Many criminologists argue that the chances that firsttime 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 firsttime offenders sentenced to community service go on to commit further crimes fully 60 percent of firsttime 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 firsttime offenders they consider likely to commit further crimes.

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

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 wellseparated asteroids impact Earth nearly simultaneously, their relatively frequent occurrence serves as evidence for the existence of a substantial population of coorbiting asteroids.
Are other rocky planets subject to impacts from coorbiting 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 coorbiting asteroids must be common among both the nearEarth and nearVenus asteroid populations.
