Sports bars that do not already have rooms with separate HVAC systems need to construct them in order to accommodate patrons who wish to smoke, or the lack of a smoking room will cause these bars to go out of business. Which of the following, if true, would most strengthen the argument above? A. Smoking patrons care enough about being able to smoke in a sports bar that they would leave bars without smoking rooms in favor of those with smoking rooms in large enough numbers to drive the bars without smoking rooms out of business. B. Employees of sports bars without smoking rooms are known to smoke outside during breaks, and patrons are welcome to do the same without breaking the law. C. Most patrons of the average sports bar do not smoke anyway and will shy away from bars that do have smoking rooms. D. The new smoking legislation should provide equal protection from any hazards associated with smoking to all patrons of restaurants and bars. E. To construct a new smoking room, bars will need all the proper construction licenses, a certified contractor, and a plan from an architect. Construction will take at least three months for the average bar. - Answer A. A. 5 - Answer If 2^2p-10 = 2(2^9-2p), then p = A. 5 B. 3 C. 0 D. -1 E. -2 In several states, legislation has been proposed that would make smoking cigarettes illegal.

Exposure to smoke wafting from lit cigarettes or from the exhalation of a smoker--otherwise known as secondhand smoke--has been shown to increase the risk of lung cancer in non-smokers. B. Smokers do not enjoy the same life expectancy as non-smokers and therefore often leave dependents without a source of support when the smokers die prematurely. C.

Homeowner's insurance premiums for all customers are more expensive because some smokers are known to light houses on fire by not fully extinguishing cigarettes. - Answer D. B. This is a weaken question. Conclusion is after the therefore. - Answer Gas-fired and oil-fired power plants emit some pollutants into the air. However, coal-fired plants, as presently engineered, emit far more noxious air pollutants, causing acid rain to fall hundreds of miles away from the plants themselves. Therefore, in order to reduce air pollution, we should close down the coal-fired plants and replace them with gas- and oil-fired plants. Which of the following, if true, would most weaken the conclusion above? A. In addition to the air emissions from coal-fired power plants, mining coal can pollute water, while gas and oil-fired plants pollute only air. B. Coal plants can easily be redesigned to eliminate most emissions into the atmosphere. C. Gas-fired power plants are more cost efficient than coal-fired power plants. D. As supplies of oil decline, the demand for natural gas and coal will increase. E. Engineers have developed a model to reduce emissions from oil and gas-fired plants to an imperceptible amount. The interview is an essential part of the graduate school admissions process because, with it, students who have personalities that are unsuited to the area of study and course requirements will be eliminated from consideration. The argument above logically depends on which of the following assumptions? A. An admissions program will admit the best applicants if it includes interviews. B. The interview is a more significant part of a successful admissions program than is the development of the course of study. C. Admissions officers can accurately identify applicants whose personalities are not suited to the area of study. D. The only purpose of an interview is to evaluate whether graduate school candidates' personalities are suited to the area of study. E. The fit of graduate school applicants' personalities to the course requirements was once the most important factor for making admissions decisions. - Answer C. Explanation: If admissions officers could not accurately identify unsuitable applicants, then interviews couldn't play such an essential role in the admissions program. So the argument depends on (C) being true. C. - Answer From January 1, 2002 to July 1, 2002, the median household income in Country X increased by 2%.
