Nigeria's Economy - 1st in Africa

I couldnt help but laugh when I heard that the coordinating Minister of the country, Mrs Okonjo Iweala said Nigeria as overtaken South Africa to emerge as the largest economy in Africa. "Please, where
did she get her facts from?" That was the question I asked, only to be told that we (Nigeria) conducted the survey ourselves. Hahahahaha What do you expect of a student whom the teacher asked to grade him/herself? Do you expect the student to fail him/herself? Madam Coordinating Minister, please be serious at least for once. Just me thinking out loud.
