Q 23:
Discussion of greenhouse effects has usually focused on whether the
Earth would warm and by how much, but climatologists have indicated all
along that the most obvious effects, and those that would have the larg-
est impact on people, would be extremes of temperature, precipitation,
and storminess .
A. the most obvious effects, and those that would have the largest
impact on people, would be extremes of temperature,
precipitation, and storminess
B. the effects that are the most obvious ones, extremes of temper-
ature, precipitation, and storminess, would be those impacting
the most on people
C. those effects to have the largest impact on people, extremes of
temperature, precipitation, and storminess, are what are the
most obvious effects
D. extremes of temperature, precipitation, and storminess, the most
obvious effects, that they would have the largest impact on people
E. extremes of temperature, precipitation, and storminess, which are
the most obvious effects, are those to impact the most on people

Q 24:
Many winemakers use cork stoppers; but cork stoppers can leak, crumble, or become
moldy, so that those winemakers must often discard a significant proportion of their
inventory of bottled wine. Bottlemaster plastic stoppers, which cannot leak, crumble,
or mold, have long been available to winemakers, at a price slightly higher than that
of traditional cork stoppers. Cork prices, however, are expected to rise dramatically in
the near future. Clearly, therefore, winemakers who still use cork but wish to keep
production costs from rising will be forced to reconsider plastic stoppers. And
since the wine-buying public’s association of plastic stoppers with poor-quality wine
is weakening, there is an excellent chance that the Bottlemaster plastic stopper
will gain an increased share of the marked for wine-bottle stoppers.
In the argument given, the two portions in boldface play which of the following
roles?
