Adam, Ben, and Clara are hired to weed a garden at a community center. If Adam and Ben, working simultaneously and independently at their respective constant rates, can weed the garden in 6 hours, how long would Adam and Clara, working simultaneously and independently at their respective constant rates, take to weed the garden?

(1) Adam, Ben, and Clara, working simultaneously and independently at their respective constant rates, can weed the garden in 4 hours.
(2) Ben, working alone at his constant rate, would take 50% more time to weed the garden than Adam, working alone at her constant rate, would take.
______________________
a-research-labs-data-archive-increased-by-20-each-year-if-during-th-457595.html

Starting at the beginning of 2007, a research lab’s data archive increased by 20% each year for a whole number of years. If no data was deleted during this period, how many gigabytes of data were in the archive at the end of the period?

(1) By the end of the period, the amount of data in the archive had increased by 44%.
(2) If 360 gigabytes of data had been deleted at the beginning of the final year of the period, the amount of data in the archive at the end of the period would have been 12% less than its actual amount at the end of the period.

____________________
CR 1

The ancient Spartans relied on conquest far more than did citizens of other, similarly sized Greek cities. Historians have hypothesized that it was a paucity of agricultural resources that drove the Spartans to subjugate so much foreign territory. This hypothesis is difficult to confirm directly, as sufficiently detailed records of Spartan agricultural output did not survive the medieval periods. However, careful comparison between the pattern of Sparta’s conquests and climate records kept by nearby civilizations show that the Spartans launched a higher number of military campaigns during years when regional agriculture suffered due to inclement weather. This indicates that there is some merit to the hypothesis.

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

A. The first presents an explanatory hypothesis; the second states the argument’s main conclusion.
B. The first presents an explanatory hypothesis; the second presents evidence in order to support an alternative explanation.
C. The first presents an explanatory hypothesis; the second presents evidence that tends to support this hypothesis.
D. The first describes a position opposed by the argument; the second presents evidence to undermine the support for the opposed position.
E. The first describes a position opposed by the argument; the second states the argument’s main conclusion.

____________________
CR 2

A software has been designed to help nuclear power plants determine the necessity of an emergency shutdown, in the event of a drop in coolant pressure by analyzing the drop and comparing it against a database of 10,000 simulated nuclear coolant failure scenarios. The software is meant to help nuclear power plant workers determine whether a disruption in the plant’s coolant flow is severe enough to lead to a meltdown, necessitating an emergency shutdown.

In order to assess the effectiveness of the software for its stated purpose, it would be most helpful to establish which of the following?

A. Whether the nuclear coolant failure scenario database will receive regular updates of new simulations.
B. Whether nuclear power plant workers routinely misjudge the severity of drops in coolant pressure.
C. Whether a significant number of nuclear safety professionals will vouch for the software.
D. Whether the database also includes simulations of scenarios wherein coolant flow is stable.
E. Whether the use of this software will enable nuclear power plant workers to make sound decisions regarding the necessity of an emergency shutdown, before a meltdown occurs.

______________________
DS 1

A regional express train normally travels from Northgate Station to Lakeside Station by its regular route and has a fixed scheduled travel time for that route. On one day, because of track maintenance, the train traveled from Northgate to Lakeside by a detour route instead. Was the train’s travel time that day more than 2 hours longer than the scheduled travel time?

(1) The train’s average (arithmetic mean) speed on the detour route differed from its average (arithmetic mean) speed on the regular route by no more than 20 kilometers per hour.
(2) The distance the train traveled on the detour route differed from the distance on the regular route by no more than 40 kilometers.
______________________
DS 2

At a science quiz, Team Atlas consisted of Elena, Hugo, and Liam, and Team Nova consisted of Mia, Theo, and Nora. If a team’s score was the average (arithmetic mean) of the three scores earned by its members, what was Team Atlas’s score?

(1) Elena scored 15 points more than Mia, Hugo scored 6 points fewer than Theo, and Liam scored 18 points fewer than Nora.

(2) If Mia had scored 18 points more, Team Nova’s score would have been 20% greater than Team Atlas’s score.

CR 1

The extract of the cacao leaves was considered a miracle cure-all in the 1800s. Doctors believed that a mixture of the extract and wine, if drunk regularly, could kill off parasitic infestations, destroy tumors, and revitalize living tissue.

Which of the following, if true, most strongly indicates that the logic of the belief described above is flawed?

A. To make the cacao leaf extract safer to consume, it could be diluted with alcohol without weakening its desired effects.
B. Since tumors are living cells, the mixture would affect them in the same way that it would affect living tissue.
C. It cannot be presumed that the use of a particular medication is always appropriate.
D. If the suggested treatment were put into effect on a wide scale, healthcare costs would be lower than they are now.
E. Because consuming the cacao leaf extract would alter the consumer’s metabolism, a new diet would have to be designed for them to remain healthy.

________________________
CR 2

The city of Dreaming has a population of 60,000 and only one home insurance provider, Endless Insurance. The city’s welfare department calculated that a homeowner earning the city’s median income of $60,000 a year could afford Endless Insurance’s median-priced home insurance coverage, which costs $7,000. The welfare department based this calculation on a 12 percent annual interest rate and on the assumption that Dreaming’s homeowners could only afford to allocate up to five percent of their respective incomes towards insurance.

Which of the following corrections of a figure mentioned in the above passage, if it were the only necessary correction, would lead to a new calculation indicating that even incomes below the median income would permit homeowners to afford Endless Insurance’s median-priced home insurance coverage?

A. The total population of the city of Dreaming is 57, 000.
B. The annual payment rate on Endless Insurance’s home insurance policies is 10 percent.
C. The median-priced home insurance offered by Endless Insurance costs $8,000.
D. The median income in the city of Dreaming was $55,000.
E. Dreaming’s homeowners can afford to allocate only four percent of their income towards insurance.

A home-goods warehouse inspected a shipment of ceramic mugs for glazing flaws. Of the mugs in the shipment, 70% were blue-glazed, and the rest were not blue-glazed. Of the mugs that were not blue-glazed, 2/5 had a glazing flaw. What percentage of the blue-glazed mugs did not have a glazing flaw?

(1) If one mug is selected at random from the shipment, the probability that it will have a glazing flaw is 0.32.

(2) If one mug with a glazing flaw is selected at random from the shipment, the probability that it will be blue-glazed is 5/8.
