CR 1

Saltation is a sudden and large mutational change taking place over a single generation of a species and depends on a variety of factors related to the habitat and biology of the species. These factors differ in how they affect different species, meaning they should produce a random pattern of mutational change. Yet, careful paleontological study has shown that saltation occurs in a surprisingly consistent pattern, with many species changing at the same time.

Which of the following, if true, forms the best basis for at least a partial explanation of the patterned saltation revealed by the paleontological study?

A. In geologically recent times, for which paleontological study is impossible, human intervention has changed the pattern of saltation.
B. In certain instances, saltation selectively affects organisms with certain unique, species-specific sets of characteristics.
C. Some species experience saltation because of sudden changes in their food chain.
D. Saltation is sometimes a result of wide-ranging environmental disturbances that affect many different species.
E. Widely dispersed species are the least likely to experience saltation.

As part of an effort to lower operating costs, Daedlus Webhosting Services plans to conduct routine maintenance on its server farm’s cooling system once every fortnight, rather than once every three months – the standard maintenance schedule for such technology. With a more robust maintenance schedule, Daedlus can postpone complete system overhauls, which put the servers out of commission for up to seven months. Moreover, routine maintenance procedures reduce the cooling system’s power consumption by roughly three percent.

The webhosting company’s plan assumes that

A. electricity rates are likely to rise soon and thus, reducing electricity consumption is a high priority
B. cooling system maintenance does not put a server farm out of commission
C. in the long run, fortnightly maintenance of a server farm’s cooling system does not cost much more than a complete system overhaul does
D. Daedlus Webhosting Services has had more severe issues regarding server farm cooling system overhauls and electricity consumption than other webhosting services have
E. conducting routine maintenance on the server farm’s cooling system once a fortnight will give Daedlus Webhosting Services a competitive advantage over other webhosting services

__________________________
CR 1

In an interview to a business daily, a senior manager at Windsor Hotels recently stated that the hotel is mishandled, sharing as proof the hotel’s inability to modify its marketing strategy in response to a recent increase in its number of unoccupied rooms. A senior manager’s negative comments are generally detrimental to the image of the company, but in this case, the negative comments were not justified. It is correct that an increased number of unoccupied rooms at a hotel often indicates that the hotel is losing clients to competitors, but in Windsor’s situation, it does not showcase such a thing. Instead, the increase in the number of unoccupied rooms is completely attributable to the cancellation of two of the city’s biggest events earlier this year.

In the argument given, the two boldfaced portions play which of the following roles?

(A) The first provides evidence to support the conclusion of the argument as a whole; the second is evidence that has been used to support the position opposed by the argument as a whole.
(B) The first provides evidence to support the conclusion of the argument as a whole; the second states that conclusion.
(C) The first and the second each provide evidence against the position opposed by the argument as a whole.
(D) The first states a generalization that underlies the position opposed by the argument as a whole; the second provides evidence to show that the generalization is inapplicable in the case at issue.
(E) The first states a generalization that underlies the position opposed by the argument as a whole; the second clarifies the meaning of a specific phrase as it is used in that generalization.

CR 2

A chemical factory periodically produces toxic phosphates as runoff, which it drains into a small river. This river carries the phosphates to a stretch of grassland, where they are absorbed by wild sunflowers. The phosphate accumulates in various parts of the plant, without harming the plant, and breaks down into non-toxic elements as the plant decays. However, when a certain species of hummingbird feeds off of the phosphate carrying flowers, it dies. Thus, the chemical factory is putting hummingbirds in the region at risk.

To assess the argument, which of the following would be most helpful?

A. Whether fish in the phosphate carrying river are likely to die from the phosphates’ effects
B. Whether the flower of the phosphate carrying sunflower is as toxic as other parts of the sunflower plant
C. Whether the chemical factory produces as much toxic runoff as other chemical factories do
D. Whether the hummingbirds are feeding off of sunflowers growing in the stretch of grassland downstream from the chemical factory
E. Whether any other birds compete with the hummingbirds to feed off of the sunflowers growing near the river
