GWD7-Q21:

Which of the following most logically completes the passage?

Each species of moth has an optimal body temperature for effective flight, and when air temperatures fall much below that temperature, the moths typically have to remain inactive on vegetation for extended periods, leaving them highly vulnerable to predators.  In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why ______.

A.      large moths are generally able to maneuver better in flight than smaller moths

B.       large moths are proportionally much more common in warm climates than in cool climates

C.      small moths are more likely than large moths to be effectively camouflaged while on vegetation

D.      large moths typically have wings that are larger in proportion to their body size than smaller moths do

E.  most predators of moths prey not only on several different species of moth but also on various species of other insects

GWD7-Q30:

Printwell’s Ink Jet Division manufactures ink-jet printers and the ink cartridges they use.  Sales of its ink-jet printers have increased.  Monthly revenues from those sales, however, have not increased, because competition has forced Printwell to cut the prices of its printers.  Unfortunately, Printwell has been unable to bring down the cost of manufacturing a printer.  Thus, despite the increase in printer sales, the Ink Jet Division must be providing the company with much smaller than it used to.

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

A.      Ink-jet printers in regular use frequently need new ink cartridges, and Printwell’s printers only accept Printwell’s ink cartridges.

B.       Unlike some competing companies, Printwell sells all of its printers through retailers, and these retailers’ costs account for a sizable proportion of the printers’ ultimate retail price.

C.      Some printer manufacturers have been forced to reduce the sale price of their ink-jet printers even more than Printwell has.

D.      In the past year, no competing manufacturer of ink-jet printers has had as great an increase in unit sales of printers as Printwell has.

In the past year, sales of Printwell’s ink-jet printers have increased more than sales of any other type of printer made by Printwell.

Magazine Publisher:  Our magazine does not have a liberal bias.  It is true that when a book review we had commissioned last year turned out to express distinctly conservative views, we did not publish it until we had also obtained a second review that took a strongly liberal position.  Clearly, however, our actions demonstrate not a bias in favor of liberal views but rather a commitment to a balanced presentation of diverse opinions.

Determining which of the following would be most useful in evaluating the cogency of the magazine publisher’s response?

A.      Whether any other magazines in which the book was reviewed carried more than one review of the book

B.       Whether the magazine publishes unsolicited book reviews as well as those that it has commissioned

C.      Whether in the event that a first review commissioned by the magazine takes a clearly liberal position the magazine would make any efforts to obtain further reviews

D.      Whether the book that was the subject of the two reviews was itself written from a clearly conservative or a clearly liberal point of view

Whether most of the readers of the magazine regularly read the book reviews that the magazine publishes
