In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years. Since many local businesses in Florida cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses.
Which of the following, if true, most seriously weakens the argument?
C. There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.

GWD1-Q14:
That the application of new technology can increase the productivity of existing coal mines is demonstrated by the case of Tribnia’s coal industry. Coal output per miner in Tribnia is double what it was five years ago, even though no new mines have opened.
Which of the following can be properly concluded from the statement about coal output per miner in the passage?
A. If the number of miners working in Tribnian coal mines has remained constant in the past five years, Tribnia’s total coal production has doubled in that period of time.

GWD1-Q15:
In parts of South America, vitamin-A deficiency is a serious health problem, especially among children. In one region, agriculturists are attempting to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in beta-carotene, which the body converts into vitamin A. The plan has good chances of success, since sweet potato is a staple of the region’s diet and agriculture, and the varieties currently grown contain little beta-carotene.
Which of the following, if true, most strongly supports the prediction that the plan will succeed?
A. The growing conditions required by the varieties of sweet potato currently cultivated in the region are conditions in which SPK004 can flourish.

GWD1-Q17:
The spacing of the four holes on a fragment of a 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, if true, most strongly supports the hypothesis?
A. Bone flutes were probably the only musical instrument made by Neanderthals.

The following appeared in a report presented for discussion at a meeting of the directors of a company that
manufactures parts for heavy machinery:
“The falling revenues that the company is experiencing coincide with delays in manufacturing. These delays, in turn,
are due in large part to poor planning in purchasing metals. Consider further that the manager of the department that
handles purchasing of raw materials has an excellent background in general business, psychology, and sociology,
but knows little about the properties of metals. The company should, therefore, move the purchasing manager to the
sales department and bring in a scientist from the research division to be manager of the purchasing department.”
Discuss how well reasoned . . . etc. |
