• Question 187:

  Despite the fact that the seeds of certain tropical trees fall mostly around the parent tree, the seeds that land farther from the parent trees of these species have the greatest chance of germinating.

  Which of the following, If true, would most help explain the effect described above?

  A. Tree sprouts from seeds must compete for moisture and nutrients with some of the plant life in their immediate vicinity.

  B. Some tropical trees have winged seeds that tend to prevent them landing beside the parent trees.

  C. Certain tropical tree species are preferentially colonized by some types of mammals.

  D. Soil microbes that prey on seeds and other biological material from trees of the tropical species in question tend to be densest near those trees.

  E. Some plants emit chemicals that are harmful to nearby seeds of other species.

• Question 188:

  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.

  The primary purpose of the passage is to

  A. explain the way in which a particular aspect of organizational culture affects employees' performance

  B. explain why new product development confers less advantage on companies today than it did in the past

  C. argue that a particular strategy for enhancing a company's position against competitors may prove unsuccessful

  D. argue that a company's organizational culture may be more important than its competitive strategy in ensuring financial success

  E. suggest a way in which companies can increase their profits without developing new products
