If i'm understanding your question correctly. You want to change the question according to the current answer. You can use the useEffect hook to accomplish that. Assuming you want to subscribe to the changes of the variable item.

useEffect(()=>{
    setQuestion(response.pathway.answers[item].question);
},[item]);
