okay . this question sounds funy at frst look, but it realy is simple. according to the mark scheme, u get:
4 marks for giving meaning of money and division ov labour
4 marks for giving the impact money has had on the economy
4 marks for giving the impact division of labour has had on the economy
theres ur 8 marks, the rest of the 4 marks are for ur judgement, well if u look at it logically, i think division of labour did the better job, no? =)
