                     This question  was fairly attempted by the candidates. In 2 (b)(i), many candidates could not  write the full meaning of WARDA. Also, in question 2 (c)(ii), some candidates  were unable to state the functions of mistblower. 
                    However, in  question 2 (a), majority of the candidates were able to state the ways by which  agriculture has contributed to the development of national economy.  Further to this, in 2(b)(i) and 2(c)(i and  iii), most candidates could write the full meaning of IITA and state the  functions of bulldozer and harrow. 
                    The expected answers include: 
                    Full meaning of  acronyms of non-governmental agricultural organizations: 
                    WARDA – West Africa Rice Development Association.
