Answer: The syllable that should be accented in "celebration" is "bra".
Explanation: The word "celebration" has four syllables: "cel", "e", "bra" and "tion". However, <u>the syllable that should be accented is the third one, "bra"</u>. In that way, <u>"bra" is the one that should be emphasized and pronounced longer and louder that the others</u>. On the other hand, "cel", "e" and "tion" need to be pronounced softer and at a lower pitch than "bra".
