Observation
In the first place, this question was well attempted by the candidates. In 1(a - b), most of the candidates were able to state the methods of removing specimen A (Horn) from animals as well as give the reasons why specimen A (Horn) may be removed from an animal. Also, in 1(c-d), majority of them were able to mention the methods of preserving specimen B (Fresh meat) but they could not state the ways in which specimen C (Honey) is of importance to humans.

As a matter of fact, this question was poorly attempted y the candidates. Most of the candidates could not state the features of specimens D(Sickle) and F (Watering trough) as required in 2(a) but they were able to give the uses of specimens D (Sickle), E (Feeding trough) and G(Knife) as required in 2(b).
Furthermore, majority of the candidates were unable to state the maintenance practices for specimens D(Sickle), E(Feeding trough), F(Watering trough) and G(Knife) as required in 2(c).

(c) Mention four benefits of planting specimens L and M together in a pasture. [4 marks]
(d) Describe how specimen K is produced using the dry process. [3 marks]

Meanwhile, their functions but majority of them were unable to name the major nutrients found in specimens L (Elephant grass) and M (Calopogonium) as well as their functions.
Furthermore, in 3(c), most of the candidates were able to mention the benefits of planting specimens L(Elephant grass) and M(Calopogonium) together in a pasture. More so, majority of them were able to describe how specimen K(Bone meal) is produced using the dry process as required in 3(d).
The expected answers include:
3 (a) Major nutrients found in Specimens J, K, L and M
