Question 2
Study specimens I, J, K and L carefully and answer the following questions.
(a)(i). Give two uses each of specimens I(Wheelbarrow) and J (File)
(ii) State two general ways of maintaining specimens I and J. [6 marks]
(b) (i) Give the botanical names of the crops from which each of specimens K (Palm oil) and L (Cotton lint) were obtained.
(ii) Outline the steps involved in the traditional method of producing specimen K.[9 marks]
Observation
T(a) (i) On the use of wheelbarrow and file, most candidates did not use appropriate register. For instance candidates stated that file was used for ‘filling’ cutlass instead of ‘sharpening’ cutlass. (ii) It is very fulfilling to note that majority of the candidates provided correct answers to general ways of maintaining farm tools. (b) (i) Writing of botanical name is still a problem to majority of the candidates as they failed to adhere strictly to the rules. (ii). Most candidates also did not provide correct answer to the steps involved in making palm oil traditionally.
The expected answers include:
2.(b)(i) Botanical names of crops from which specimens K(Palm oil) and L(Cotton lint) were obtained
Specimen K: Elaeis guineensis
Specimen L: Gossypium spp/Any specific species
(ii) Steps involved in the traditional method of producing specimen K (Palm oil)
- Boil the fruits
- Pound the boiled fruits in a mortar
- Add water to the mixture
- Stir the mixture vigorously
- Wash and remove the fibre/nuts
- Separate the oil from water by floatation
- Boil the crude liquid
- Separate the oil from water
- Re-heat the oil to eliminate any trace of water by evaporation
