1. Downtown Villieu was once a flourishingbusiness district, but most Villieu-area businesses are now located only in thesuburbs. The office buildings downtownlack the modern amenities most business operators demand today. To lure more businesses downtown, Villieuofficials plan to have several modern office buildings constructed and to offerreduced local tax rates to any business that leases space in a new downtownbuilding
Which of the following, if true, most threatensthe plan's likelihood of success?
--PREP07 CR2 NO.2
Key:
The local tax rates in Villieu's suburbs aresignificantly lower than downtown Villieu's proposed rate for businesses thatlease space in the new office buildings.
2. United Lumberwill use trees from its forests for two products. The tree trunks will be used for lumber andthe branches converted into wood chips to make fiberboard. The cost of this conversion would be the samewhether done at the logging site, where the trees are debranched, or atUnited's factory. However, wood chipsoccupy less than half the volume of the branches from which they are made.
The information given, if accurate, most stronglysupports which of the following?
--PREP07 CR2 NO.7
Key: Transportationcosts from the logging site to the factory that are determined by volume ofcargo would be lower if the conversion into chips is done at the logging siterather than at the factory.
3. Microscopicplants called algae grow inside the top layer of sea ice in the Antarctic ifenough sunlight reaches that layer of ice and enough seawater, which containsnutrients, reaches that layer after splashing onto the surface. Even though moderate snow cover reduces thesunlight that filters into the top layer, sea ice with moderate snow covertypically contains even more algae in the top layer than does sea ice with lesssnow cover.
Which of the following, if true, most helps toexplain the apparent discrepancy?
Key: As the weight of accumulated snow forces icelower in the water, more seawater splashes onto the surface and seeps throughthe snow.
4. Radio stationswith radio data system (RDS) technology broadcast special program informationthat only radios with an RDS feature can receive. Between 1994 and 1996, the number of RDSradio stations in Verdland increased from 250 to 600. However, since the number of RDS-equippedradios in Verdland was about the same in 1996 as in 1994, the number ofVerdlanders receiving the special program information probably did not increasesignificantly.
Which of the following is an assumption on whichthe argument depends?
Key: Few if any ofthe RDS radio stations that began broadcasting in Verdland after 1994 broadcastto people with RDS-equipped radios living in areas not previously reached byRDS stations.
5. The followingappeared in a memorandum from a company’s marketing department:
“Since our company started manufacturing andmarketing a deluxe air filter six months ago, sales of our economy filter—andcompany profits have decreased significantly. The deluxe air filter sells for50 percent more than the economy filter, but the economy filter lasts for onlyone month while the deluxe filter can be used for two months before it must bereplaced. To increase repeat sales of our economy filter and maximize profits,we should discontinue the deluxe air filter and concentrate all our advertisingefforts on the economy filter.”
Discuss how well reasoned . . . etc.
