At long last, the end of the first semester has come, but that just means an even greater challenge: final exams. Things take a strange turn when it appears there is no examiner. Is this a trick to get the C-type students to let their guard down? But a shadowy figure appears with a familiar voice.
So if I create a vacuum, 
your voice won't reach anymore!
إذاً إن صنعتُ فراغاً، لن يصل صوتك لأحد
Wenn ich also ein Vakuum erzeuge,
kommt deine Stimme nicht mehr durch!
Si hago un vacío,
tu voz no me alcanzará.
Si creo un vacío,
tu voz no me alcanzará.
Si je crée une zone de vide,
ta voix ne pourra plus m’atteindre !
Se creo il vuoto, la tua voce
non arriverà più da nessuna parte!
Se eu criar uma área com vácuo,
 a sua voz não vai me alcançar!
