1.Transnational cooperation among corporations is experiencing a modest renaissance among United States firms, even though projects undertaken by two or more corporations under a collaborative agreementare less profitable than projects undertaken by a single corporation. The advantage of transnational cooperation is that such joint international projects may allow United States firms to win foreign contracts that they would not otherwise be able to win.
Which of the following is information provided by the passage?
(A) Transnational cooperation involves projects too bigfor a single corporation to handle. (B) Transnational cooperation results in a pooling of resources leading to high-quality performance.
(C) Transnational cooperation has in the past been both more common and less common than it is now among United States firms.
(D) Joint projects between United States and foreign corporations are not profitable enough to be worth undertaking.
(E) Joint projects between United States and foreign corporations benefit only those who commission the projects.
Key: C
2. The sustained massive use of pesticides in farming has two effects that are especially pernicious. First, it often kills off the pests' natural enemies in the area. Second, it often unintentionally gives rise to insecticide-resistant pests, since those insects that survive a particular insecticide will be the ones most resistant to it, and they are the ones left to breed.
From the passage above, it can be properly inferred that the effectiveness of the sustained massive use of pesticides can be extended by doing which of the following, assuming that each is a realistic possibility?
(A) Using only chemically stable insecticides
(B) Periodically switching the type of insecticide used
(C) Gradually increasing the quantities of pesticides used
(D) Leaving a few fields fallow every year
(E) Breeding higher-yielding varieties of crop plants
Key: B
3. Treatment for hypertension forestalls certain medical expenses by preventing strokes and heart disease. Yet any money so saved amounts to only one-fourth of the expenditures required to treat the hypertensive population. Therefore, there is no economic justification for preventive treatment for hypertension.
Which of the following, if true, is most damaging to the conclusion above?
(A) The many fatal strokes and heart attacks resulting from untreated hypertension cause insignificant medical expenditures but largeeconomic losses of other sorts.
(B) The cost, per patient, of preventive treatment for hypertension would remain constant even if such treatment were instituted on alarge scale.
(C) In matters of health care, economic considerations should ideally not be dominant.
(D) Effective prevention presupposes early diagnosis, and programs to ensure early diagnosis are costly.
(E) The net savings in medical resources achieved by some preventive health measures are smaller than the net losses attributable tocertain other measures of this kind.
Key: A
4. Guitar strings often go "dead"--become less responsive and bright in tone--after a few weeks of intense use. A researcher whose son is a classical guitar is hypothesized that dirt and oil, rather than changes in the material propertiesof the string, were responsible.
Which of the following investigations is most likely to yield significant information that would help to evaluate the researcher's hypothesis?
(A) Determining if a metal alloy is used to make the strings used by classical guitarists
(B) Determining whether classical guitarists make their strings go dead faster than do folk guitarists
(C) Determining whether identical lengths of string, of the same gauge, go dead at different rates when strung on various brands of guitars
(D) Determining whether a dead string and a new string produce different qualities of sound
(E) Determining whether smearing various substances on new guitar strings causes them to go dead
Key: E
AA:
The following appeared as part of a business plan by the CapitalIdea Investment firm.
“Currently more and more books are becoming available in electronicform — either free of charge on the Internet or for a very low price per bookon CD-ROM.* People who would not pay bookstore prices will now have access towhatever book they want from their home or work computers. Consequently, literaryclassics are likely to be read more widely than ever before: 72 percent ofthose responding to a recent online survey said they would read books inelectronic form, and 81 percent said they believed that reading classic workswas important. Given this newly developing market, we should invest inE-Classics, a new company that sells electronic versions of literary classics.”
