Answer:
Words that look alike: <em>a </em>means <em>have</em><em>,</em><em> </em><em>à </em>means <em>to.</em><em> </em><em>où </em>means where, <em>ou</em><em> </em>means or.
The title might be <em>Accent </em><em>Grave </em>because the teacher is trying to be serious about conjugating the verb, <em>être,</em> while Hamlet is being serious about the meaning of <u>where</u> we are in life-- or in daydreams-- , and the meaning of <u>choices</u> as <em>"</em><em>to </em><em>be </em><em><u>or</u></em><em> </em><em>not</em><em> </em><em>to </em><em>be.</em><em> </em><em>.</em><em> </em><em>.</em><em>"</em><em> </em>
That is an allusion to Hamlet's famous soliloquy in the play by Shakespeare.
The title is a pun. In French, grave means "serious" but it is also the accent mark that differentiates <em>ou </em>from où. In English, <em>grave </em>has different meanings, sharing the "serious" definition with the French, but also meaning the excavation where a dead body is buried.
This may be an allusion to the scene in Act V where Hamlet and Laertes fight in the newly-dug grave of Ophelia about their love for her.
