This question was not very popular among the candidates.  In 1(a) majority of the candidates were able to explain what is meant by subsistence agriculture.

However in 1(b)(i-iii), majority of the candidates were not able to discuss correctly the interdependence of agriculture and industry under tools, implements and machinery industries; processing industries and agro-chemical industries.  In 1(c)(i) most of the students could explain what is meant by farm surveying but in 1(c)(ii) most of the candidates could not use a diagram to explain the use of the 3, 4, 5 method in farm survey.
The expected answers include:
  (b)      Discussion on the interdependence of agriculture and industry
            (i)       Tools, implements and machinery industries

• The increasing high demand for agricultural produce and the need to process and store them have given rise to mechanization.
• Farm machinery and implements have been manufactured by various industries and local artisans to carry out various operations in agriculture.
• Local blacksmithing workshops  produce tools such as hoes, machines for  grinding and  milling of farm produce.

            (ii)       Processing Industries

• Most agricultural produce are perishable and bulky in nature
• They require some form of processing and storage prior to their consumption and marketing in future.
• This has led to the establishment of processing industries e.g. industries processing fruits, tubers, fibres, milk etc.

(iii)       Agro-chemical industries

• In order to boost agricultural production, farmers demand for agro-chemicals such as                       fertilizers, pesticides, herbicides and fungicides has been on the increase.
• Veterinary drugs as well as feed additives are also required in animal production.

                                    3, 4, 5 – method in farm survey

• From the point in figure X where the right angle is to be marked, 3 metres are measured back to point C and
• Pegs are stuck into the ground at A and C;
• A piece of cord 4 metres long is tied to the peg at A and one 5 metres long tied to the peg at C.
• The two pegs are stretched out and another peg is struck into the ground where the cords meet at B.  The angle marked at A is now a right angle.
