Twelve healthy volunteers with the Apo-A- IV-l gene and twelve healthy volunteers who instead have the Apo-AIV-2 gene each consumed a standard diet supplemented daily by a high-cholesterol food. A high level of cholesterol in the blood is associated with an increased risk of heart disease. After three weeks, the blood cholesterol levels of the subjects in the second group were unchanged, whereas the blood cholesterol levels of those with the Apo-A-IV-l gene rose 20 percent.

Which of the following conclusions is best supported by the statement above?
Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmospheric carbon causes the atmosphere to hold less heat, which causes decreased evaporation from the oceans, which causes less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax—nature will continually adjust the carbon level.
Each of the following can be inferred from the information in the passage EXCEPT:
The distance that animals travel each day and the size of the groups in which they live are highly correlated with their diets. And diet itself depends in large part on the sizes and shapes of animals’ teeth and faces.
The statements above provide the most support for which one of the following?
When a threat to life is common, as are automobile and industrial accidents, only unusual instances tend to be prominently reported by the news media. Instances of rare threats, such as product tampering, however, are seen as news by reporters and are universally reported in featured stories. People in general tend to estimate the risk of various threats by how frequently those threats come to their attention.
If the statements above are true, which one of the following is most strongly supported on the basis of them?
Sarah: "I don't understand why you recycle so much. The recycling program costs the city several million dollars a year. Trash disposal at the landfill costs half as much per household than the municipal recycling program. It just doesn't seem cost effective to have a recycling program."
Lauren: "The point of recycling isn't to save money. By recycling, we keep thousands of tons of materials out of our landfills, which mean we can use the same landfills longer. It's about conserving our resources, not about saving money on trash pickup."
Lauren's response to Sarah serves to
Shareholder: The company’s current operations are time-proven successes. The move into food services may siphon off funds needed by these other operations. Also, the food service industry is volatile, with a higher inherent risk than with, for instance, pharmaceuticals, another area into which the company has considered expanding.
