OBSERVATION

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:
