Various studies have shown that our forested and hilly regions and, in general, areas where biodiversity-as reflected in the variety of flora-is high, are the places where poverty, appears to be high. And these same areas are also the ones where educational performance seems to be poor. Therefore, it may be surmised that, even disregarding poverty status, richness in biodiversity goes hand in hand with educational backwardness. Which one of the following statements, if true, can be said to best provide supporting evidence for the surmise mentioned in the passage?
The correct option
is D (d) In regions where there is low biodiversity, at all levels of
poverty, educational performance is seen to be good.
(d) The surmise is that the level of biodiversity is linked inversely to
educational standards. The reverse thinking also works, that is, low level of
biodiversity will result in high level of educational standard. This is aptly
brought out in statement (4) and would best provide supporting evidence for the
surmise. The first statement does not strengthen the surmise since levels in
biodiversity shares a direct relationship with educational standards at a high
level of poverty, which is fallacious. The second and third statement though
exhibiting inverse relationship between levels in biodiversity and educational
standards applies only to low and high levels of poverty respectively which
goes against the surmise, which is that this inverse relationship between
biodiversity and educational standards holds valid for all levels of poverty.
