A severe drought can actually lessen the total amount of government aid that United States farmers receive as a group. The government pays farmers the amount, if any, by which the market price at which crops are actually sold falls short of a preset target price per bushel for the crops. The drought of 1983, for example, caused farm-program payments to drop by $10 billion.
Given the information above, which of the following, if true, best explains why the drought of 1983 resulted in a reduction in farm-program payments?
(A) Prior to the drought of 1983, the government raised the target price for crops in order to aid farmers in reducing their debt loads.
(B) Due to the drought of 1983, United States farmers exported less food in 1983 than in the preceding year.
(C) Due to the drought of 1983, United States farmers had smaller harvests and thus received a higher market price for the 1983 crop than for the larger crop of the preceding year.
(D) Due to the drought of 1983, United States farmers planned to plant smaller crops in 1984 than they had in 1983.(C)
(E) Despite the drought of 1983, retail prices for food did not increase significantly between 1982 and 1983.
The only purpose for which a particular type of tape is needed is to hold certain surgical wounds closed for ten days—the maximum time such wounds need tape. Newtape is a new brand of this type of tape. Newtape's salespeople claim that Newtape will improve healing because Newtape adheres twice as long as the currently used tape does.
Which of the following statements, if true, would most seriously call into question the claim made by Newtape's salespeople?
(A) Most surgical wounds take about ten days to heal.
(B) Most surgical tape is purchased by hospitals and clinics rather than by individual surgeons.
(C) The currently used tape's adhesiveness is more than sufficient to hold wounds closed for ten days.
(D) Neither Newtape nor the currently used tape adheres well to skin that has not been cleaned.(C)
(E) Newtape's adhesion to skin that has been coated with a special chemical preparation is only half as good as the currently used tape's adhesion to such coated skin.
In the course of her researches, a historian recently found two documents mentioning the same person, Erich Schnitzler. One, dated May 3, 1739, is a record of Schnitzler's arrest for peddling without a license. The second, undated, is a statement by Schnitzler asserting that he has been peddling off and on for 20 years.
The facts above best support which of the following conclusions?
(A) Schnitzler started peddling around 1719.
(B) Schnitzler was arrested repeatedly for peddling.
(C) The undated document was written before 1765.
(D) The arrest record was written after the undated document.(C)
(E) The arrest record provides better evidence that Schnitzler peddled than does the undated document.
Advertisement: The world's best coffee beans come from Colombia. The more Colombian beans in a blend of coffee, the better the blend, and no company purchases more Colombian beans than Kreemo Coffee, Inc. So it only stands to reason that if you buy a can of Kreemo's coffee, you're buying the best blended coffee available today.
The reasoning of the argument in the advertisement is flawed because it overlooks the possibility that
(A) the equipment used by Kreemo to blend and package its coffee is no different from that used by most other coffee producers
(B) not all of Kreemo's competitors use Colombian coffee beans in the blends of coffee they sell
(C) Kreemo sells more coffee than does any other company
(D) Kreemo's coffee is the most expensive blended coffee available today(C)
(E) the best unblended coffee is better than the best blended coffee
In order to increase revenues, an airport plans to change the parking fees it charges at its hourly parking lots. Rather than charging $2.00 for the first two-hour period, or part thereof, and $1.00 for each hour thereafter, the airport will charge $4.00 for the first four-hour period, or part thereof, and $1.00 for each hour thereafter.
Which of the following is a consideration that, if true, suggests that the plan will be successful in increasing revenues?
(A) Very few people who park their cars at the hourly parking lot at the airport leave their cars for more than two hours at a time.
(B) Over the past several years, the cost to the airport of operating its hourly parking facilities has been greater than the revenues it has received from them.
(C) People who leave their cars at the airport while on a trip generally park their cars in lots that charge by the day rather than by the hour.
(D) A significant portion of the money spent to operate the airport parking lot is spent to maintain the facilities rather than to pay the salaries of the personnel who collect the parking fees.(A)
(E) The hourly parking lots at the airport have recently been expanded and are therefore rarely filled to capacity.
