Recall previously given answer in next question or slide

Would it be possible to recall an answer a student has given in the course, to have them continue working with that information at a later stage in the course. For instance - say that one of the questions asks the student to write down 5 words they didn't understand from the previous slide. Then later in the lesson or in a later lesson, have a question that says: Earlier you indicated that you did not understand these words: "student's answer" - look up the definition of these words in the dictionary and write them down in the Answer box. Cause that would be awesome :).
