recite the entire pledge. The reader uses this allusion to further the point about patriotism as a routine taught in schools.

An unabridged dictionary of English language attempts to cover all the words and gives information. I hope I helped you...
