A reasonable number of candidates that attempted this question could not do justice to it and so the low marks. But some wrote about how the angel came to the prison and liberated peter.  Others wrote about the outcome of the opposition.  The (b) part of the question was their undoing as only few gave the correct answers.  The points they would have mentioned are:

(i)         Believers were scattered abroad;
(ii)        Christians went to hide;
(iii)       Led to war and persecution
(iv)       Led to the loss of lives and property.

The overall performance was just average.
