So when the prompt asks for 3 examples of powerful language, it's asking for something that makes an impact. It's powerful, and it make you think. Kind of like figurative language or metaphors. That's just what I think though...
Squelch, slap, soggy
curt cuts
Alliteration is the repetition of sounds at the beginning of a group of words. In this case there are two different groups of words that could be examples of alliteration. The first is in the section "the squelch and slap of soggy meat". The /s/ sound is repeated at the beginning three times in this part of the excerpt. The second is "curt cuts". In this two word phrase, the hard /c/ sound is repeated.
Keep in mind when identifying alliteration it's important to hear the sound the word makes. Sometimes when you just look for a repeated letter it is incorrect. For example, the circular cheese is cut. Even though a majority of words begin with c, none of them begin with the same sound.
