• Question 381:

  HOTSPOT

  Today a certain cinema multiplex has exactly two showings (an early showing and a late showing) for each of five films (Rims A, B, C, D, and E). All of these showings occur after noon, and each showing consists of the film only, with no previews, announcements, or advertisements. The following gives the duration of each film and the start time for each showing:

  1. Film A (90 minutes); 3:45 and 5:30

  2. Film B (100 minutes); 1:30 and 7:15

  3. Film C (105 minutes); 2:00 and 6:00

  4. Film D (115 minutes); 5:00 and 8:00

  5. Film E (125 minutes); 12:15 and 7:00

  Statement: The early showing of Rim ---------1 overlaps with at least part of both showings of Film ---------- 2.

  Select for / and for 2 the options that complete the statement so that It Is accurate of the showings listed in the Information provided. Make only two selections, one in each column.

  Explanation/Reference:

  Soil salinization--the process by which soil acquires excess soluble salt, adversely affecting pasture or crop growth--is regarded as Australia's most serious environmental problem. Cope, whose 1958 investigation is considered the earliest survey of salt-affected areas in Victoria, hypothesized that surplus rainwater mobilized soluble salt stored in the permeable layer of soil, causing it to accumulate above an impermeable layer and then discharge downslope or onto a valley floor. In the late 1970s, however, Jenkin identified saline water underground as the main and immediate (though not ultimate) source of the salt, and hypothesized that the spread of salinity resulted from a rise in that groundwater. He attributed the rise to a decrease in coverage by water-absorbing trees and other vegetation at some ill-defined point in Australia's post-settlement history. However, more-recent research suggests there was no rise in post- settlement groundwater levels. Furthermore, soil salinity probably antedated European settlement: early cartographic evidence indicates that some streams were saline when Europeans arrived. Dahlhaus suggests that salt accumulation resulted from marine incursions several million years ago, when parts of Victoria may have been submerged--as well as from transport of salt from the sea by wind and rain. Dahlhaus also notes that various minerals dissolved in groundwater by weathering may have produced salt.

• Question 385:

  HOTSPOT

  Welleby's Plan The water In the underground water table beneath the town of Welleby is moderately saline-- 20,000millkjrarns of salt per liter of water (mg/L), or roughly half as saline as ocean water. To lower the level of the water table and thus prevent agricultural land from being inundated with salt water, the town plans to pump water from the table at a rate of 450kiloliters per day (kL/day) into a large shallow pond, allowing much of the water to evaporate. The town plans to divert 10percent of the water pumped from the water table to supplement Us supply of drinking water, which Is currently piped In from great distances. Due to the water's supply, the town intends to construct a desalination plant to treat the diverted water for use as drinking water.

  

  Welleby is deciding among the following three desalination methods. Reverse Osmosis (RO): Water Is pushed through a membrane, leaving salts behind. RO systems can handle a large range of water flow rates and use relatively little energy. However, RO membranes are expensive and must be replaced every 2 to 5 years. There is also a possibility that bacteria can grow on the membrane. Introducing tastes and odors Into the desalinated water. Multi-Effect Distillation (MED): Saline water Is heated to produce water vapor, from which is condensed potable fresh water. This process requires large amounts of energy, regardless of the salinity of the source water. It becomes more cost effective as water volumes increase. Electrodialysis (ED): Electricity is used to selectively move salts through a membrane. Consumption of energy Is directly proportional to the salinity of the water to be treated, so with higher salinities the process rapidly becomes more costly than other methods. ED membranes need to be replaced every 7 to 10years.

  HOTSPOT

  A city's chamber of commerce has the following goal for small businesses: revenue should be at least 20% greater than costs. The Venn diagram indicates that x is the number of small businesses that both in Year 1 and in Year 2 met the goal. The diagram also indicates that 53 - x is the number of small businesses that met the goal in Year 1 but not in Year 2, and that 47 - x is the number of small businesses that met the goal in Year 2 but not in Year 1.

• Question 387:

  According to the passage, organizational ecology studies support which of the following statements regarding structurally equivalent organizations?

  A. Organizations that compete intensely within local population boundaries ultimately benefit from the increased competition soured by colocation.
  B. Organizations in industries with intense competition for scarce vital resources experience higher failure rates than do those in which such resources are widely available.
  C. Organizations that share access to scarce raw materials compete with each other less intensely than do those that share access to common labor markets.
  D. Organizations that are situated near each other compete with each other more intensely than do those that are situated in different geographical locations.
  E. Organizations that benefit from advantages such as knowledge spillovers are better able to adapt to market changes than are organizations that benefit from intrinsic advantages such as proximity to consumers.
  D. Organizations that are situated near each other compete with each other more intensely than do those that are situated in different geographical locations.

  Explanation/Reference:

  Organizations that produce similar goods tend to concentrate in the same geographic area (geographic concentration of production). Economic explanations of such industrial agglomeration explicitly emphasize better performance, and implicitly emphasize lower failure rates, as the key processes contributing to this geographic concentration. Sometimes Industries benefit economically from situating themselves in particular locations that offer intrinsic advantages such as access to scarce raw materials or proximity to consumers. In other cases, regardless of the particular location, the colocation of structurally equivalent organizations--those that operate in the same markets--may itself yield advantages such as common labor markets and knowledge spillovers. Sorenson and Audia point out that these explanations Ignore the fact that structurally equivalent organizations also compete with one another for vital resources, and colocation would be expected to increase such competition. Organizational ecology studies support this expectation by showing that organizations apparently compete more intensely within local population boundaries. Sorenson and Audia propose instead that what maintains geographic concentration is entrepreneurial opportunity, which leads to higher founding rates. Dense local concentrations of structurally equivalent organizations increase the pool of potential entrepreneurs in a region. Beginning entrepreneurs need exposure to existing organizations in the industry to acquire knowledge of the business, ties to scarce resources, and self-confidence. The existing geographic concentration of production constrains access to these resources, so that new founding's tend to reinforce geographic concentration.

  The editor of Metathesis, a new academic journal of literature, manages the peer-review of articles submitted for publication. The journal accepts articles focusing on any of three general subject areas:

  comparative literature, modernist literature, and postcolonial literature. When an article is submitted, the editor has the article peer-reviewed by exactly three experts, none of whom authored or coauthored the article. The table (see the Reviewers/Authors tab) consists of all the authors or coauthors who have recently submitted articles and all the experts who currently peer-review or have recently peerreviewed those articles. It also lists the general subject areas for each of the authors and reviewers.

  Each author of each submitted article specializes in the general subject area of the article. Moreover, each recently submitted article was peer-reviewed by experts listed in the table.

  

  Suppose Laprade was the secondary reviewer of a recently submitted article. For each of the following statements, select Keslf the statement must be true, based on this supposition and the information provided. Otherwise, select Ato.
