In order to better control traffic at a certain busy intersection, a study was conducted to determine how many vehicles passed through the intersection during various times of day and what trajectories they took. For each possible trajectory (combination of direction from which a vehicle entered the intersection and direction to which it exited the Intersection), the graph shows the number of vehicles passing through the intersection during a certain hour.

Shereen cosmetics sometimes discount the price of its premium eye shadows to retailers for a promotion period when the product is advertised to consumers. Such promotions often result in a dramatic increase in amount of premium eye shadows sold by the manufacturers to retailers. Nevertheless, the manufacturers could often make more profit by not holding the promotions.
Which of the following, if true, most strongly supports the claim above about the manufacturers' profit?

Television picture quality improves as resolution increases. However, the resolution at which a given improvement in resolution becomes visible varies with the distance of the viewer from the screen. As a viewer moves closer to the screen, a given improvement in resolution eventually becomes noticeable, finally conferring its "full benefit" at a point at which moving closer would not improve the viewing experience.
On the graph, 480p, 720p, 1080p, and 1440p represent four common degrees of resolution: greater numbers indicate greater numbers of pixels on the screen and thus greater resolution. Shaded portions show the distances at which these resolutions become noticeable, while the broken lines show the maximum distances at which a viewer with normal eyesight would be expected to experience full benefit-all as a function of screen size. For each resolution and screen size shown, there is a small gap between the maximum distance for full benefit from the resolution and the minimum distance for noticeable benefit from the next higher resolution.
(Note: 3 feet is roughly 1 meter, and 1 inch is roughly 2.5 centimeters.) Assuming that the information contained in the graphic correctly applies to all viewers, select from the drop-down menus the options making the statements most accurate.

Child's World, a chain of toy stores, has relied on a "supermarket concept" of computerized inventory control and customer self-service to eliminate the category of sales clerks from its force of employees. It now plans to employ the same concept in selling children's clothes.
The plan of Child's World assumes that

Determining the authenticity of purported pre-Columbian artifacts is never easy. Carbon-14 dating of these artifacts is often impossible due to contamination by radioactive palladium (which occurs naturally in the soils of Central and South America). However, historians and anthropologists have evolved two reliable criteria, which, utilized in combination, have proven effective for dating these artifacts. First, because authentic pre-Columbian artifacts characteristically occur in a coarse, granular matrix that is shifted by major earthquakes, they often exhibit the unique scratch patterns known as girding. In addition, true pre- Columbian artifacts show a darkening in surface color that is caused by centuries of exposure to the minute amounts of magnesium in the soil of the Americas.
The criteria above would be LEAST useful in judging the authenticity of which of the following?
