Question Regarding question-answering architecture

[qwertyatp]

Do the models in the model zoo answer only single-word answers, or can they be used for answer generation where the answer consists of multiple words?

Thanks,

They can be used for generating the answer with multiple words.
It is achieved under a classification framework regarding each answer (can be either a single word or multiple words) as an individual class.
