You may sometimes be given a 2-part question which will require 2 different approaches, in which case you must state each answer clearly and separately:
Question:
a) Define what is meant by the term ‘grey water’
b) Explain the advantages of grey water recycling
Answer:
a) Grey water is waste water generated by activities in the home such as bathing, laundry & dishwashing
b) The advantages of grey water recycling are:
1. It is easy to install and is maintenance free.
2. It removes the need for complex water treatment
3. It can lower sewage costs
4. It can reduce groundwater usage for irrigation purposes
5. Less water will enter city’s sewage systems and so saves on rebuilding old sewage treatment plants
To summarise:
- Always start by writing out the question first and reading it very carefully
- Aim to keep your answers short and to the point
- Clearly label your answers
