This question was well attempted by the candidates .  In 5(a), most of the
candidates  were able to define elasticity of demand.  Further to this, in 5b, though majority of them could explain the term collateral, only a few of them were able to explain farm inventory record.  In 5(c), most of the candidates were able to state the merits and demerits of the retailer but majority of them could not state the roles of testosterone and progesterone in animal reproduction as required in 5 (d).  Although, majority of them were able to list the ways of preserving fish as required in 5 (e).

The expected answers include:
5b(ii)    Farm inventory record
This is a detailed list of all assets or materials on the farm including their money
