此类两组黑体字play roles的题型总是不太会搞 求大侠帮助
117. Scientists typically do their most creative work before the age of forty. It is commonly thought that this happens
because aging by itself brings about a loss of creative capacity. However, studies show thatof scientists who
produce highly creative work beyond the age of forty, a disproportionately large number entered
their fi eld at an older age than is usual. Since by the age of forty the large majority of scientists have been
working in their fi eld for at least fi fteen years, the studies’ fi nding strongly suggests that the real reason why
scientists over forty rarely produce highly creative work is not that they have aged but rather that scientists
over forty have generally spent too long in their field.
In the argument given, the two portions in boldface play which of the following roles?
(A) The fi rst is a claim, the accuracy of which is at issue in the argument; the second is a conclusion drawn on
the basis of that claim.
(B) The fi rst is an objection that has been raised against a position defended in the argument; the second is
that position.
(C) The fi rst is evidence that has been used to support an explanation that the argument challenges; the
second is that explanation.
(D) The fi rst is evidence that has been used to support an explanation that the argument challenges; the
second is a competing explanation that the argument favors.
(E) The fi rst provides evidence to support an explanation that the argument favors; the second is that
explanation
124. Museums that house Renaissance oil paintings typically store them in environments that are carefully kept within
narrow margins of temperature and humidity to inhibit any deterioration. Laboratory tests have shown that the
kind of oil paint used in these paintings actually adjusts to climatic changes quite well. If, as some museum
directors believe, paint is the most sensitive substance in these works,then by relaxing the standards for
temperature and humidity control, museums can reduce energy costs without risking damage to these
paintings. Museums would be rash to relax those standards, however, since results of preliminary tests indicate
that gesso, a compound routinely used by Renaissance artists to help paint adhere to the canvas, is unable to
withstand signifi cant variations in humidity.
In the argument above, the two portions in boldface play which of the following roles?
(A) The fi rst is an objection that has been raised against the position taken by the argument; the second is the
position taken by the argument.
(B) The fi rst is the position taken by the argument; the second is the position that the argument calls into
question.
(C) The fi rst is a judgment that has been offered in support of the position that the argument calls into
question; the second is a circumstance on which that judgment is, in part, based.
(D) The fi rst is a judgment that has been offered in support of the position that the argument calls into
question; the second is that position.
(E) The fi rst is a claim that the argument calls into question; the second is the position taken by the argument. |
