Hey there! I'm happy to help!
When you read a sentence and you hear the same sound at the beginning of a few consecutive words, that is called alliteration. This is a type of a figurative language where the beginning of each word has the same consonant sound at the beginning.
For example...
Jubilant jumping jaguars jump into the jester's jello.
In our problem, we see that is says "cleary confused". These both have the c sound at the beginning, so it is alliteration.
Have a wonderful day! :D
