­In Country X in 1996, 84% of political donations from businesses came from those with annual sales of over $100 million. In that same year, 24 companies in the software industry, all of which had shown increases in the valuation of their stock of over 40% in the preceding year, accounted for 19% of business political donations.

If the above statements are true, which of the following must also be true?

(A) Computer companies made more political donations than did pharmaceutical companies.
(B) At least one of the businesses with annual sales of over $100 million showed an increase in the value of its stock in 1995.
(C) Most software companies had sales of less than $100 million in 1995.
(D) Individual contributions accounted for 16% of all political campaign contributions.
(E) The stock of most businesses with annual sales over $100 million did not increase by over 40% in 1996.

CR 2

­A local councilman has proposed a “sin tax” on alcoholic beverages served in area bars. The councilman believes that since the amount of the tax alone will exceed the cost of most non-alcoholic beverages, many people will switch from alcohol to other beverages.

Which of the following statements, if true, would most clearly indicate a vulnerability in the councilman’s argument?

A. Both beer and hard liquor will be taxed under the councilman’s proposal.
B. The cost of alcoholic beverages is already considerably higher than that of any non-alcoholic beverage.
C. Many people abstain from alcohol for moral or religious reasons.
D. The “sin tax” should apply to cigarettes instead because smoking causes more preventable deaths than does alcohol.
E. Many bar patrons consume more alcohol on days when they are paid.

(1) If the next six signers are all residents, the ratio of residents to nonresidents in the database will be 1 : 1

(2) If three signers had been incorrectly assigned and were nonresidents rather than residents, the ratio of residents to nonresidents in the database would be 1: 3 once this was corrected.

CR 1

­A successful clothing department store, in a central downtown location of a certain city, is of a limited size and has grown so much over the past year that it needs to expand. There are a few other slightly larger available retails lots in the downtown regions for sale, but the prices per square foot are quite high. The management finds that cost per square foot of lots in a suburb a few miles from downtown is almost half of that in the downtown region, so they plan to relocate there to save costs.

Which of the following, if true, most seriously undermines this plan?

A) The store will have to adapt to the building codes of the suburb, which may not be the same as the city.
B) The lot for the suburb location will require a sprawling parking lot.
C) Consumers from the city who do not own cars will have to pay bus fare to commute to this store now.
D) Almost all of the store's other locations, in other metropolitan regions throughout the state, are in downtown areas; very few are in suburbs.
E) Some of the available downtown locations, though only a few blocks away, would be closest to entirely different bus and subway lines.
___________________________
CR 2

Mountain County and Sunrise County are two comparable counties, with similar numbers of registered voters. Both are in the same region of the state. In both counties, about 60% of the registered voters are registered Republicans, and almost all others are registered Democrats. In 2005, Republican candidate Alf Landon ran for supervisor of Mountain County, and Republican candidate Thomas Dewey ran for supervisor of Sunrise County. Both took similar stands on issues, and both ran against conservative Democratic candidates in the general county-wide election, and none of these four candidates was an incumbent at the time of this election. The Republican Congressman representing Sunrise County endorsed Mr. Dewey, but the Republican Congressman representing Mountain County refrained from endorsing Mr. Landon. Mr. Dewey won his election, but Mr. Landon lost his election. Clearly, the endorsement positions of the respective Congressmen were the deciding factors in these elections.

In evaluating the argument, it would be most useful to know which of the following?

(A) How these two counties have voted in US Congressional and US Presidential elections over the past decade

(B) What stands Mr. Landon and Mr. Dewey took on issues considered most important by registered Democrat voters

(C) How well Congressmen, involved primarily in national politics, are informed of the details of local politics within a single county.

(D) How typical it has been throughout the state, in the past decade, for a Congressman to endorse a county supervisor candidate running in his Congressional district.

(E) How many voters in each of these two counties were aware of their respective Congressman's endorsement positions.

­Between 2000 and 2010, the number of bass in the Mississippi River and its tributaries experienced a catastrophic decline. There is little evidence that pollution or disease was the cause, so it is likely that there was an increase in the number of bass killed by other means. Typically, recreational fishermen in the region prefer to pursue several varieties of river trout, but a state law passed in 2001 banned the catching of trout in the area. Thus, it is likely that recreational fishing was the immediate cause of the decline of the bass population.

Which of the following, if true, most strengthens the argument?

A. The number of Over crayfish, one of the primary sources of nutrition for bass, has quadrupled since the bass population collapsed.

B. Bass prey upon trout and compete for many of the same food sources.

C. The most significant concentrations of remaining bass are in areas of the river where fishing is prohibited.

D. Recreational fishing is less popular now than it was in 2000.

E. Recreational fishing has caused a decline in the populations of several species of fish in other habitats.

­Company spokesperson: The plan to include fewer varieties of meat in Brand X dog food is doomed to failure. It will certainly cause fewer consumers to buy Brand X dog food.

Sales analyst: Actually, marketing studies show that there is no correlation between the number of varieties of meat in a dog food and sales of that dog food.

Which of the following is the most serious criticism of the sales analyst's argument?

(A) The sales analyst does not refer to any specific statistics.

(B) The sales analyst does not specifically refer to Brand X dog food.

(C) The sales analyst's argument is based on outmoded ideas of causality.

(D) The sales analyst refers to how many varieties of meat are in a dog food rather than to the decrease in the number of varieties of meat in the dog food.

(E) The sales analyst presents her evidence in a manner designed to disprove any relationship between ingredients and dog food sales.
