求问陈虎平36套exercise 11, 第12题

Geologists have long known that the Earth‘s mantle
is heterogeneous, but its spatial arrangement remains
unresolved—is the mantle essentially layered or irregu-
larly heterogeneous? The best evidence for the layered-
mantle thesis is the well-established fact that volcanic
rocks found on oceanic islands, islands believed to
result from mantle plumes arising from the lower
mantle, are composed of material fundamentally
different from that of the midocean ridge system,
whose source, most geologists contend, is the upper
mantle.
Some geologists, however, on the basis of obser-
vations concerning mantle xenoliths, argue that the
mantle is not layered, but that heterogeneity is created
by fluids rich in ―incompatible elements‖ (elements
tending toward liquid rather than solid state)
percolating upward and transforming portions of the
upper mantle irregularly, according to the vagaries of
the fluids‘ pathways. We believe, perhaps
unimaginatively, that this debate can be resolved
through further study, and that the underexplored
midocean ridge system is the key.




12. In the context of the passage, ―unimaginatively‖ is
closest in meaning to
(A) pedestrian
(B) controversial
(C) unrealistic
(D) novel
(E) paradoxical


为什么选A迂腐的呢？

我们是不需要想象力的相信更进一步的研究可以解决这个争论这点，也就是我们固执滴甚至略带迂腐的相信，而毫不怀疑，也不去做其他的想象，五个单词，我觉得A是最接近的，当然跟愿意略有差异
