A study examining ninety large cities found that in those with more kilometers of bicycle paths and roadway bicycle lanes per capita, higher percentages of the population commute to work by bicycle. For this reason the study concluded that adding bicycle paths and lanes is an effective way to encourage commuters to bicycle rather than drive.

Which of the following, if true, would most weaken the reasoning in the study'

Daniel: Historically, railroads substantially altered the course of the United States economy, enabling the country to enjoy unprecedented growth in the nineteenth century.

Robert: It's true that growth required cheap inland transportation, which railroads provided. But with government support similar to the massive land grants that subsidized rapid railroad expansion, canals and roads could have had the same effect.

Which of the following is most likely a point that Robert believes is at issue between Daniel and himself?

Company J is reducing its information technology (IT) staff by one-half but is requiring the IT department to continue meeting all the IT needs of the employees. IT managers plan to accomplish this by investing in a computer program that relieves employees of the need to remember their passwords for logging in to Company J's numerous office systems. Half of the IT staffs time is currently spent on password-related assistance, so once the program is implemented, Company J can make the required staff cuts.

Which of the following would it be most useful to know in order to evaluate whether the IT managers' plan is feasible as a means to continue meeting the IT needs of the employees?

The Hupa's overwhelming interest in wealth and social position allies them with the North Pacific tribes, but the Hupa thought that the distribution or destruction of property during a potlatch, as those tributes did, was a preposterous idea and beyond their comprehension.

It is known from cave paintings and other evidence that the hunting people occupying the Bax Cave area in Country X tens of thousands of years ago repeatedly set fire to

the surrounding area. Archaeologists hypothesize that because the fires caused later plant growth on the land, the hunters set the fires in order to attract herbivorous prey

species. Such actions, they claim, are evidence for the mental capacity to delay gratification for weeks, months, or even years.

Which of the following would it be most useful to determine in evaluating the archaeologists’ claim?

Because of the positive correlation across animal species between body size and home range size, researchers suspected that body size of female mallards (a species of duck) may influence their home range size. The researchers also reasoned that younger females may be forced into less suitable habitats by older females competing with them for optimal areas, with the younger females compensating by having larger home ranges. However, their research supported neither suspicion. The failure to detect variation of range size according to body size may be due to other, undetermined mallard attributes (for example, body condition) that may have been a significant factor affecting home range size. The fact that most yearling females can breed may help to explain why the expected age effect was not confirmed, since home range size may be affected by breeding capability.

The researchers did find, however, that home range size of females was Inversely related to the percentage of the study area composed of seasonal or semipermanent wetlands. This may have been because of reduced competition for breeding space within the species when more of the wetlands were present. They also found home range size to decrease somewhat as the percentage of wood-shrub habitat increased, suggesting that reduction in visual contact among mallard pairs may reduce interaction and thus reduce competition among breeding pairs.

The author's purpose in making the statement that most yearling female mallards are able to breed is most likely in order to

Until the Apollo astronauts brought samples of lunar material to Earth during 196£-72, scientists believed that the Moon's surface was largely undisturbed, given its dry, airless environment. Examination of the samples has shown otherwise. Micrometeorites, many smaller than a pencil point, constantly rain onto the Moon at up to 100,000 kilometers per hour, chipping materials or forming microscopic craters. Some melt the soil and vaporize and recondense as glassy coats on other specks of dust. Impacts weld debris into lumps of heterogeneous matter called "agglutinates." Complicated interactions with solar particle streams convert iron into myriads of microscopic iron grains. The regdith—pebbles, sand, and dust-from these erosion processes blankets the Moon. Much of the top layer consists of a complex abrasive dust of microscopic glass shards that can grind machinery and sealing devices and damage human lungs.

The Apollo specimens held by the United States are doled out in ultra-small samples to scientists who demonstrate that nothing else will suffice for high-value experiments. Renewed interest In lunar exploration in the late 1980s meant that materials designed to simulate lunar regolith—simulants—were needed for research to develop schemes for lunar building and procedures for extracting elements such as oxygen found abundantly in regolith. That led to the development of JSC-1 in 1993, made of volcanic cinder cone from a quarry in Arizona in the U.S. The more than 22 metric tons made was in high demand. Efforts are now afoot to manufacture 16 metric tons of JSC-1 A, with 1 ton of fine grains, 14 tons of moderately fine, and 1 ton of coarse.

Acme Software plans to release a partial version of its X software, which will be the same as the full version except that some features will be disabled and K wM cost half as much. Company executives believe marketing both products at once will substantially increase profits. They think some customers who would not have bought the full version will buy the partial version. Profits from seeing to those customers, they believe, will exceed the money lost by selling the partial version to customers who would have paid more for the full version if it were the only one avalabie.

Which of the following would, if true, provide the strongest reason to doubt that Acme Software's plan will result in higher profits?

West River Glen is deciding which network architecture should replace its old copper telephone lines. The town will replace 300 miles of Outside Plant (OSP) cable that will serve approximately 2,500 homes.

The first option is to install a Fiber to the Home (FTTH) system architecture that uses fiber-optic cable to transmit signals from the source to each home. The advantages of this architecture include greater bandwidth capabilities, less signal loss, and slightly lower new-cable deployment costs than the second option, Hybrid Fiber-Coax (HFC).

An HFC network integrates fiber-optic cables and devices with coaxial cables.

This will cost the town substantially less money for internal equipment and for customer installations. However, the coaxial cable does not last as long as fiberoptic cable and will thus need to be replaced more frequently, resulting in higher long-term maintenance expenses.

The town believes that either the FTTH or HFC architectures will be capable of serving the communities' data and television needs for the next 30 years.

The answer to which one of the following can be determined by using the information in the passage and tables?

Sales promotions can involve selling a product at a relatively low price or selling the product with a free (or seemingly free) unit of the product, as in "buy one, get one free" campaigns. Research shows that immediately following month-long sales promotions, a postpromotion dip may occur, i.e., sales for the following calendar month may be less than sales for the calendar month preceding the sales promotion.

To increase sales, Storex, a department store, held month-long sales campaigns to promote four of its products. A sales promotion was considered successful if unit sales of the product were at least 10% higher in each of the 2 calendar months immediately following the promotion than In the month preceding it.

Experts have offered explanations for postpromotion dip:

• Explanation I: Many consumers stockpile the product at relatively low cost during the sales promotion.

• Explanation II: "Buy one, get one free" promotions cause some consumers to undervalue the product, making them less likely to buy it following the sales promotion.

• Explanation HI: Many consumers who missed a "buy one, get one free" opportunity may, as a result, develop so-called inaction inertia, i.e., become less likely to buy the product at either the regular or even at a discount price than if the sales promotion had not occurred.

Which one of the following is most strongly supported by the sales data, given the other Information provided?

Many companies today are making new product development a central element of their competitive strategy. Because the potential benefits of successful product innovation are great—prolonged growth, superior financial returns, and strong investor interest-many companies offer employees incentives such as promotions and bonuses for developing new products, incentives not offered for innovations in other areas of the business, firms' priorities can also be shaped by their measurement systems, since these systems can directly measure returns from new products more immediately than they can measure returns from investments in such areas as organizational restructuring or innovations in marketing.

But the organizational culture of such companies can hurt them in the marketplace because a narrow focus on product development can ultimately detract from a firm's performance. For instance, a company's ability to profit from new products can be severely hampered if it has neglected other functions and business processes. If a company develops a superior new product but is unable to distribute and promote t rapidly, competitors with better distribution systems may copy the product and introduce It into the market before the innovator can profit from its innovation. In contrast, effective distribution, marketing, and accounting systems-that is, strong overall business systems -can act as entry barriers, deterring would-be competitors from entering a particular
