In Grenada, use of solid fuel (e.g.. coal, wood) as a share of total household fuel use fell by more than a third between 2000 and 2019; such shifts are often explained by appeal to the energy ladder, a model holding that fuel choice is mediated mainly by household income (specifically, high-technology fuels displace solid fuels as incomes rise). Moses Pundo and Gavin Fraser's study of fuel use in Kenya shows this model to be reductive, however: household fuel use was heterogeneous, flexible, and influenced by several factors, including the age of the household head.
Which choice best describes the function of the information about Grenada in the text as a whole?
It provides an example of a type of change that the text goes on to suggest is poorly suited for evaluating whether the energy ladder is a viable model.
A
It introduces a finding that the text goes on to suggest can be explained in two different ways that are equally compelling.
B
It illustrates the kind of phenomenon that the text goes on to suggest is frequently but inadequately accounted for by the energy ladder.
C
It describes a trend that the text goes on to suggest has a similar cause as a seemingly unrelated trend observed in Kenya.
D
