1.(Z)Lawmaker: Raising taxes is not the only means of reducing government
debt. The government’s stockpile of helium is worth 25 percent more, at current market prices, than the debt accumulated in acquiring and storing it. Therefore, by selling the helium, the government can not only pay off that debt but reduce its overall debt as well.
Which of the following is an assumption on which the argument depends?
A. The government has no current need for helium.
B. Twenty-five percent of the debt the government has accumulated in
Stockpiling helium is not an insignificant portion of the government’s
Total debt.
C. It is not in the lawmaker’s interest to advocate raising taxes as a
Means of reducing government debt.
D. Attempts to sell the government’s helium will not depress the market
Price of helium by more than 25 percent.
E. The government will not incur any costs in closing its facilities for
stockpiling helium.
2.(Z)Excavations of the Roman city of Sepphoris have uncovered numerous detailed mosaics depicting several readily identifiable animal species: a hare, a partridge, and various Mediterranean fish. Oddly, most of the species represented did not live in the Sepphoris region when these mosaics were created. Since identical motifs appear in mosaics found in other Roman cities, however, the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.
Which of the following is an assumption on which the argument depends?
A. The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area.
B. There is no single region to which all the species depicted in the Sepphoris mosaics are native.
C. No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.
D. All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.
E. There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.
