NVQ Web - Health and Social Care

I am nearly finished with this unit and just need to answer these three questions but I am stuck, can anyone help plesae?

KS 3: the specific legislation [national and european] which relates to the work
undertaken and how this has been taken into account
KS 9: the ways in which feelings of anger and frustration can be displaced from
their original source to those in authority and how to deal with this.
KS 13: the ways in which individuals' culture and gender influence your practice.

Many thanks
Keri
