113的D项og 的解释我看不懂，可否讲解一下~~
121的详细解答~
多谢！！
题目：
113. The average hourly wage of television assemblers in Vernland has long been significantly lower than that in
neighboring Borodia. Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of
televisions sold annually in Borodia has not changed. However, recent statistics show a drop in the number of
television assemblers in Borodia. Therefore, updated trade statistics will probably indicate that the numberof
televisions Borodia imports annually from Vernland has increased.
Which of the following is an assumption on which the argument depends?
(A) The number of television assemblers in Vernland has increased by at least as much as the number of
television assemblers in Borodia has decreased.
(B) Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
(C) The average number of hours it takes a Borodian television assembler to assemble a television has not
decreased significantly during the past three years.
(D) The number of televisions assembled annually in Vernland has increased significantly during the past
three years.
(E) The difference between the hourly wage of television assemblers in Vernland and the hourly wage of
television assemblers in Borodia is likely to decrease in the next few years.
og的解释：
D Tlie argument does not depend upon this being so: Vernland's domestic TVsales (or perhaps its
exports to countries otherthan Borodia) may have decreased by more than its imports into
Borodia have increased.
==============================
121. The spacing of the four holes on a fragment ofa bone flute excavated at a Neanderthal campsite is just what is
required to play the third through sixth notes of the diatonic scale—the seven-note musical scale used in much
of Western music since the Renaissance. Musicologists therefore hypothesize that the diatonic musical scale
was developed and used thousands of years before it was adopted by Western musicians.
Which of the following, iftrue, most strongly supports the hypothesis?
(A) Bone flutes were probably the only musical instrument made by Neanderthals.
(B) No musical instrument that is known to have used a diatonic scale is of an earlier date than the flute found
at the Neanderthal campsite.
(0 The flute was made from a cave-bear bone and the campsite at which the flute fragment was excavated
was in a cave that also contained skeletal remains of cave bears.
(D) Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.
(E) The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute
capable of playing a complete diatonic scale. |
