This question was sparingly attempted by the candidates and their performance in it was poor. They mixed it up with the prophecy of Jeremiah and Ezekiel their write up did not show mastery of the subject and the question.
They were supposed to highlight the New Covenant in each of Jeremiah and Ezekiel. The contents of each covenant differ from the other. In that of Jeremiah most candidates forgot to mention that:

(i) The people had broken the Sinai Covenant.
(ii) The people would not need to be taught to "know the Lord".

In that of Ezekiel they were supposed to mention that; God would cleanse them of idols, He would put in them a new heart and new spirit and replace the stoney heart with the heart of flesh.
