                  | This  question was very popular among the candidates.   In 9(a), majority of the candidates were able to state six factors that  affect the demand for agricultural produce.   Further to this, in 9(b) (i-iv), most of the candidates could calculate  the useful life, salvage value, total depreciation and annual depreciation of  the power tiller.  More so, majority of  the candidates could state four advantages of using mass media as an  agricultural extension teaching method as required in 9(c).   |
