3. Modern navigation systems, which are found in mostof today’s commercial aircraft, are made withlow-power circuitry, which is more susceptible tointerference than the vacuum-tube circuitry found inolder planes. During landing, navigation systemsreceive radio signals from the airport to guide theplane to the runway. Recently, one plane withlow-power circuitry veered off course during landing,its dials dimming, when a passenger turned on alaptop computer. Clearly, modern aircraft navigationsystems are being put at risk by the electronicdevices that passengers carry on board, such ascassette players and laptop computers.

Which one of the following, if true, LEASTstrengthens the argument above?

(A) After the laptop computer was turned off, theplane regained course and its navigation

instruments and dials returned to normal.

(B) When in use all electronic devices emitelectromagnetic radiation, which is known to

interfere with circuitry.

(C) No problems with navigational equipment orinstrument dials have been reported on

flights with no passenger-owned electronicdevices on board.

(D) Significant electromagnetic radiation fromportable electronic devices can travel up to

eight meters, and some passenger seats onmodern aircraft are located within four meters

of the navigation systems.

(E) Planes were first equipped with low-powercircuitry at about the same time portable

electronic devices became popular.

Outsourcing is the practice of obtaining from an independent supplier a product or service that a company has previously provided for itself.  Vernon, Inc., a small manufacturing company that has in recent years experienced a decline in its profits, plans to boost its profits by outsourcing those parts of its business that independent suppliers can provide at lower cost than Vernon can itself.



Which of the following, if true, most strongly supports the prediction that Vernon's plan will achieve its goal?



(A) Among the parts of its business that Vernon does not plan to outsource are some that require standards of accuracy too high for most independent suppliers to provide at lower cost than Vernon can.

(B) Vernon itself acts as an independent supplier of specialized hardware items to certain manufacturers that formerly made those items themselves.

(C) Relatively few manufacturers that start as independent suppliers have been able to expand their business and become direct competitors of the companies they once supplied.

(D) Vernon plans to select the independent suppliers it will use on the basis of submitted bids.

(E) Attending to certain tasks that Vernon performs relatively inefficiently has taken up much of the time and effort of top managers whose time would have been better spent attending to Vernon's core business.

As part of major renovations to Flowertown's Main Street train station, consultants to the train company proposed moving the station's entrance from its current valuable Main Street location to a low-rent adjoining side street and then leasing the high-rent entrance space to retail businesses.  In that way, the train company could easily pay for those and all other proposed renovations without negative impact on its tight budget.



Which of the following, if true, would most strongly support the consultants' proposal?



(A) More train commuters are employed in businesses located on Main Street than in businesses located on the adjoining side street.

(B) A reliable survey of Flowertown's commuters showed that virtually none of them would use the train any less frequently if the station's entrance were moved.

(C) The high-rent block of Flowertown's Main Street includes several buildings whose owners currently seek to replace long-standing tenants lost in recent months.

(D) If the station's entrance were moved, the train company would need to begin costly renovations to its Main Street entrance space.

(E) Ridership on Flowertown trains declined only slightly from 1970 to 1985 while other train companies lost large numbers of commuters.

Paint on a new airliner is usually applied in two stages:  first, a coat of primer, and then a top coat.  A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat.  Using the new process instead of the old process increases the price of a new aircraft considerably.



Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?



(A) Although most new airliners are still painted using the old process, aircraft manufacturers now offer a purchaser of any new airliner the option of having it painted using the new process instead.

(B) A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.

(C) A single layer of the new coating provides the aluminum skin of the airliner with less protection against corrosion than does a layer of primer of the usual thickness.

(D) Unlike the old process, the new process was originally invented for use on spacecraft, which are subject to extremes of temperature to which airliners are never exposed.

(E) Because the new coating has a viscosity similar to that of a traditional top coat, aircraft manufacturers can apply it using the same equipment as is used for a traditional top coat.

Archaeologists in Michigan have excavated a Native American camp near Dumaw Creek.  Radiocarbon dating of animal bones found at the site indicates that the camp dates from some time between 1605 and 1755.  However, the camp probably dates to no later than 1630, since no European trade goods were found at the site, and European traders were active in the region from the 1620's onward.



Which of the following, if true, most strengthens the argument?

(A) Due to trade among Native Americans, some European trade goods would have reached the area before the European traders themselves did.

(B) At all camps in the region that have been reliably dated to the late 1620's, remains of European trade goods have been found.

(C) The first European trade goods to reach the area would have been considered especially valuable and preserved as much as possible from loss or destruction.

(D) The first European traders in the area followed soon after the first European explorers.

(E) The site is that of a temporary camp that would have been used seasonally for a few years and then abandoned.

Male bowerbirds construct elaborately decorated nests, or bowers.  Basing their judgment on the fact that different local populations of bowerbirds of the same species build bowers that exhibit different building and decorative styles, researchers have concluded that the bowerbirds' building styles are a culturally acquired, rather than a genetically transmitted, trait.



Which of the following, if true, would most strengthen the conclusion drawn by the researchers?



(A) There are more common characteristics than there are differences among the bowerbuilding styles of the local bowerbird population that has been studied most extensively.

(B) Young male bowerbirds are inept at bowerbuilding and apparently spend years watching their elders before becoming accomplished in the local bower style.

(C) The bowers of one species of bowerbird lack the towers and ornamentation characteristic of the bowers of most other species of bowerbird.

(D) Bowerbirds are found only in New Guinea and Australia, where local populations of the birds apparently seldom have contact with one another.

(E) It is well known that the song dialects of some songbirds are learned rather than transmitted genetically.

Answer choice (A): This answer choice strengthens the argument by showing that when the cause is absent, the effect does not occur (Type C). Once the laptop was turned off, the cause disappeared, and according to the author’s beliefs, the effect should then disappear as well.
Answer choice (B): This answer strengthens the argument by showing that the data used to make the conclusion is accurate (Type E). By stating that all electronic devices emit radiation, the answer choice closes a hole in the argument.
Answer choice (C): This answer choice strengthens the argument by showing that when the cause is absent, the effect does not occur (Type C).
Answer choice (D): This answer strengthens the argument by showing that the data used to make the conclusion is accurate (Type E). By showing that radiation can travel far enough to reach the cockpit, the cause is confirmed as possible.
Answer choice (E): This is the correct answer. The fact that the circuitry and electronic devices became popular at the same time does not offer any supporting evidence to the contention that the electronic devices cause the interference with the low power circuitry. This answer has no effect on the argument and is therefore correct.
