Final answer:
Mohammed Mounir's song "Essai" was not censored by the Egyptian government because it used metaphorical language to criticize President Mubarak.
Step-by-step explanation:
Mohammed Mounir's song, "Essai" or "How?", was not censored by the Egyptian government even though it criticized President Mubarak because it used metaphorical language to express its message. By using indirect and symbolic language, Mounir was able to convey his criticism without directly attacking the president. This allowed the song to pass censorship since it did not violate the government's guidelines for acceptable speech.
