Break the answer into parts, each consisting of one sentence. Learn one sentence. Cover the page and recite the sentence. Learn another sentence. Cover the page and recite both the sentences. Learn the third sentence. Cover the page and recite all the three sentences. Do this until you are able to recite the whole answer. After that, recite it five more times. Take a short break of five minutes. Say it one more time. If you can, then you have learned the answer. You can also try recording your answers. You can listen to it all the time.
