  CORRECT TEXT

  

  In order to better control traffic at a certain busy intersection, a study was conducted to determine how many vehicles passed through the intersection during various times of day and what trajectories they took. For each possible trajectory (combination of direction from which a vehicle entered the intersection and direction to which it exited the Intersection), the graph shows the number of vehicles passing through the intersection during a certain hour.

  Explanation/Reference:

  Members of many primate species approach an opponent shortly after conflict and initiate behaviors such as embracing, grooming, or huddling--a phenomenon researchers call postconflict reconciliation. Existing research, however, suffers from several shortcomings. The variability between groups of the same species is rarely addressed; the majority of studies investigate only a small fraction of the pairings that exist in a given group; and almost all reports are restricted to animals in captivity. In an attempt to address some of these shortcomings, Sommer et al. recentfy conducted a study of postconflict reconciliation in wild Hanuman langurs, a species of colobine monkey. They observed rates of postconflict reconciliation much lower than would be expected based on previous research, and found that over 80 percent of all pairings exhibited no postconflict affinity whatsoever. The rarity of friendly postconflict reunion in wild langurs draws attention to the possibility that conflicts are modulated through avoidance. The option of temporarily avoiding contact with opponents is not easily available to captive primates, and certainly not to the extent present in the wild. Still, studies of postconflict behavior of primates in captivity remain valuable: above all, they demonstrate the flexibility of nonhuman primates in various environments. It is likely, however, that the reported frequency of reconciliation among primates is artificially inflated by the conditions of captivity.

• Question 26:

  Plague bacilli, the microorganisms that cause bubonic plague, are typically carried from rodents to humans by fleas. Although the bubonic plague epidemic that devastated Europe in the Middle Ages probably originated with certain species of plague-infected rodents from central Asia, the nomadic peoples of central Asia never contracted plague.

  Therefore, since they undoubtedly had some contact with infected rodents, it is likely that these central Asian peoples had physiological immunity against plague bacilli.

  Which of the following, if true, most seriously weakens the argument?

  A. Unlike flea-bearing rodents, which can actually contract bubonic plague, the fleas themselves are merely carriers of the disease.
  B. Certain types of plague can pass directly from one human being to another, without flea or rodent intermediaries.
  C. The plague-infected rodent species that were common in central Asia did not spread to Europe during the Middle Ages.
  D. Plague bacilli were spread from central Asia to Europe by rats inadvertently transported along with tradable goods.
  E. The smell of horses, which were a central feature of life among the nomadic peoples of central Asia, is repellent to the fleas that live on rodents.
  E. The smell of horses, which were a central feature of life among the nomadic peoples of central Asia, is repellent to the fleas that live on rodents.

• Question 27:

  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.

  According to the information provided, which of the following attributes is an advantage of HFC network architecture as compared with FTTH architecture?

  A. Lower new cable deployment costs
  B. Lower maintenance expenses
  C. Greater longevity of coaxial cable
  D. 95% lower internal equipment deployment costs
  E. 90% lower customer installation costs
  C. Greater longevity of coaxial cable

• Question 28:

  A company executive wants to divide the company's n departments into a number of new divisions. How many departments does the company have?

  (1)

  If each new division is to have 5 departments, 2 departments will be left over.

  (2)

  If each new division is to have 6 departments, 3 departments vrfl be left over.

  A. Statement (1) ALONE is sufficient but statement (2) alone Is not sufficient.
  B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
  C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE Is sufficient.
  D. EACH statement ALONE Is sufficient.
  E. Statements (1) and (2) TOGETHER are NOT sufficient.
  E. Statements (1) and (2) TOGETHER are NOT sufficient.

• Question 29:

  Intuition guides people in making Judgments by using learned associations that automatically surface as feelings. As people gain experience in a field, they learn to associate the defining characteristics of phenomena with particular feelings and many of their Judgments can become automatic. For example, rather than going step-by-step through a decision tree, experienced car mechanics will often, after a quick look and listen, intuitively identify the problem.

  Which of the following statements is most strongly implied by the Information above?

  A. An experienced car mechanic does not need to deliberate about most judgments related to that field.
  B. Judgments made on the basis of intuition are rarely wrong.
  C. Most quick Judgments are made on the basis of intuition.
  D. An experienced car mechanic will often be guided by feelings when diagnosing problems with cars.
  E. Judgments made on the basis of a decision tree are less likely to be correct than those made on the basis of intuition.
  C. Most quick Judgments are made on the basis of intuition.

• Question 30:

  The passage mentions "high-frequency changes in inventory" (see bolded text) in order to

  A. explain how rapidly the process of inventory change can be effected
  B. isolate the causal factors that contribute to the changes in production that have been observed
  C. show how the concept of inventory is identical to the concept of buffer stock
  D. identify a kind of event that can help determine whether producers actually use inventories in the way described
  E. demonstrate that when changes in inventory are fast enough, efficient smoothing of production is achieved
  D. identify a kind of event that can help determine whether producers actually use inventories in the way described

  ---

  Explanation/Reference:

  According to the production-smoothing buffer stock model, inventories of a firm's products allow it to supply unexpected demand without having to adjust output immediately. When costs per additional unit produced are increasing, using inventory to smooth production is efficient as long as the savings from not adjusting production exceed the cost of holding inventory. Inventory acts as a buffer stock, absorbing increases or decreases in demand while production remains relatively steady. If firms are smoothing production, then sales should vary more than production. If inventories are used as a buffer stock, then high-frequency changes in inventory should be in the opposite direction to sales. Empirical research using aggregate data does not confirm this expectation, however; production varies more than sales, and changes in inventory and sales tend to vary in the same direction. Thus either the production-smoothing buffer stock model is incorrect, or other factors ere preventing empirical confirmation of the smoothing effect. Most of the research that finds contradictions of production smoothing uses seasonally adjusted aggregate data concerning inventory and sales. It is possible that firms actually do use inventory to smooth production, but the research has failed to detect signs of this activity because the data are too highly aggregated over many firms. But even research at the level of individual companies has failed to confirm the model.
