Many criminologists argue that the chances that first-time offenders will be rehabilitated can be improved by giving them sentences that promote their reintegration into society rather than by sentencing them to jail. In support of this hypothesis, it is often pointed out that whereas 10 percent of first-time offenders sentenced to community service go on to commit further crimes fully 60 percent of first-time offenders who are imprisoned do so. The hypothesis thus seems strongly confirmed. In actual fact, however, the statistics cited do little to prove it, since judges tend to impose jail sentences on those first-time offenders they consider likely to commit further crimes.

One characteristic of terrestrial cratering is the presence of doublet craters: 3 of the 28 large impact craters on Earth (greater than 20 kilometers diameter) have partner craters. For example, the Kamensk crater in Russia, 25 kilometers in diameter, is partnered by the Gusev crater, 3 kilometers wide and of identical age. Since such doublets form when two well-separated asteroids impact Earth nearly simultaneously, their relatively frequent occurrence serves as evidence for the existence of a substantial population of co-orbiting asteroids.
Are other rocky planets subject to impacts from co-orbiting asteroids? Venus is a promising planet to search for doublets because its surface is young, erosion is nearly nonexistent, and its rater population is significantly larger than Earth's, but not so large that there is a high probability of chance associations. Researchers found that the proportion of doublet craters on Venus is significantly smaller than on Earth. However, Venus` denser atmosphere may screen out the smaller member of some asteroid pairs. If Earth had a similar screening effect, only one of its three known doublets would have formed, making the proportion of doublet craters on Earth(3.6%) identical to Venus'(2.2%) within uncertainties. The researchers concluded that co-orbiting asteroids must be common among both the near-Earth and near-Venus asteroid populations.

New Zealands lesser short-tailed bat, Mystacina tuberculata, is one of only two bat species to use a true walking gait when maneuvering on the ground. It has been assumed that the specialized terrestrial habits of mystacinids evolved in New Zealand following their isolation there. Absence of native terrestrial mammalian predators in New Zealand has been hypothesized to have facilitated evolution of terrestriality. However, although it is likely that terrestrial foraging by extant Mystacina tuberculate makes it vulnerable to introduced mammalian predators, there is as yet limited available data on the actual risk of terrestriality. Indeed, Lloyd argues that although some individuals may be caught on the ground, generally they would not be easy prey: they are cryptic, fast-moving, with acute hearing and olfaction, and can quickly take flight.

The passage is primarily concerned with

Which of the following can be inferred from the passage about Mystacina tuberculate?

The manuscripts of the eight extant Latin tragedies identify the lays as the Marci Lucii Annei Senecae Tragoediae. Since nobody of that name is known. modern scholars believe the dramas to be the work of Lucius Annaeus Seneca the Younger, the well-known philosopher, orator, and politician. Clearly, the tragedies were written during Seneca's lifetime: internal references to earlier poets, most notably Ovid, indicate that the dramas cannot have been composed prior to the second decade C E, and the plays must have been written by 96 C.E., when Quintilian quotes Medea, one of the tragedies.
It is remarkable, however that Seneca himself never mentions the plays, since there are certainly passages in them that could be used to illustrate points of his philosophy. There are at least two possible explanations In the early Roman Empire, playwrights were sometimes exiled or executed for lines construed as directed against the emperor; thus, Seneca's silence may be simple prudence. But if anyone could safely attach his name to dramas surely it would be Seneca, the emperor's tutor. And although Herrmann offers Seneca's modesty as an explanation, Seneca is not averse to referring to his other writings. The evidence for equating Seneca with the author of the tragedies seems circumstantial.

The author of the passage makes which of the following claims about the eight extant Latin tragedies?

Each of the following assertions consistent with Seneca's authorship of the plays appears in the passage EXCEPT:

All the music from fourteenth-century Europe for which written scores survive is so complex and is written in such difficult notation that it could have been played only by musicians whose lives were dedicated solely to such performance. Yet fourteenth-century European accounts, which in this respect probably give accurate portrayals of their times, describe many members of the nobility who excelled not only in musical performance, but also in dancing poetry, and painting.

The statements given, if true, most strongly support which of the following?

More appropriate water pricing would promote the treatment and reuse of urban wastewater for agricultural irrigation and also encourage improvements in irrigation efficiency. Treatment and reuse is more expensive than most irrigation-related conservation and efficiency measures but often less expensive than developing new water sources. Wastewater contains nitrogen and phosphorus which can be pollutants when released to lakes and rivers but are nutrients when applied to farmland. Moreover, unlike many other water sources, treated wastewater will be both an expanding and fairly reliable supply, since urban water use will likely double by 2025. Many large cities located along coastlines currently dump their wastewater treated or untreated, into the ocean, rendering it unavailable for any other purpose and harming coastal marine life.

Which of the following does the author suggest as an incentive to the development of more efficient irrigation?
