Didn´t Manny bring tools and help with the cleanup?
The answer that identifies the compound verb is "Didn't bring/help".
"Didn't bring (auxiliary + verb) functions as a compound verb since a compound verb is a verb which is made up of more than one word, for example: the verb with auxiliaries. At the same time, "Didn't" is also acting as the auxiliary of the verb "help", that's why the correct option is the first one (Didn't bring, help).
It is important to state that there are several types of compound verbs such as prepositional verbs (e.g. ask for), phrasal verbs (e.g. look after), verbs with auxiliaries (e.g. have been), and compound single-word verbs (e.g. water-proof).
