The Quasi JX is a new car model. Under ideal driving conditions, the Quasi JX's fuel economy is E kilometers per liter(E km/l) when its driving speed is constant at S kilometers per hour (S km/h).

In terms of the variables S and E, select the expression that represents the number of liters of fuel used in 1 hour of driving under ideal driving conditions at a constant speed S, and select the expression that represents the number of liters of fuel used in a 60 km drive under Ideal driving conditions at a constant speed S. Make only two selections, one in each column.

The following excerpt from a fictitious science news report discusses a fictitious type of location called a morefa.

For zoologists studying the behavior of certain species of birds, the critical importance of observing the birds in those species' morefa during the annual breeding season is obvious. Such observation allows researchers to study not only the courtship displays of many different individuals within a species, but also the species' social hierarchy. Moreover, since some species repeatedly return to the same morefa, researchers can study changes in group dynamics from year to year. The value of observing a morefa when the birds are not present, however—such as prior to their arrival or after they have abandoned the area to establish their nests—is only now becoming apparent.

Based on the definition of the imaginary word morefa that can be inferred from the previous paragraph, which of the following activities of a bird species must happen in a location for that location to be the species' morefa, and which must NOT happen in a location for that location to be the species' morefa? Make only two selections, one in each column.

and R represents the number of students per faculty member in Fall 1999. The percent change in a quantity X is calculated using the formula

Select the expression that represents the number of faculty in Fall 1999, and select the expression that represents the number of students per faculty member in Spring 2004. Make only two selections, one in each column.

A literature department at a small university in an English-speaking country is organizing a two-day festival in which it will highlight the works of ten writers who have been the subjects of recent scholarly work by the faculty. Five writers will be featured each day. To reflect the department's strengths, the majority of writers scheduled for one of the days will be writers whose primary writing language is not English. On the other day of the festival, at least four of the writers will be women. Neither day should have more than two writers from the same country. Departmental members have already agreed on a schedule for eight of the writers. That schedule showing names, along with each writer's primary writing language and country of origin, is shown.

• Day 1:

Achebe (male, English, Nigeria) Weil (female, French, France) Gavalda (female, French, France) Barrett Browning (female, English, UK)

• Day 2:

Rowling (female, English, UK) Austen (female, English, UK) Ocantos (male, Spanish, Argentina) Lu Xun (male, Chinese, China)

Select a writer who could be added to the schedule for either day. Then select a writer who could be added to the schedule for neither day. Make only two selections, one in each column.

An architect is planning to incorporate several stone spheres of different sizes into the landscaping of a public park, and workers who will be applying a finish to the exterior of the spheres need to know the surface area of each sphere. The finishing process costs $92 per square meter. The surface area of a sphere is equal to 4π~$r^2$~  where r is the radius of the sphere.

In the table, select the value that is closest to the cost of finishing a sphere with a 5.50-meter circumference as well as the cost of finishing a sphere with a 7.85-meter circumference. Make only two selections, one in each column.

Swamp sparrows live in a variety of wetland habitats. Unlike most swamp sparrows, which live in freshwater habitats, the coastal- plain subspecies lives in tidal wetlands, where freshwater and seawater mix and the mud is gray rather than brown. Coastal-plain swamp sparrows differ from all other populations of swamp sparrows in having plumage that is gray brown rather than rusty brown. DNA analysis indicates several important genetic differences between swamp sparrows that inhabit tidal marshes and other subspecies of swamp sparrows. Therefore there must have been genetic - selection pressure on swamp sparrows in tidal marshes to become darker and grayer.

Loan X has a principal of $10,000x and a yearly simple interest rate of 4%. Loan Y has a principal of $10,000y and a yearly simple interest rate of 8%. Loans X and Y will be consolidated to form Loan Z with a principal of $(10,000x + 10,000y) and a yearly simple interest rate of r%, where r=~$\frac{4x+8y}{x+y}$~ In the table, select a value for x and a value for y corresponding to a yearly simple interest rate of 5% for the consolidated loan. Make only two selections, one in each column.

Advice from a computer security expert, on passwords used for accessing online accounts:

Computer users should use a different password for each online account. They should also use strong passwords, which are hard for hackers to decipher. However, strong passwords are difficult to remember, and this is especially the case for users who have multiple online accounts.

Fortunately, software is available for little or no cost that can store and encrypt a user's passwords: the user need only remember one password to access the rest. For users willing to take the time to install the software on a computer and enter all the required data, such software provides one way to comply with security expert's advice. Some versions of the software can even be copied to a portable device, such as a USB drive, whereby a user can access passwords from any compatible computer.

For a computer user with multiple accounts who would not otherwise use a different strong password on every account, the expert's advice amounts to suggesting that users make certain sacrifices in order to make certain gains. Indicate by appropriate selections in the first and second column which of the items in the third column would describe a sacrifice for this user and which would be a gain. Make only two selections, one in each column.

In recent years, bee populations have been dropping rapidly, partly due to a phenomenon known as Colony Collapse Disorder. Scientists also fear pesticides are destroying bee populations, but it is not clear how they are causing damage.

In the first of the Science studies, a University of Stirling team exposed developing colonies of bumblebees to low levels of a chemical pesticide called imidacloprid, and then placed the colonies in an enclosed field site where the bees could fly around collecting pollen under natural conditions for six weeks. A control group was not exposed to imidacloprid.

At the beginning and end of the experiment, the researchers weighed each of the bumblebee nests - which included the bees, wax, honey, bee grubs and pollen - to see how much the colony had grown. Compared to control colonies not exposed to imidacloprid, the researchers found the treated colonies gained less weight, suggesting less food was coming in. The treated colonies were on average eight to 12 percent smaller than the control colonies at the end of the experiment, and also produced about 85 percent fewer queens - a finding that is key because queens produce the next generation of bees.

From the previous paragraph, which of the following changes to the bee can be inferred to have happened, and which can be inferred to NOT have happened. Make only two selections, one in each column.

A Web 2.0 symposium is looking to Silicon Valley for some tech developers to talk about the latest disruptions in our technology-based world today. There will be a morning session and an afternoon session. Each session will have 5 developers. To reflect the diverse changing world of programming, the majority of the developers in one of these sessions will be developers who are not web developers. In the other session, at least 4 of the developers will be women. Neither session should have more than two developers from the same company.
