Though popular among candidates but most poorly handled.  Most candidates wrote their own ideas and not what Paul taught.  They did not mention such points as;

1.  Singing psalms, hymns and spiritual songs with thanksgiving
2. Teaching and admonishing one another in all wisdom of God                     
3. Let the word of God dwell richly in you.

However in the (b) part of the question, they applied residual knowledge and
were able to point out those practices that can have negative effect on Christian Community like:

1. Examination malpractice;
2. Greed and selfishness;
3. Ritual sacrifices;
4. Kidnapping.

The overall performance was a little above average.
