Official ExplanationThat the economy expands at a certain pace is described as
“a problem.” This happens when
“wages of the middle class are stagnant,” showing no activity or only sluggishly growing. The blank, then, likely refers to a sluggish or slow pace of economic expansion.
“Lucrative” and
“profitable” are synonymous with each other, but imply economic growth, which would not be a problem. An
“exponential” pace would be one that increases at a faster and faster rate, which is opposite the idea of
“stagnant” wages or a
“problem” with the economy. If the economy expands at a
“normal” pace, the expansion is typical or expected, which is not negative enough. Only
“plodding,“ which means slow-moving, and
“pedestrian,” which means dull, fit the meaning of the sentence and produce sentences that are alike in meaning.
